Thanks in advance From mertz at gnosis.cx Thu Apr 7 06:36:07 2005 From: mertz at gnosis.cx (David Mertz, Ph.D.) Date: Thu Apr 7 06:38:45 2005 Subject: [XML-SIG] [Announce] Gnosis Utils 1.2.0 Message-ID: <3iLVClKkXIiW092yn@gnosis.cx> David Mertz (mertz@gnosis.cx) Frank McIngvale (frankm@hiwaay.net) This release of the Gnosis Utilities contains several new modules, as well as fixes, enhancements, and speedups in existing subpackages. Try it out, have fun, send feedback! NEW SUBPACKAGES ------------------------------------------------------------------------ ADDED gnosis.utils.hashcash (also runs standalone). Python implementation of Hashcash v.1 (backward compatible with hashcash v.0). ADDED disthelper. A collection of scripts and modules that are generally useful for building/maintaining a Python source distribution. - To use disthelper in your own distribution, copy the entire disthelper/ tree into the toplevel of your tree, as has been done in Gnosis_Utils. - See disthelper/README for details. ADDED gnosis.pyconfig. Detect actual capabilities available in a Python interpreter. gnosis.pyconfig lets you write much more robust/readable code than simply relying on sys.version_info. ADDED gnosis.xml.xmlmap. Unicode->XML legality testing & Unicode helper functions. - For detailed background information on the motivation for this module, see "All About Python and Unicode" at: http://boodebr.org/python/pyunicode/index.html ENHANCEMENTS ------------------------------------------------------------------------ There is one critical change in gnosis.xml.pickle; all xml.pickle users are encouraged to upgrade. Catch unpickleable data in gnosis.xml.pickle and abort, instead of creating pickles that can't be reloaded. - Recommend all xml.pickle users upgrade to 1.2.0. - Issues: not all valid Unicode strings are valid XML CDATA or attribute values. - There have not been any reports of data loss due to this, but it is a possibility with 1.1.1. - A future Gnosis release will fix this so that the 'bad' data can be pickled, instead of just bailing out. Numerous new convenience functions for gnosis.xml.objectify. See gnosis/docs/xml_matters_39.txt for more discussion. - addChild() # moved to utils subpackage - walk_xo() # Recursively traverse the nodes - write_xml() # Serialize an _XO_ object back into XML - XPath() # Find node(s) within an _XO_ object - pyobj_printer() # moved to utils subpackage Some of older conveniences have been tweaked and/or were not announced previously: - content() # The (mixed) content of o as a list - children() # The child nodes (not PCDATA) of o - text() # List of textual children - dumps(): # The PCDATA in o (preserves whitespace) - normalize() # Whitespace normalize string, # e.g. o.PCDATA==normalize(dumps(o)) - tagname() # The element tag o was generated from - attributes()# List of (XML) attributes of o Fixed two bugs causing leaks in long running gnosis.xml.objectify processes (file close and expat base class). Significant speedups by miscellaneous refactoring/cleanup in gnosis.xml.objectify. Fixes to gnosis.xml.indexer suggested by Uche Ogbuji. Security fixes to gnosis.utils.convert.dmText2Html. DOWNLOADING: ------------------------------------------------------------------------ Browse the latest development snapshot or download it using 'wget -r' or similar tools: http://gnosis.cx/download/gnosis/ It may be obtained at: http://gnosis.cx/download/Gnosis_Utils-1.2.0.tar.gz The current release is always available as: http://gnosis.cx/download/Gnosis_Utils-current.tar.gz Other distribution formats and older versions can be found at: http://gnosis.cx/download/Gnosis_Utils.More/ BACKGROUND: ------------------------------------------------------------------------ Gnosis Utilities contains a number of Python libraries, most (but not all) related to working with XML. These include: disthelper (Create more flexible distutils archives) gnosis.indexer (Full-text indexing/searching) gnosis.xml.pickle (XML pickling of Python objects) gnosis.xml.objectify (Any XML to "native" Python objects) gnosis.xml.validity (Enforce validity constraints) gnosis.xml.relax (Tools for working with RelaxNG) gnosis.xml.indexer (XPATH indexing of XML documents) [...].convert.txt2html (Convert ASCII source files to HTML) gnosis.util.dtd2sql (DTD -> SQL 'CREATE TABLE' statements) gnosis.util.sql2dtd (SQL query -> DTD for query results) gnosis.util.xml2sql (XML -> SQL 'INSERT INTO' statements) gnosis.util.combinators (Combinatorial higher-order functions) gnosis.util.introspect (Introspect Python objects) gnosis.utils.hashcash (Hashcash proof-of-work protocol) gnosis.magic (Multimethods, metaclasses, etc) gnosis.trigramlib (Work w/ trigrams, e.g. spam filtering) gnosis.pyconfig (Capability-based version adaptation) ...and so much more! :-) From and-xml at doxdesk.com Thu Apr 7 19:56:16 2005 From: and-xml at doxdesk.com (Andrew Clover) Date: Thu Apr 7 19:55:36 2005 Subject: [XML-SIG] validate dom tree object In-Reply-To: References: Message-ID: <42557440.5020308@doxdesk.com> Leticia Larrosa wrote: > i found that the function "create_input_source" in the following code > that are placed in the module "xml.parsers.xmlproc.xmlapp": > "A class that creates file-like objects from system identifiers." > don't accept a instance of a xml dom tree. That's correct. A DOM tree is not a system identifier (effectively, a URI). > My question is if exist a way of validate a xml dom tree object, not a xml > file. Not currently as far as I know. For reasons of tradition, validation is typically done at parse-time. There is no standard way in the W3C DOM interface to retain the information from and declarations in the DTD, so most Python implementations do not keep this information, which is needed to do validation. (My own imp pxdom does keep the information, in a non-standard extended interface. So it would be possible to create a DOM-based validator based on this... it's something I'm considering doing myself, but not a priority at the moment.) -- Andrew Clover mailto:and@doxdesk.com http://www.doxdesk.com/ -- Andrew Clover mailto:and@doxdesk.com http://www.doxdesk.com/ From Sylvain.Thenault at logilab.fr Wed Apr 6 12:15:49 2005 From: Sylvain.Thenault at logilab.fr (Sylvain =?iso-8859-1?Q?Th=E9nault?=) Date: Fri Apr 8 08:35:48 2005 Subject: [XML-SIG] prepare_input_source and relative path In-Reply-To: <20050211084631.GA3844@logilab.fr> References: <20050210100217.GE3811@logilab.fr> <200502102015.j1AKFPsR009831@chilled.skew.org> <20050211084631.GA3844@logilab.fr> Message-ID: <20050406101549.GA4276@logilab.fr> Hi ! after some times working on other stuff, I've remembered that I had still the prepare_input_source patch pending.

I still have not had time to review and test your changes, and don't anticipate being able to do it anytime soon. :/ I would just be happy to know that in PyXML, (1) OS-specific file system paths or relative URI references are never used as base URIs; only absolute URIs are (and they can be derived from what is given, in some cases) and (2) resolution of a relative URI reference to absolute form is carried out in accordance with RFC 3986 -- e.g., via Absolutize() in Uri.py. Anything else, like the details of OS path <-> URI conversion, improvements to percent-encoding/decoding, better str vs unicode handling, IDN support, etc. is lower priority. One thing you should do is compare your Uri.py against the current one. We've made a number of changes since February, and some of them are important: http://cvs.4suite.org/viewcvs/4Suite/Ft/Lib/Uri.py?r1=1.98&r2=1.89 > PS: i'm not sure I should checkin the test_Uri.py file since it depends > on Ft test tools, and I've no time to backport it to use unittest only.

So be happy :) I've modified (actually simplified) the patch so that a ValueError is raised if a non empty but non absolute path is given to the absolute_system_id function, and actual absolutization is done with the Absolutize function. > Anything else, like the details of OS path <-> URI conversion, improvements to > percent-encoding/decoding, better str vs unicode handling, IDN support, etc. > is lower priority. +1 > One thing you should do is compare your Uri.py against the current one.

However, ElementTree doesn't support validation against external DTDs, or RelaxNG schemas. So, what would you suggest? Ease of use is more important than an all-encompassing feature set (since this is for teaching purposes); it has to be available on all major platforms (Windows, Mac, Linux, Solaris), trivial to install, and have at least some documentation.

If you wanted to reach a human being, you used the correct procedure and you can ignore the remainder of this message. If you were trying to send a command for the computer to execute, please read on. The JMCINFO list is managed by a LISTSERV server. LISTSERV commands should always be sent to the "LISTSERV" address, ie LISTSERV@LIST.MSU.EDU. LISTSERV never tries to process messages sent to the JMCINFO-request address; it simply forwards them to a human being, and acknowledges receipt with the present message. The "listname-request" convention originated on the Internet a long time ago. At the time, lists were always managed manually, and this address was defined as an alias for the person(s) in charge of the mailing list. You would write to the "listname-request" address to ask for information about the list, ask to be added to the list, make suggestions about the contents and policy, etc. Because this address was always a human being, people knew and expected to be talking to a human being, not to a computer. Unfortunately, some recent list management packages screen incoming messages to the "listname-request" address and attempt to determine whether they are requests to join or leave the list. They look for words such as "subscribe," "add," "leave," "off," and so on. If they decide your message is a request to join or leave the list, they update the list automatically; otherwise, they forward the message to the list owners. Naturally, this means that if you write to the list owners about someone else's unsuccessful attempts to leave the list, you stand good chances of being automatically removed from the list, whereas the list owners will never receive your message. No one really benefits from this. There is no reliable mechanism to contact a human being for assistance, and you can never be sure whether your request will be interpreted as a command or as a message to the list owners. This is why LISTSERV uses two separate addresses, one for the people in charge of the list and one for the computer that runs it. This way you always know what will happen, especially if you are writing in a language other than English. In any case, if your message was a LISTSERV command, you should now resend it to LISTSERV@LIST.MSU.EDU. The list owners know that you have received this message and may assume that you will resend the command on your own. You will find instructions for the most common administrative requests below. ********************* * TO LEAVE THE LIST * ********************* Write to LISTSERV@LIST.MSU.EDU and, in the text of your message (not the subject line), write: SIGNOFF JMCINFO ******************** * TO JOIN THE LIST * ******************** Write to LISTSERV@LIST.MSU.EDU and, in the text of your message (not the subject line), write: SUBSCRIBE JMCINFO ************************ * FOR MORE INFORMATION * ************************ Write to LISTSERV@LIST.MSU.EDU and, in the text of your message (not the subject line), write: "HELP" or "INFO" (without the quotes). HELP will give you a short help message and INFO a list of the documents you can order.

Message-ID: <425C93F0.5050509@dreamcatalyst.com> OK I am relatively new to python and I know this is kind of a general python question but I haven't found an answer any where else. I know you can chain filters by calling nextfilter.startElement(..) and so on. But what if you want sequential filters to modify information that might have been added to the document by a previous filter? I assume you need to parse for each filter but it doesn't matter. What I cannot figure out is how to get the results of the parse into a string that I can pass on to a second parse with a different filter. I hope I am being clear enough here. I want to parse a file and have the result put into a string that I can parse a second time using a different filter. Any suggestions? Thank You, J.

Always happy to help, and it's fun to use the time machine :-) . For completeness, I'll mention what you might have already discovered. The first optional parameter to XMLGenerator is an output buffer, and it can be a string buffer. So if instead of, as in listing 1 of the article: logger = XMLGenerator(output, encoding) You do import cStringIO #Probably want to import this at the top buffer = cStringIO.StringIO() logger = XMLGenerator(buffer, encoding) Then all the output from the generator would be accumulated in buffer, and you could get it using buffer.getvalue().

Message-ID: I'm trying to write an example of how to move elements around in a document using ElementTree. The objective is to take things like this:

Heading

 and turn them into:

Heading

i.e., put the emphasis inside the h1-h4 elements, instead of the other way around. It's almost working, but I'm still having trouble handling nodes whose children are interspersed text and elements. The script below shows the problem. Run it from the command line with no argument, and it'll break on the 'Single Inversion' text. Run it again with 'movetext' as its only argument, and it'll break on the last test (in which the body element has strings, em+heading, and other elements as children). I think the root of my problem is that I don't understand how ElementTree stores text --- if you have:

a c d f

then what are p's children? What is p.text? What happens if you assign a new value to p.text?

Highlights of changes -- * Minor to huge performance increases throughout the core libraries: * Ft.Lib.Set implemented in C, resulting in faster evaluation of XPath expressions using '/', '//', and '|') * 40x speedup in startup time for Domlette parsing * Additional optimization of XPath expressions involving '/', '//', 'child::' and others * .docindex removed from Domlette nodes; they now compare to each other in document order (e.g., when in a list, .sort() can be called for document order). Resulting XPath/XSLT speedup * XSLT whitespace stripping optimized; xml:space handling fixed * XML string utilities now in module Ft.Xml.Lib.XmlString, implemented in C, as part of Domlette optimizations * Mini-SAX interface added to the Domlette Expat library, via Ft.Xml.Sax. The "mini" is due to the fact that only the interfaces required for parsing XSLT stylesheets are exposed. * XML catalogs and XSLT stylesheets now read via the fast mini-SAX API * Many more Domlette speed and memory optimizations * RDF core: various optimizations result in speedup of RDF completes and faster database access * RDF core: better Unicode handling; improvements to the way statements are printed, compared, iterated over, reified, serialized/deserialized * RDF core: optimized RDFS validation (90% speedup plus other optimizations) plus updated to current standard * XML core: Ft.Xml.MarkupWriter introduced--very friendly interface for generating XML content based on the XSLT writers, but adding convenience methods for common element creation patterns, and for inserting chunks of "literal" markup * XML core: FtMiniDom removed * XML core: All dependencies on PyExpat removed * XML core: Domlette nodes have new attributes: * xpathNamespaces, a dict of in-scope namespaces * xpathAttributes, the node's attributes, not counting those for namespace bindings * Environment variable XML_CATALOG_FILES now supported * XPath: extension functions that access the underlying OS are now disabled by default (e.g., f:spawnv(), f:system(), f:env-var()) * In Ft.Lib.Uri.OsPathToUri and UriToOsPath, attemptAbsolute now defaults to True * XLink: xlink:show='replace' behaves more usefully & sensibly * BerkeleyDB (bsddb) RDF and repository drivers added (Py 2.3+ only) * MySQL RDF and repository drivers optimized * Repository: XSLT DocDefs repository can now use extension functions/elements * Repository: better handling of external entity resolution * Doc generation issues resolved. API docs can now be generated for every module in 4Suite (various * XHTML 1.0 Transitional DTD added to default catalog * Many more bug fixes and enhancements.

If you used 0.12.0a3, or a more recent version, then you will have to follow the migration instructions detailed in the following message: http://lists.fourthought.com/pipermail/4suite/2004-October/012933.html In general, it's worth being familiar with the following document: http://uche.ogbuji.net/tech/akara/nodes/2003-01-01/backup There have been on and off problems for Mac OS X users. We think these are now resolved. Please see the following page for current status, notes and recommendations: http://uche.ogbuji.net/tech/akara/nodes/2003-01-01/osx Installation locations have changed since 0.12.0a3 on both Windows and Unix. See the current installation directory layout document at: http://4suite.org/docs/installation-locations.xhtml If there is a server config files at the default location for the build and platform (e.g. /usr/local/lib/4Suite/4ss.conf by default on UNIX), it will be renamed to 4ss.conf.old and then overwritten.

Amara builds on 4Suite [http://4Suite.org], but whereas 4Suite focuses more on literal implementation of XML standards in Python, Amara focuses on Pythonic idiom. It provides tools you can trust to conform with XML standards without losing the familiar Python feel. The components of Amara are: * Bindery: data binding tool (a very Pythonic XML API) * Scimitar: implementation of the ISO Schematron schema language for XML; converts Schematron files to Python scripts * domtools: set of tools to augment Python DOMs * saxtools: set of tools to make SAX easier to use in Python * Flextyper: user-defined datatypes in Python for XML processing There's a lot in Amara, but here are highlights: Amara Bindery: XML as easy as py -------------------------------- Bindery turns an XML document into a tree of Python objects corresponding to the vocabulary used in the XML document, for maximum clarity. For example, the document What do you mean "bleh" But I was looking for argument Becomes a data structure such that you can write binding.monty.python.spam In order to get the value "eggs" or binding.monty.python[1] In order to get the value "But I was looking for argument". There are other such tools for Python, and what makes Anobind unique is that it's driven by a very declarative rules-based system for binding XML to the Python data. You can register rules that are triggered by XPattern expressions specialized binding behavior. It includes XPath support and supports mutation. Bindery is very efficient, using SAX to generate bindings. Scimitar: Schematron for Pytthon -------------------------------- Merged in from a separate project, Scimitar is an implementation of ISO Schematron that compiles a Schematron schema into a Python validator script. You typically use scimitar in two phases. Say you have a schematron schema schema1.stron and you want to validate multiple XML files against it, instance1.xml, instance2.xml, instance3.xml. First you run schema1.stron through the scimitar compiler script, scimitar.py: scimitar.py schema1.stron The generated file, schema1.py, can be used to validate XML instances: python schema1.py instance1.xml Which emits a validation report. Amara DOM Tools: giving DOM a more Pythonic face ------------------------------------------------ DOM came from the Java world, hardly the most Pythonic API possible. Some DOM-like implementations such as 4Suite's Domlettes mix in some Pythonic idiom. Amara DOM Tools goes even further. Amara DOM Tools feature pushdom, similar to xml.dom.pulldom, but easier to use. It also includes Python generator-based tools for DOM processing, and a function to return an XPath location for any DOM node. Amara SAX Tools: SAX without the brain explosion ------------------------------------------------ Tenorsax (amara.saxtools.tenorsax) is a framework for "linerarizing" SAX logic so that it flows more naturally, and needs a lot less state machine wizardry. License ------- Amara is open source, provided under the 4Suite variant of the Apache license. See the file COPYING for details. Installation ------------ Amara requires Python 2.3 or more recent and 4Suite 1.0a4 or more recent. Make sure these are installed, unpack Amara to a convenient location and run python setup.py install -- Uche Ogbuji Fourthought, Inc. http://uche.ogbuji.net http://fourthought.com http://copia.ogbuji.net http://4Suite.org Use CSS to display XML, part 2 - http://www-128.ibm.com/developerworks/edu/x-dw-x-xmlcss2-i.html Writing and Reading XML with XIST - http://www.xml.com/pub/a/2005/03/16/py-xml.html Use XSLT to prepare XML for import into OpenOffice Calc - http://www.ibm.com/developerworks/xml/library/x-oocalc/ Schema standardization for top-down semantic transparency - http://www-128.ibm.com/developerworks/xml/library/x-think31.html From walter at livinglogic.de Thu Apr 21 19:39:31 2005 From: walter at livinglogic.de (=?ISO-8859-1?Q?Walter_D=F6rwald?=) Date: Thu Apr 21 19:39:34 2005 Subject: [XML-SIG] XIST 2.9 has been released Message-ID: <4267E553.4030403@livinglogic.de> XIST 2.9 has been released! What is it? =========== XIST is an extensible HTML/XML generator written in Python. XIST is also a DOM parser (built on top of SAX2) with a very simple and Pythonesque tree API. Every XML element type corresponds to a Python class, and these Python classes provide a conversion method to transform the XML tree (e.g. into HTML). XIST can be considered "object oriented XSL". What's new in version 2.9? ========================== * XIST trees can now be pickled. The only restriction is that global attributes must come from a namespace that has been turned into a module via makemod, so that this module can be imported on unpickling. * Two arguments of the walk method have been renamed: filtermode has been renamed to inmode and walkmode has been renamed to outmode. For these modes two new values are supported: ll.xist.xsc.walkindex The value passed to the filter function or yielded from the iterator is a list containing child indizes and attribute names that specify the path to the node in question. ll.xist.xsc.walkrootindex The filter function will be called with two arguments: The first is the root node of the tree (i.e. the node for which walk has been called), the second one is an index path (just like for ll.xist.xsc.walkindex). If used as an outmode a tuple with these two values will be yielded. * Attribute mappings now support __getitem__, __setitem__ and __delitem__ with list arguments, i.e. you can do: >>> from ll.xist.ns import html >>> e = html.a("gurk", href=("hinz", "kunz")) >>> print e.attrs[["href", 0]] hinz >>> e.attrs[["href", 0]] = "hurz" >>> print e["href"] hurzkunz >>> del e.attrs[["href", 0]] >>> print e["href"] kunz * XML attributes can now be accessed as Python attributes, i.e. >>> from ll.xist.ns import html >>> e = html.a("spam", href="eggs") >>> print e.attrs.href eggs (Don't confuse this with e.Attrs.href which is the attribute class.) * Frag and Element now support Node subclasses in their __getitem__ method: An iterator for all children of the specified type will be returned. * The encoding used for parsing now defaults to None. When reading from an URL and no default encoding has been specified the one from the Content-Type header will be used. If this still doesn't result in a usable encoding, "utf-8" will be used when parsing XML and "iso-8859-1" will be used when parsing broken HTML. * All error and warning classes from ll.xist.errors have been merged into ll.xist.xsc. This avoids import problems with circular imports. * The attributes showLocation and showPath of ll.xist.presenters.TreePresenter have been lowercased and presenters are properly reset after they've done their job. * The class attribute xmlname will no longer be turned into a list containing the Python and the XML name, but will be the XML name only. You can get the Python name from foo.__class__.__name__. * DeprecationWarnings for name and attrHandlers have finally been removed. * Instances of ll.xist.xsc.Entity subclasses can now be compared. __eq__ simply checks if the objects are instances of the same class. For changes in older versions see: http://www.livinglogic.de/Python/xist/History.html Where can I get it? =================== XIST can be downloaded from http://ftp.livinglogic.de/xist/ or ftp://ftp.livinglogic.de/pub/livinglogic/xist/ Web pages are at http://www.livinglogic.de/Python/xist/ ViewCVS access is available at http://www.livinglogic.de/viewcvs/ For information about the mailing lists go to http://www.livinglogic.de/Python/xist/Mailinglists.html Bye, Walter D?rwald From service at mozilla.org Sun Apr 24 02:25:39 2005 From: service at mozilla.org (service@mozilla.org) Date: Sun Apr 24 02:25:37 2005 Subject: [XML-SIG] Xml-sig@python.org Message-ID: <20050424002535.F32D11E4002@bag.python.org> Your message was not delivered due to the following reason: Your message was not delivered because the destination server was not reachable within the allowed queue period.
