Subject: [XML-SIG] Excel (XML): how retrieve contents of cell

1. I'm comparatively new to Python, very new to XML

I'm willing to read. What book(s)?

Please, I need advice.

"Python Programming on Win32" by Hammond and Robinson, from  
O'Reilly.  At least, if you don't need XML.  Instead, use win32com  
automation to get the data directly from Excel.  If using XML is a  
requirement, I defer to others' experience, but I think you might be  
using the wrong tool for the job.

Also, I'd suggest Fredrik Lundh's ElementTree as a much friendlier  
XML toolkit.

Hi,

URL
	http://cvs.jankratochvil.net/viewcvs/*checkout*/nethome/bin/xbelnormalize?rev=HEAD

for UNIX/Perl trivia xbelnormalize(1) to .xbel:
 * Reindent to a unified form.
 * Reencode to unified utf-8.
 * Strip any useless variable content (tested only with Galeon web browser).

to prepare the file for convenient CVS commits/updates/CVS conflicts
resolution.

It is also possible to meaningfully diff(1) the resulting files (a requirement
for CVS usage as a real versioning system).

I did not found such simple and clear to use tool for .xbel, I did not find any
tool for .xbel version management.

Another solution is to use a XML-aware diff such as xmldiff
(http://www.logilab.org/projects/xmldiff). Some version control
systems like Subversion (http://subversion.tigris.org/) can be told to
use such a diff instead of their normal diff, thus making them able to
process intelligently XML files.

Thanks for info, in some cases it may be useful. It is still would not be IMO
acceptable diffing of .xbel due the dynamic content (timestamps/folding/smth)
which is not stipped out without xbelnormalize(1). And anyway I am still
sticked with CVS as even subversion sucks...

Subject: [XML-SIG] Using XML Namespaces in XPath Expressions from Python
Message-ID: <17063.78.877780.443210@gargle.gargle.HOWL>

I'm having trouble using PyXML to evaluate XPath expressions that
include namespace references.

Here is a sample Python snipped:

    #!/usr/bin/env pystart

    import sys
    import xml.dom.minidom

    from xml.xpath.Context import Context
    from xml.xpath import Evaluate
    from xml.xpath.NamespaceNode import NamespaceNode


    if __name__ == "__main__":
      sys.stderr.write("XPathTest: 18\n")

      inputDom = xml.dom.minidom.parse(open("xpathtest-input.xml"))

      sys.stderr.write("Node: %s\n" % (inputDom.documentElement))
      outContext = Context(inputDom.documentElement)
      sys.stderr.write("NSes=%s\n" % (outContext.nss()))

      result = Evaluate("count(/dbq:Contract)",
                        contextNode=inputDom.documentElement,
                        context=outContext)
      sys.stderr.write("Eval xpath \"count(/dbq:Contract)\": %d\n" % result)

Here is what xpathtest-input.xml looks like:

    <?xml version="1.0"?>

    <dbq:Contract
        xmlns:dbq="http://dtd.itasoftware.com/Dubuque">
      <dbq:RuleContent/>
    </dbq:Contract>

Here is the output I get

[xsl] zyp| xpathtest.py                              
XPathTest: 18
Node: <DOM Element: dbq:Contract at 0x82a5a6c>

    self._prefix)
xml.xpath.RuntimeException: Undefined namespace prefix: "dbq".
exit status: 1


I can see from the output that the Context object I am passing to
Evaluate() includes the DBQ namespace. But apparently that is not
enough.

Can anyone tell me what I am doing wrong?

Where are you passing in the NS mapping here?  Did I miss a PyXML XPath
update that defaults mappings to in-scope namespaces on the node passed
in?

I think this line is your problem.  It overrides the next (probably not
sensible, which is why we reversed that priority in 4Suite ages ago).

That's the nub of my question. How do I pass namespace mappings into
Evaluate()? 

The only thing I could see to try, from looking at the documentation,
was to use the context argument. The Context object holds namespace
objects, so I thought that that might be the way to pass in my
definition. 

As you can see from the output, the Context I get from the document
node already has the "dbq" namespace defined (since it appears in the
input), before I call Evaluate(). However, it apparently gets reset
during the call to Evaluate().

OK. If I leave out that line and instead do the following:
    result = Evaluate("count(/dbq:Contract)",
                      contextNode=inputDom.documentElement)


I still get the following error:

Node: <DOM Element: dbq:Contract at 0x82ac2e4>
Traceback (most recent call last):
  File "xpathtest-1.py", line 20, in ?
    contextNode=inputDom.documentElement)

    self._prefix)
xml.xpath.RuntimeException: Undefined namespace prefix: "dbq".

Which me leaves my initial question: how do I use xml.xpath.Evaluate()
on an XPath expression that refers to namespaces?

For completeness, here is my Python:

    import sys
    import traceback
    import xml.dom.minidom

    from xml.xpath.Context import Context
    from xml.xpath import Evaluate
    from xml.xpath.NamespaceNode import NamespaceNode


    sys.stderr.write("XPathTest: 1\n")

    inputDom = xml.dom.minidom.parse(open("xpathtest-input.xml"))

    sys.stderr.write("Node: %s\n" % (inputDom.documentElement))

    result = Evaluate("count(/dbq:Contract)",
                      contextNode=inputDom.documentElement)
    sys.stderr.write("Eval xpath \"count(/dbq:Contract)\": %d\n" % result)

and here is my input:

    <?xml version="1.0"?>

    <dbq:Contract
        xmlns:dbq="http://dtd.itasoftware.com/Dubuque">
      <dbq:RuleContent/>

Use xml.dom.minidom.  Do not use xml.dom.ext.reader.*.

dom = minidom.parse("test.xml")

Yes, but you have to give it the namespace defs, as above.

That's what's confusing me.  I'm not sure why it automatically has that
namespace at any point.  Anyway, see if my suggestion helps.

I'm using SAX to load XBEL files, and I noticed that when my computer
is not connected to the Internet, the script fails with an error about
not being able to find the DTD that is referenced in the file. Is
there some way to turn off searching for the DTD?

ANN: Amara XML Toolkit 1.0b3

http://uche.ogbuji.net/tech/4Suite/amara
ftp://ftp.4suite.org/pub/Amara/

Changes in this release:

* Add xml_set_attribute method to elements, in order to allow adding
  attributes with namespaces or with illegal Python names
* Update manual source for markdown, and extensive improvements to the
  manual (with much help from Jamie Norrish)
* Add xml_doc facility for nodes [1]
* Fix support for output parameters in xml()
* Add support for rules to pushbind
* Improve XSLT support for bindery objects (see demo/bindery/xslt.py)
* Bug fixes

[1] http://lists.fourthought.com/pipermail/4suite/2005-June/013671.html

Amara XML Toolkit is a collection of Python tools for XML processing--
not just tools that happen to be written in Python, but tools built from
the ground up to use Python idioms and take advantage of the many
advantages of Python.

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 

<monty>
  <python spam="eggs">What do you mean "bleh"</python>
  <python ministry="abuse">But I was looking for argument</python>
</monty>

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 1.0b1 or more
recent.  Make sure these are installed, unpack Amara to a convenient
location and run

python setup.py install

Subject: [XML-SIG] lxml 0.7 released!
Message-ID: <42B05FF3.4000701@infrae.com>

Hey everybody,

I've just released lxml 0.7. lxml is a Pythonic wrapper for libxml2 and 
libxslt. It aims at ease of use of the API for Python programmers and 
exposing the many libxml2 features. lxml implements the Python 
ElementTree API on top of libxml2. It extends this with support for 
XPath, XSLT, Relax NG, XML schema and more.

lxml 0.7 is a release with quite a few new features and bug fixes, 
including XPath expression parameters, XInclude  support, XMLSchema 
validation support, more namespace prefix support, better encoding 
support, and more.

More information plus download can be found here:

Regards,

Martijn

Subject: [XML-SIG] XBEL and hyperlink tagging
Message-ID: <200506171758.j5HHwmYG006534@ms-smtp-03-eri0.ohiordc.rr.com>

I'd like to get in touch with anyone from the XBEL group who has an interest
in hyperlink tagging. I am chronically frustrated with managing my bookmarks
and have tried hundreds, I'm sure, of solutions. Recently I tried
del.icio.us and subsequently started reading a lot of blog banter about
hyperlink tagging. After years of wishing for the right solution, I've
decided to see if I can actually contribute something to a solution.
 
I believe xml-based tags are the answer to managing link collections, and
XBEL is a fine format, so I'm wondering if it can be expanded to accommodate
a standard hyperlink tag. I'm including both a graphical and outline version
of a brainstorm document I started last night. It's very rough and just the
beginning of an idea. 
 
My goal is an open-source, standard hyperlink tag solution that is highly
accessible to software developers, amateur coders and web site owners whose
primary expertise is not programming. If no one in your group has any
interest in this, I would greatly appreciate any input or advice anyone
would share. I have no idea how things like standard tag formats are born. 
 
Thanks.

Why are you using such an old version of PyXML? 0.8.2 dates back to January 2003.

This was fixed in PyXML 0.8.3, released July 2003.
Please use the current version of PyXML, 0.8.4, released in November 2004.

Hi, Danielle!

It's nice to see, that there are some people out there who still want to work 
on a standardised way to store and share hyperlinks. 

But the XBEL format isn't ready to the job! Months ago I proposed to resume 
the work on XBEL and perhaps make it a independent project. But at that time 
there wasn't enough interest.

We should dare!

Regards,
Christian

P.S.: Perhaps you like to take a look at the xml-sig archive to find the old 
discussion (dec 04 and jan 05) ...

doc = xml.dom.minidom.parseString(data)
root = doc.documentElement
...add and modify some nodes...
sys.stdout.write(root.toxml('utf-8'))

A typical input looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE lec SYSTEM "swc.dtd">
<lec title="Introduction">
   <topic title="Motivation" summary="motivation for course">
     <slide>
       <b1>blah
         <b2>blah &amp; blah</b2>
         <b2>blah&emdash;blah</b2>
       </b1>
     </slide>
   </topic>
</lec>

and my DTD, in its entirety, is:

<!ENTITY emdash "&#x8212;">	<!-- em dash -->
<!ENTITY lceil  "&#x2308;">	<!-- left ceiling -->
<!ENTITY ldots  "&#x2026;">	<!-- horizontal ellipsis -->
<!ENTITY lfloor "&#x230A;">	<!-- left floor -->
<!ENTITY lquot  "&#x201C;">	<!-- left double quotes -->
<!ENTITY plusmn "&#x0177;">	<!-- plus or minus -->
<!ENTITY nbsp   "&#x00A0;">	<!-- non-breaking space -->
<!ENTITY rceil  "&#x2309;">	<!-- right ceiling -->
<!ENTITY rfloor "&#x230B;">	<!-- right floor -->
<!ENTITY rquot  "&#x201D;">	<!-- right double quotes -->
<!ENTITY space  "&#x0020;">	<!-- normal space -->
<!ENTITY squot  "&#x0022;">	<!-- straight double quotes -->
<!ENTITY times  "&#x00D7;">	<!-- multiplication sign -->
<!ENTITY vdots  "&#x22EE;">	<!-- vertical ellipsis -->

Problem is, all of the character entities are missing from my output: 
&amp; and &emdash; disappear.  Hunting around the web, it appears that 
I'm supposed to mess with ExternalEntityRefHandler, but I can't find any 
examples of how the pieces fit together.  If anyone has one, I'd be 
grateful for a pointer...

Thanks,
