I will contact Martin Karlsch as soon as I have ordered the mess in my mind. ;) I found his master thesis and (with some surprise) have seen your name along with Markus Hillebrand's. Last week he mentioned such project (I'm sure now that he referred to frodo). However, I had the feeling that probably it is too challenging for my skill level, but I will try to understand the basic principles, at least. BTW, I have replaced PyXML Sax2 reader with xml.dom.minidom from Python standard library, as you suggested on 2007-02-07 in this list. Hasn't been much work to change and the new version (0.7.1) runs fine. I also noticed that with minidom's parse() the generator is ~ 5 times faster than before, where all time-saving seems to be originated from the XML parsing. Many thanks for your advice.

I found that the existing xml.dom module had some serious bugs, has not been touched since 2004, and had no easy way of creating and inserting subtrees in the DOM, or working with subsets of the DOM. This looks like it was written, then abandoned for some reason. Not sure why. I tried to use the elementree from effbot, but also with no success. It is not DOM compliant, and it's nesting is odd. For example, text appearing after a

... node. I found it very odd, and not useful for DOM manipulation at all. I wrote to Mr. Lundh, and got an indifferent response. I ended up writing my own DOM tree manager, which is DOM 2 compliant for the most part. A range() interface still needs to be fully written, which will allow it to reference anywhere in the tag structure arbitrarily. Right now I limit my DOM referencing to well-defined components of the tags and elements. I have not yet written the code to allow for a completely unlimited referencing of content in any node, and across any range. Once that is added to my module, it will be complete and even more DOM2 compliant. But that functionality is not required for my app, so I may not get the chance to write it. It has the ability to work with any subtree and insert it using array syntax. The nesting is exactly what you'd expect in a DOM structure. If you want this module, and you reach the point where you can help me debug and improve it, then contact me and we shall talk about the details. based on this e-mail, it sounds like you're not yet there. For serving RESTful front end app, I highly recommend CherryPy.

I'm trying to run InkScape in Mac Os X (a vector graphics application). The prepackaged application runs fine, in general. However, many of its modules use a python script named inkex.py, which fails with the message that it requires PyXML. I tried searching for the solution, but it seems to me the XML support in Python has changed a bit and perhaps you can help me understand what the current best solution is. It seems PyXML is deprecated or no longer maintained according to its SourceForge page. I believe Python 2.5 (which is what I'm running on the Mac) has some of the XML support already built in. The inkex.py script tries to import the following: try: import xml.dom.ext import xml.dom.minidom import xml.dom.ext.reader.Sax2 import xml.xpath except: sys.exit('The inkex.py module requires PyXML. Please download the latest version from .') Of these, minidom seems to be present, but the others aren't: Python 2.5 (r25:51918, Sep 19 2006, 08:49:13) [GCC 4.0.1 (Apple Computer, Inc. build 5341)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import xml.dom.ext Traceback (most recent call last): File "", line 1, in ImportError: No module named ext >>> import xml.dom.minidom >>> import xml.dom.ext.reader.Sax2 Traceback (most recent call last): File "", line 1, in ImportError: No module named ext.reader.Sax2 >>> import xml.xpath Traceback (most recent call last): File "", line 1, in ImportError: No module named xpath >>> Any ideas or pointers will be very much appreciated Juan C.

The user provides definitions (source) for the methods to be added and (for each method) a regular expression to identify the names of classes to which the method should be added. Then, the --user-methods command line flag is used to instruct generateDS.py to add the specified methods to the classes generated in the superclass file. A class variable (_member_data_items) providing information about the member data items of each generated class has also been added. There is a sample file (gends_user_methods.py in the distribution) that provides examples of: - walking the document object tree, - accessing member data items using the _member_data_items class variable, - getting and setting the values of member data items, and - determining the type of member data items. You can read more about this capability in the "User Methods" section of the documentation: http://www.rexx.com/~dkuhlman/generateDS.html#user-methods You can find the latest version here: http://www.rexx.com/~dkuhlman/generateDS-1.10a.tar.gz and at Source Forge: http://sourceforge.net/projects/generateds/ If you consider using this new user methods capability, also think about the ability to generate subclasses of generated classes using the -s command line flag and then manually adding methods to those generated subclasses. In some situation, this might be a better solution.

That should work fine for most aspects. The only problematic issue is xpath: Python currently does not include an xpath implementation. Depending on what xpath expressions are used, you may be able to reformulate the queries directly in DOM.

Here are some of highlights: * Query Plan: A new query plan utility in the XQuery Editor lets you visualize query execution plans and gain insight into how DataDirect XQuery will execute your XQuery application, including seeing the type of SQL statements that are used to access relational data, when XML streaming is being used, which temporary tables are being created, when variables are being called, etc. Query plan support is available for any XQuery that uses the DataDirect XQuery processor. * Support for Grouping Data Sources in XML Publisher: In Stylus Studio 2007 XML Enterprise Suite, Release 2, XML Publisher lets you create more advanced reports through support for grouping data from nodes in one or more data sources. Using the new Create Relationship Dialog Box, you visually define relationships between different data sources, or between different data islands within the same source and then add those relationships to your XML reports using simple drag-and-drop functionality. For more information, visit: http://www.stylusstudio.com/videos/report-generation/xmlpublisher-070504.html * Support for Gigabyte Size XML Files: Stylus Studio 2007 XML Enterprise Suite, Release 2 implements new optimizations that permit the editing of gigabyte-size XML documents. * Bundled DataDirect XML Converters 3.0: DataDirect XML Converters are high-performance Java and .NET components that provide bi-directional, programmatic access to virtually any non-XML file including EDIFACT, X12, IATA, EANCOM and flat files. For more information, visit: http://www.xmlconverters.com * Bundled DataDirect XQuery 3.0: DataDirect XQuery is an implementation of XQuery that can query XML, relational data, SOAP messages, EDI, or a combination of data sources.
