MS XML parser only works with IE...

The MSXML dependencies on Windows are apparently trivial and fixable.
Equally important, the MSXML EULA grants the right to redistribute such
modified code. See the three letters (from the xml-dev mailing list)
that I include at the end of this letter for more information. What I'd
like to see is someone post these fixes so that each person wanting
the portable version doesn't have to make the changes by hand. If
does this (clovett, you listening? :) and lets me know, I'll write it up
in the news.
Regarding MSXML's break with the XML spec, I was unaware of the </> and
notation -- it was discussed in the xml-dev mailing list right before
I joined. It looks like Microsoft is, for once, interested in hearing
constructive feedback. In particular Chris Lovett
(clovett at microsoft.com)
has encouraged such feedback. Anyone interested in this topic should
send him polite mail requesting that MS stick to the spec.
I can understand why you would be upset about this. The splintering
by Microsoft of a great new technology is something that we Java
programmers seem mysteriously sensitive to. ;) Nevertheless, I'll stand
by my statement that MSXML is arguably the best XML parser for Java
There are other choices, such as Lark (http://www.textuality.com/Lark/)
and NXP (http://www.edu.uni-klu.ac.at/~nmikula/NXP/preview/).
I'm cc'ing this to the xml-dev mailing lists in the hopes that it
will rekindle the discussion on the importance of sticking to the

Exerpts from three letters on the xml-dev mailing list
regarding XML's ties to Windows
> Windows dependency of MSXML is minimal. All you have to do is following:
> 1. remove com.ms.xml.dso package.
> Delete the class files from the jar and/or comment it out of the makefile.
> DSO is accessed by some of the samples but none of the other MSXML packages.
> 2. remove dependency on com.ms.xml.xmlstream package.
> Latest version of MSXML includes an alternate XMLInputStream class located
> inside the 'make' directory. Replace com.ms.xml.util.XMLInputStream with
> the alternate version to remove dependency on com.ms.xml.xmlstream package.
> WIth above two changes, you will end up with a pure-Java version of MSXML.
> MSXML is the most complete XML parser available right now and you get the
> source code on top of it. I would be smiling by now if I were you :-)
