Bult-in XSLT processor

Bult-in XSLT processor

[Etienne Prud’homme]

While trying to discover XSLT, I saw that Emacs doesn’t seem to have an
XSLT processor built-in.  That surprised me given it can be used in a
variety of contexts (I’m still discovering that though).

I’m not talking about XSLT editing functionality.  nXMl-mode seems to do
a pretty good job on XML documents (XSLT is XML based).  I’m talking
about a library that can transform XML file according to an XSLT
stylesheet.

The only support I’ve seen so far is by using the very old
`xslt-process' package and it’s using Java libraries.

Would it be worth the effort to make an XSLT processor in Emacs Lisp?

Have you tried libxslt and its xsltproc tool?

We would have to include yet another library to support.  Since we had a
built-in XML processor, I thought including an XSLT processor would be
beneficial (while not excluding supporting libxslt).

To respond to the question, yes I have tried it ;-)

What do you mean by "built-in XML processor"?

And we do use libxml2 for supporting various features.

I meant the _xml.el_ library.  I didn’t take a look at the current use
of libxml2, but I assumed that _xml.el_ was mostly the parser used.

Ah, okay.  But isn't the implementation ion xml.c based on libxml2
faster?
