There are a couple. We plan to integrate FourThought's 4XSL with Zope.

Thanks for the pointer. Unfortunately it only works on Unix, though.

I expect this will look like "XSL methods".

Well, how would you invoke them? It would be appropriate, say, to have a single folder's XML documents all point to one XSL style sheet. In fact, since the XSL style sheet of a document can be defined in the XML itself -- the syntax escapes me, but I believe it was an XML SI -- this information could be used for overriding the "default" XSL style sheet.

Also node that *all* Zope objects support DOM at some level as of Zope 2.0 beta 1.

Any examples of this?

Guessing wildly, but I believe that you are thinking of XSL as meaning the "Document Type Definition" (DTD) for a given class of XML documents: the DTD defines the allowable elements/attributes for its class, and is normally referenced at the head of the document; it can be defined or overridden within the document itself. XSL is a slice-and-dice query/transformation language, based on the DSSSL beloved of SGML geeks (itself based on Scheme, I think). An XSL style-sheel _renders_ an XML document, just as DTML renders Zope objects. Frankly, the most exciting news about the XMLDocument is that I can put off learning XSL, and just use DTML and Python instead. -- ========================================================= Tres Seaver tseaver@palladion.com 713-523-6582 Palladion Software http://www.palladion.com
