Hi David, Michael > From: David Tolpin [mailto:dvd@xxxxxxxxxxxxxx] > ... > Michael, > ... Yet it turns out that > XSLT 2.0 is not upto the task of converting from XSLT 1.0 to XSLT 2.0. The problem is that XSLT is not a true XML language: the XPath literals are not broken up into a tree structure. So in order to transform XSLT 1.0 it will be almost essential to delegate the XPath parse to some Java code. If there was a standard XML tree representation of an XPath, which could come in useful for all sorts of other purposes, the fn:xpath-to-tree() function would return it enabling proper XSLT analyses. The reverse fn:tree-to-xpath() is just a pretty printer. Given fn:xpath-to-tree(), it would be possible to convert XSLT 1.0 to 2.0, and perhaps this conversion should accompany the standard.
