Wanted: All unique namespaces in a document
Hi, I'm trying to write an XSLT sheet extracting all unique namespaces used in a document. My processors of choice are Xalan 1.0.0 and SAXON, as current XT does not support the namespace:: axis. The results are, err, quite random. And I haven't tried Oracle yet :) (1) First attempt: <xsl:for-each select="//namespace::*"> <xsl:value-of select="."/> </xsl:for-each> In Xerces, this yields a namespace-uri for each element with an xmlns:foo attribute (including doublets). In SAXON it outputs many, many namespace-uri. I guess it may return all namespaces visible from each element. (2) Second attempt: <xsl:for-each select=" //* [not( namespace-uri(.) = namespace-uri(preceding::.))] "> <xsl:value-of select="namespace-uri(.)"/> </xsl:for-each> Fails in SAXON (illegal construct preceding::.). In Xerces it does not fail, and returns the namespace URI string for each element in the document. Anyone with a clue for a solution that (at least in theory) works ?
