Where are the 'duplicates' you speak of? Sorry, in my effort to be concise I apparently went overboard :-) Input I: <a><b><c>42</c></b></a> Input II: <a></a> Output (from either input): <a><b><c>foo</c></b></a> The "duplicates" I spoke of would be elements, or perhaps more correctly put, branches of the result tree. The example above would be accomplished by an XSLT implementing "add a tag /a/b/c with value 'foo'" "a/b/c" then is just my XPathish shorthand for an element and its context. This shorthand is necessary, as the implementation will itself be the result of applying a transform to an XML doc that "defines" a modification such as this. It is trivial to modify (via a template match) ala Input I or to add a new element (via xsl:copy and xsl:element) as in Input II. No amount of contortion, though, has led to a solution that works for both of the inputs above. I either fail to create the needed new elements to input II above, or end up "duplicating" a branch in Input I (e.g. returning <a> <b><c>42</c></b> <b><c>foo</c></b> </a>) My attempts thus far have been able to satisfy simple examples (including this one) but then fail in further testing (e.g. when trying to implement "add a tag a/b") I haven't provided sample code because I'm afraid I'd only further cloud the issue. Please let me know if anyone would rather debug :-) Thanks, Hans Gerwitz hans @ phobia . com XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
