Which processor are you using? Are you getting thrashing due to shortage of memory? If it takes this long on Saxon, then I'm interested to find out why. The repeated use of "node()[contains(name(), 'field')]" isn't particularly nice. It suggests poor design of the XML document if the fact that an element name contains a particular substring is so significant. You might be better off doing a preprocess of the document in which elements whose name contains 'field' are given an extra attribute, field="yes", and then use this attribute in the second phase. In any case, I suspect that you are not interested in all nodes whose name contains 'field', but only in elements whose name contains 'field'. Replacing "node()" by "*" will speed things up a bit. And incidentally, you never need to specify "//" at the start of a match pattern. Mike Kay XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
