RE: Conditional extraction of data
Yeah. This neatly sums up the problems I've been having. An XPath expression always seems to return an entire sub-tree, and it seems to me that I just want a single node in this case. Will xsl-copy give me that?

As both sub elements <bar> and <p> are _inside_ element <foo>, their textual content is returned as well. The output is therefore: " this is the value of foo this is the value of bar.this is the value of a paragraph that is the child of bar " (including new-lines when white-space is preserved) > <xsl:copy-of select="foo"/> will output a copy of all the text elements > as well as the elements and there values that are descendants of foo. > > Sorry for the confusion! > > <M:D/> Grtz, Geert
