XSLT has three solutions though so you just need to implement one of those in your language 1) an additional xpath function, current() "//info[id = current()]" see http://www.w3.org/TR/xslt#function-current 2) The ability to bind XPath variables in the host language <xsl:variable name="here" select="."/> .... select="//info[id = $here]" 3) Implement (at least parts of) XPath2 to allow variable binding within XPath. select="for $here in . return //info[id = $here]" David ________________________________________________________________________ This e-mail has been scanned for all viruses by Star.
