RE: [xsl] Complex XPath Expression

Thanks for the tip Michael. Oh but darn it, I just downloaded this app called Visual XPath and it does not like the current() function. (It will be Tuesday before I test this in code with MSXML parser). Does anyone recommend a free XSL XPath visualizer app?

Try replacing recordset[] with current()/recordset[].
