Re: Comments in XPath / XSLT regular expressions?

   I came up with the following as a best-practice for 
  ourselves:

  <xsl:variable name="re-extract-filename" >
    ^.*?              <!-- non-greedy: grab everything -->  

probably worth adding an as="xs:string" to the xsl:variable line, so the
variable stores a string, as otherwise saxon will go to the trouble of
generating a new document node with a unique identity, with a child text
node with value your regex, and then when you use it as
$re-extract-filename it'll have to coerce it back to a string anyway.
