RE: [xsl] Conditional selecting

["Michael Kay" <mike@xxxxxxxxxxxx>]

No directly relevant to your question, but in XSLT 1.0 this:

			<!-- number() makes sure we process field_no as a
number and not a string, otherwise 11 comes before 9 ;) -->
			<xsl:sort select="number(field_no)"
order="ascending"/>

doesn't do what the comment says. In 1.0 you get a string-based sort unless
you specify data-type="number", regardless whether the actual values are
numeric.
