Would you please give me more clues as to which parts
that you cannot understand.
:-) It took me a while to figure out what Gavin meant...
In Gavins psuedo code above
"when" represents <xsl:when test="@starts-with='true'">
"otherwise" represents the following <xsl:otherwise>
"if test = x" represents <xsl:if test="starts-with($path, @pattern)">
"if test = y" represents <xsl:if test="contains($path, @pattern)">
"z" represents everything inside the above <xsl:if> statements
The bit of XSL this refers to is copied below.
