Hi. I'm writing a 2.0 stylesheet and my processor is Saxon HE 9.2.1.1. Also, I'm just starting out with XSLT. There are two problems there, one is that patterns use a restricted syntax compared to xpath, but more importantly parameters and variables in xpath hold _values_ (as they would in c or fortran) not fragments of syntax 9as they would in a shell scripting language) so when you go <xsl:with-param name="starting-element" select = "h1" /> the parameter does not hold the fragment of a pattern "h1" it holds the result of ebaluating teh expression h1 at that point, which is a possibly empty sequence of h1 nodes. the this works <xsl:for-each select = "$starting-element"> but it is not (at that point) selecting h1 elements it is simply iterating over the list of elements that has already been selected and stored in the $starting-element variable. but this could not work even if it were not a syntax error <xsl:for-each-group select = "*" group-starting-with = "$starting-element"> the grouping attributes need to take patterns or expressions used to filter the nodes selected, not take a sequence of nodes. so do not pass in a sequence of nodes, pass in a string: <xsl:with-param name="starting-element" select = "'h1'" /> (note the extra quotes( then you can use that string in a pattern
