Function within an expression
Is it possible to do a function inside of an expression? Here is my XSL code: <xsl:for-each select="$lines"> <record> <xsl:apply-templates select="$field_definitions/*[@type = (substring(., 1, 3))]"> <xsl:sort select="field_no" order="ascending" data-type="number"/> <xsl:with-param name="current_context" select="."/> </xsl:apply-templates> </record> </xsl:for-each> My question is in regards to the substring function in the apply-templates expression. The current context of the $lines variable will look something like this: "AA0 12345 fdsajl129..." I'm trying to match the first three characters of that string. If I can't do this, can I create a variable for this for-each ONLY? Thanks again, Jim neff
