Just ignoring the numbers for a moment. I was thinking last night that it would be possible to write a stylesheet that when applied to a stylesheet, generates a "debug" version of that stylesheet which contains <xsl:message> elements which print out things like template calls and parameters received. I'm sure it can be done but I'd hate to have to deal with all of the namespace bollox. Here's the kind of code that you might use for named templates - definitely not tested. Let's say that we use oxsl as the output XSL namespace, and use namespace-alias for the switch. <xsl:template match="xsl:template[@name]"> <xsl:copy> <xsl:copy-of select="@*" /> <xsl:copy-of select="xsl:param" /> <oxsl:message> <oxsl:value-of select="'Entering template [{@name}]
'" /> <oxsl:value-of select="concat(' current node = [', name(), ']
')" /> <xsl:for-each select="xsl:param"> <oxsl:value-of select="concat(' parameter [{@name}]=[', ${@name}, ']
')" /> </xsl:for-each> </oxsl:message> <xsl:copy-of select="*[not(self::xsl:param)]" /> </xsl:copy> </xsl:template> -- Warren Hedley Department of Engineering Science Auckland University New Zealand XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
