(:o Here's the transformation, which does what was initially intended: <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="text"/> <xsl:template match="*"> <xsl:variable name="vPrevText"> <x> <xsl:copy-of select="preceding::text()[contains(., '
')]"/> <xsl:for-each select="preceding::comment() [contains(., '
')]"> <xsl:value-of select="."/> </xsl:for-each> <xsl:for-each select="preceding::processing-instruction() [contains(., '
')]"> <xsl:value-of select="."/> </xsl:for-each> </x> </xsl:variable> <xsl:variable name="vLineNo" select="string-length($vPrevText) + 1 - string-length(translate($vPrevText, '
', ''))"/> <xsl:value-of select="concat(name(), ' : line ', $vLineNo, '
')"/> <xsl:apply-templates/> </xsl:template> <xsl:template match="node()[not(self::*)]"/> </xsl:stylesheet> It also takes care of multiline comments / processing-instructions. When applied on this source.xml: <root> <item>1</item> <!-- --> <!-- --> <item>5</item> <item>3</item> <item>2</item> <item>6</item> <item>4</item> </root> The result is: root : line 1 item : line 2 item : line 6 item : line 7 item : line 8 item : line 9 item : line 10 ===== Cheers, Dimitre Novatchev. http://fxsl.sourceforge.net/ -- the home of FXSL __________________________________________________ Do you Yahoo!?
