Hi, The following xslt 1.0 stylesheet should work with a little tweaking. If there is an easier way to do this in 1.0, Iam not aware of it. probably much easier in xslt 2.0. <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="xml" indent="yes" /> <xsl:template match="/root"> <xsl:apply-templates select="statement-message[1]" mode="wrap"/> </xsl:template> <xsl:template match="statement-message" mode="wrap"> <xsl:apply-templates select="following-sibling::*[1][self::statement-message][not(string-length(following-sibling::*[self::statement-message]) = 0)][1]" mode="nowrap"> <xsl:with-param name="parent" select="."/> <xsl:with-param name="dotag" select="0"/> </xsl:apply-templates> <!-- <xsl:apply-templates select="following-sibling::*[1][self::statement-message]" mode="nowrap"/> --> </xsl:template> <xsl:template match="statement-message[. = '']"> <xsl:value-of select="'here'"/> <xsl:apply-templates select="following-sibling::*[1][self::statement-message]" mode="wrap"/> </xsl:template> <xsl:template match="statement-message" mode="nowrap"> <xsl:param name="parent"/> <xsl:param name="dotag"/> <xsl:choose> <xsl:when test="number($dotag) = 0"> <statement-message> <xsl:value-of select="$parent"/> <xsl:value-of select="."/> <xsl:choose> <!-- <xsl:when test="not(string-length(following-sibling::*[self::statement-message][1]) = 0)"> --> <xsl:when test="not(string-length(.) = 0)"> <xsl:apply-templates select="following-sibling::*[self::statement-message][not(string-length(following-sibling::*[self::statement-message]) = 0)][1]" mode="nowrap"> <xsl:with-param name="parent" select="."/> <xsl:param name="dotag" select="1"/> </xsl:apply-templates> </xsl:when> <xsl:otherwise> <xsl:apply-templates select="statement-message"/> </xsl:otherwise> </xsl:choose> </statement-message> </xsl:when> <xsl:otherwise> <xsl:value-of select="."/> <xsl:apply-templates select="following-sibling::*[self::statement-message][not(string-length(following-sibling::*[self::statement-message]) = 0)][1]" mode="nowrap"/> </xsl:otherwise> </xsl:choose> <xsl:choose> <xsl:when test="string-length(following-sibling::*[self::statement-message][1]) = 0"> <xsl:apply-templates select="following-sibling::*[1][self::statement-message]" mode="wrap"/> </xsl:when> </xsl:choose> <!-- <xsl:apply-templates select="following-sibling::*[self::statement-message][not(string-length(following-sibling::*[self::statement-message]) = 0)][1]" mode="wrap"/> --> </xsl:template> <xsl:template match="statement-message[. = '']"> <xsl:value-of select="'here'"/> <xsl:apply-templates select="following-sibling::*[1][self::statement-message]" mode="wrap"/> </xsl:template> </xsl:stylesheet> Hope this helps.

On the face of it a really easy problem. I have a bunch of elements like so: <statement-message>Your account is now seriously in arrears. To</statement-message> <statement-message>avoid further action a payment of</statement-message> <statement-message>$82.00 is required immediately. Any</statement-message> <statement-message>purchases will now be declined.</statement-message> <statement-message> </statement-message> <statement-message> More text </statement-message> <statement-message> </statement-message> <statement-message> </statement-message> <statement-message> </statement-message> I want to strip out the empty tags and merge adjacent elements as follows: <statement-message> Your account is now seriously in arrears. To avoid further action a payment of 82.00 is required immediately. Any purchases will now be declined.</statement-message> <statement-message> More text </statement-message> My code at the moment is: <xsl:for-each-group select="statement-message" group-ending-with="statement-message[string-length(normalize-space(follo wing-sibling::statement-message[1]))=0]"> <statement-message> <xsl:value-of select="."/> </statement-message> </xsl:for-each-group> My understanding of this is that it should start grouping from the 1st statement message, with the groups ending as soon as an empty element is reached. The empty tags at the end would still be there, but at least it should do the merge. However, the result looks like: <statement-message>Your account is now seriously in arrears. To</statement-message> <statement-message> </statement-message> <statement-message> More text </statement-message> <statement-message> </statement-message> <statement-message> </statement-message> <statement-message> </statement-message> So where am I going wrong?
