Wrap the whole thing inside a variable. <xsl:variable name="str"> <xsl:call-template name="add-data"/> </xsl:variable> <xsl:template name="add-data"> <xsl:param name="strlen" select="0"/> <xsl:param name="index" select="1"/> <xsl:if test="strlen < 915"> <xsl:value-of select="DATA[$index]"/> </xsl:if> <xsl:if test="$index <= count(DATA)"> <xsl:call-template name="add-data"> <xsl:with-param name="strlen" select="$strlen+string-length(DATA[$index])"/> <xsl:with-param name="index" select="$index+1"/> </xsl:call-template> <xsl:if> </xsl:template> (Untested, and probably not exactly what you want when, e.g., the first DATA node has more than 915 characters, but you get the idea) Steve XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
