The following appears to work: <?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:output method="text"/> <xsl:strip-space elements="*"/> <xsl:template match="/"> <xsl:value-of select="string-length(child::*[1])"/> </xsl:template> </xsl:stylesheet> ///Peter ======= That solution confuses me - I would have expected descendants to work, rather than child::*[1]. <xsl:value-of select="string-length(descendants)"/> Can somebody comment on what is happening in this line?
