Hi Dan, >Finally, I am not sure I agree with another reply with regard >to merging of text nodes.

You are right of course - I just checked the spec. Adjacent text nodes get merged in result tree fragments, not node sets. For example, <xsl:variable name="set1"> <xsl:for-each select="set1/text()"> <xsl:value-of select="."/> </xsl:for-each> </xsl:variable> <xsl:value-of select="count($set1/text())"/> might seem a clumsier way of doing the same thing, but in fact gets you one node not four. (Only works post XSLT 1.0 too - it converts an RTF to a node set). Regards, Trevor Nash XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
