Your solution does work for me though, I've had to modify it slightly because my real document allows nesting of text level elements . This means that I have to propagate the $dif parameter through all my text level elements templates, (not ideal but better than having two versions of each with a different mode), so using a modified version of my sample and your suggestion this is the result <!-- input document note in this one the span element is nested in a i element ---> <doc> <textlevel id="textlevel1"> <i>text text text</i> <i><span id="s1">text <i>text</i> text</span></i> text text <b>text</b> </textlevel> </doc> <!-- xsl file note that //span //i //b all take the dif param and call apply-templates with this param --> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xalan="http://xml.apache.org/xalan" exclude-result-prefixes="xalan" version="1.0"> <xsl:template match="/"> <resultdoc> <newstructure_e1> <xsl:apply-templates select="doc/textlevel[@id='textlevel1']"> <xsl:with-param name="dif" select="concat(generate-id(),'-a')" /> </xsl:apply-templates> </newstructure_e1> <newstructure_e2> <xsl:apply-templates select="doc/textlevel[@id='textlevel1']"> <xsl:with-param name="dif" select="concat(generate-id(),'-b')" /> </xsl:apply-templates> </newstructure_e2> </resultdoc> </xsl:template> <xsl:template match="doc/textlevel"> <xsl:param name="dif" /> <textlevel> <xsl:apply-templates > <xsl:with-param name="dif" select="concat(generate-id(),$dif)" /> </xsl:apply-templates> </textlevel> </xsl:template> <xsl:template match="//span"> <xsl:param name="dif" /> <NEWspan> <xsl:attribute name="id"> <xsl:value-of select="$dif"/> </xsl:attribute> <xsl:apply-templates> <xsl:with-param name="dif" select="$dif" /> </xsl:apply-templates> </NEWspan> </xsl:template> <xsl:template match="i"> <xsl:param name="dif" /> <NEWi> <xsl:apply-templates> <xsl:with-param name="dif" select="$dif" /> </xsl:apply-templates> </NEWi> </xsl:template> <xsl:template match="b"> <xsl:param name="dif" /> <NEWb> <xsl:apply-templates> <xsl:with-param name="dif" select="$dif" /> </xsl:apply-templates> </NEWb> </xsl:template> </xsl:stylesheet> <!-- resulting output --> <?xml version="1.0" encoding="UTF-8"?> <resultdoc> <newstructure_e1><textlevel> <NEWi>text text text</NEWi> <NEWi><NEWspan id="N10004N10000-a">text <NEWi>text</NEWi> text</NEWspan></NEWi> text text <NEWb>text</NEWb> </textlevel></newstructure_e1> <newstructure_e2><textlevel> <NEWi>text text text</NEWi> <NEWi><NEWspan id="N10004N10000-b">text <NEWi>text</NEWi> text</NEWspan></NEWi> text text <NEWb>text</NEWb> </textlevel></newstructure_e2> </resultdoc> Thanks a lot for you help, Cheers, Dave. > This XSL: > > <xsl:template match="/"> > <resultdoc> > <newstructure_e1> > <xsl:apply-templates select="doc/textlevel[@id='textlevel1']"> > <xsl:with-param name="dif" select="concat(generate-id(),'-a')" /> > </xsl:apply-templates> > </newstructure_e1> > <newstructure_e2> > <xsl:apply-templates select="doc/textlevel[@id='textlevel1']"> > <xsl:with-param name="dif" select="concat(generate-id(),'-b')" /> > </xsl:apply-templates> > </newstructure_e2> > </resultdoc> > </xsl:template> > > <xsl:template match="doc/textlevel"> > <xsl:param name="dif" /> > <textlevel> > <xsl:apply-templates > > <xsl:with-param name="dif" select="concat(generate-id(),$dif)" /> > </xsl:apply-templates> > </textlevel> > </xsl:template> > > <xsl:template match="//span"> > <xsl:param name="dif" /> > <NEWspan> > <xsl:attribute name="id"> > <xsl:value-of select="$dif"/> > </xsl:attribute> > </NEWspan> > </xsl:template> > > <xsl:template match="i"> > <NEWi> > <xsl:value-of select="."/> > </NEWi> > </xsl:template> > > <xsl:template match="b"> > <NEWb> > <xsl:value-of select="."/> > </NEWb> > </xsl:template> > > Produces this result (which is what I think you asked for): > > <resultdoc> > <newstructure_e1> > <textlevel> > <NEWi>text text text</NEWi> > <NEWspan id="d0e2d0-a"/> text text > <NEWb>text</NEWb> > </textlevel> > </newstructure_e1> > <newstructure_e2> > <textlevel> > <NEWi>text text text</NEWi> > <NEWspan id="d0e2d0-b"/> text text > <NEWb>text</NEWb> > </textlevel> > </newstructure_e2> > </resultdoc> > > > > Good luck, > > Bryan -- Dr. David Holden.
