What is the context in which you find you can’t?

Here’s a document:

<root>
  <branch>
    <A/>
    <A/>
    <B/>
    <B/>
    <C/>
    <C/>
  </branch>
  <alternate>
    <A/>
    <A/>
    <B/>
    <B/>
    <C/>
    <C/>
  </alternate>
</root>

Here’s a stylesheet:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
                xmlns:xs="http://www.w3.org/2001/XMLSchema";
                exclude-result-prefixes="xs"
                version="3.0">

<xsl:output method="xml" encoding="utf-8" indent="no"/>

<xsl:mode on-no-match="shallow-copy"/>

<xsl:template match="/">
  <xsl:apply-templates/>
</xsl:template>

<xsl:template match="(branch|alternate)/A">
  <xsl:copy>
    <m1/>
    <xsl:apply-templates/>
  </xsl:copy>
</xsl:template>

<xsl:template match="branch/(B|C)">
  <xsl:copy>
    <m2/>
    <xsl:apply-templates/>
  </xsl:copy>
</xsl:template>

</xsl:stylesheet>

And here’s what I get if I apply one to the other:

<?xml version="1.0" encoding="utf-8"?><root>
  <branch>
    <A><m1/></A>
    <A><m1/></A>
    <B><m2/></B>
    <B><m2/></B>
    <C><m2/></C>
    <C><m2/></C>
  </branch>
  <alternate>
    <A><m1/></A>
    <A><m1/></A>
    <B/>
    <B/>
    <C/>
    <C/>
  </alternate>
</root>

                                        Be seeing you,
                                          norm
