Re: Parsing copy-of result tree fragment

You don't. Once you have used xsl:copy-of, you have put a copy of a branch
of the source tree into the result tree. You never had the opportunity to
change anything before it went into the result tree.

With pure XSLT 1.0, the solution involves using xsl:copy. xsl:copy works
like xsl:copy-of, but only copies the current node. The contents of the
xsl:copy element are used to generate the rest of the descendants of the
copied node.

<xsl:template match="sub-data">
  <xsl:copy>
    <xsl:apply-templates select="node()|@*" mode="copying"/>
  </xsl:copy>
</xsl:template>

<xsl:template match="text()" mode="copying">

    <xsl:with-param name="stringIn" select="."/>
    <xsl:with-param name="substringIn">'</xsl:with-param>
    <xsl:with-param name="substringOut">\'</xsl:with-param>
  </xsl:call-template>
</xsl:template>

<xsl:template name="SubstringReplace">
   <xsl:param name="stringIn"/>
   <xsl:param name="substringIn"/>
   <xsl:param name="substringOut"/>
   <xsl:choose>
      <xsl:when test="contains($stringIn,$substringIn)">
