Transform node parts and paste rest

Question

Hi,
its difficult to explain what I need. Heres an example:
XML:
<DOCUMENT>
  <PAGE>
    <PAGEHEADER type="1">
    </PAGEHEADER>
    <block>Hello</block>
    <block>World</block>
    <line>This is a test</line>
    <GREETING type="2">
    </GREETING>
  </PAGE>
</DOCUMENT>Output:
<DOCUMENT>
  <PAGE>
    <PAGEHEADER type="1">
    </PAGEHEADER>
    <block>Hello</block>
    <block>World</block>
    <line>This is a test</line>
    <GREETING type="2">
    </GREETING>
  </PAGE>
</DOCUMENT>There are several standard subnodes for PAGE: PAGEHEADER, GREETING, ...
Its not a problem to transform these nodes, but I want all non standard nodes (block, line, ...) under PAGE unchanged in the output xml.
XSL:
<xsl:output method="xml"/>
<xsl:stylesheet>
  <xsl:template match="/">
    <DOCUMENT>
      <xsl:apply-templates/>
    </DOCUMENT>
  </xsl:template>
  <xsl:template match="PAGE">
    <PAGE>
      <xsl:apply-templates/>
    </PAGE>
  </xsl:template>
  <xsl:template match="PAGEHEADER">
  </xsl:template>
  <xsl:template match="GREETING">
  </xsl:template>
  <xsl:template match="?? non standard nodes ??">
  </xsl:template>
</xsl:stylesheet>Is it possible?
Thanks for reply

Is it possible?Sure, that's a classic ;)
Use a stylesheet based on the identity transformation, and add specific templates to process the nodes you want :
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml"/>
  <xsl:template match="node()|@*">
    <xsl:copy>
      <xsl:apply-templates select="node()|@*"/>
    </xsl:copy>
  </xsl:template>
  <xsl:template match="PAGEHEADER">
    <xsl:copy>
      <xsl:apply-templates select="@*"/>
      <!-- add PAGEHEADER children here -->
    </xsl:copy>
  </xsl:template>
  <xsl:template match="GREETING">
    <xsl:copy>
      <xsl:apply-templates select="@*"/>
      <!-- add GREETING children here -->
    </xsl:copy>
  </xsl:template>
</xsl:stylesheet>For example :
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml"/>
  <xsl:template match="node()|@*">
    <xsl:copy>
      <xsl:apply-templates select="node()|@*"/>
    </xsl:copy>
  </xsl:template>
  <xsl:template match="PAGEHEADER">
    <xsl:copy>
      <xsl:apply-templates select="@*"/>
      <PAGEHEADER_CHILD></PAGEHEADER_CHILD>
    </xsl:copy>
  </xsl:template>
  <xsl:template match="GREETING">
    <xsl:copy>
      <xsl:apply-templates select="@*"/>
      <GREETING_CHILD></GREETING_CHILD>
    </xsl:copy>
  </xsl:template>
</xsl:stylesheet>will produce :
<?xml version="1.0" encoding="UTF-8"?>
<DOCUMENT>
  <PAGE>
      <PAGEHEADER type="1">
         <PAGEHEADER_CHILD/>
      </PAGEHEADER>
      <block>Hello</block>
      <block>World</block>
      <line>This is a test</line>
      <GREETING type="2">
         <GREETING_CHILD/>
      </GREETING>
  </PAGE>
</DOCUMENT>
