I have the following need:
given a complicated XML source, I have to change in output the text
element for same nodes maintaining the source structure.
An example can be this in which I want to change the <elem2> text
values, present in different levels.
...
I'm trying to use the following XSL script

===================== XSLT =====================
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:msxsl="urn:schemas-microsoft-com:xslt"
exclude-result-prefixes="msxsl">

<xsl:output method="xml" indent="yes"/>

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

  <xsl:template match="@*|node()">
    <xsl:choose>
      <xsl:when test="elem2">
        <elem2>NEW ELEM</elem2>

The strange thing (for me) is that, if I substitude the <choose> block
with the <otherwise> code, I obtain a result tree identical to source
tree.

===================== SIMPLIFIED XSLT =======================
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:msxsl="urn:schemas-microsoft-com:xslt"
exclude-result-prefixes="msxsl">

<xsl:output method="xml" indent="yes"/>

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

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

<xsl:template match="elem2">
  <elem2>NEW ELEM</elem2>
</xsl:template>

</xsl:stylesheet>
=========================================================

Obviously, in this way I cannot chack the node name for set the
appropriate value.

Could you help me?
