Question

I want to globally rename every node in an XML element by appending the existing name with a suffix.

The current XSLT I wrote below works, but loses element values. How do I keep the values?

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:variable name="suffix" select="'_Ver1'"/>
<xsl:template match="node()">
    <xsl:element name="{concat(local-name(.), $suffix)}">
        <xsl:apply-templates select="@*|node()"/>
    </xsl:element>
</xsl:template>
</xsl:stylesheet>

Answer 1

It’s because node() also includes text nodes. If your input XML had any line-breaks, you may have noticed elements like <_Ver1/> in your output.

Try something like this instead:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output indent="yes"/>
  <xsl:variable name="suffix" select="'_Ver1'"/>

  <xsl:template match="text()">
    <xsl:copy>
      <xsl:apply-templates/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="*">
    <xsl:element name="{concat(name(.),$suffix)}">
      <xsl:copy-of select="@*"/>
      <xsl:apply-templates/>
    </xsl:element>
  </xsl:template>

</xsl:stylesheet>

I’ve added a template for text() and also a copy-of for any attributes that might be in the XML.
