Copy all elements of a namespace and nothing else

Question

We have a bunch of files that are html pages but which contain additional xml elements (all prefixed with our company name \'TLA\') to provide data and structure for an older pr

Answer 1

You could try something like this...

XSLT 1.0

<xsl:stylesheet version="1.0" xmlns:tla="http://www.tla.com" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output indent="yes"/>
    <xsl:strip-space elements="*"/>

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

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

</xsl:stylesheet>

Answer 2

This should do it:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:tla="http://www.tla.com">
  <xsl:output method="xml" indent="yes" omit-xml-declaration="yes" />
  <xsl:strip-space elements="*" />

  <xsl:template match="text()" />

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

When run on your sample input (once the missing namespace declaration is added), the result is:

<TLA:document xmlns:TLA="http://www.tla.com">
  <TLA:contexts>
    <TLA:context id="id_1" value="" />
  </TLA:contexts>
  <TLA:page>
    <TLA:question id="q_id_1" />
  </TLA:page>
</TLA:document>
