Question

I have this XML file:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<results>
  <output>
    <status>OK</status>
    <usage>Please use it</usage>
    <url/>
    <language>english</language>
    <category>science_technology</category>
    <score>0.838661</score>
  </output>
</results>

I want to remove the tags <output> </output> from this XML.

OUTPUT EXPECTED

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
 <results>
 <status>OK</status>
    <usage>Please use it</usage>
    <url/>
    <language>english</language>
    <category>science_technology</category>
    <score>0.838661</score>

</results>

How can I do this?

Answer 1

Shortest as possible:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

    <xsl:template match="results">
     <xsl:copy>
       <xsl:copy-of select="output/*"/>
     </xsl:copy>
    </xsl:template>

</xsl:stylesheet>

or using identity rule:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

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

    <xsl:template match="results">
        <xsl:copy>
            <xsl:apply-templates select="output/*"/>
        </xsl:copy>
    </xsl:template>

</xsl:stylesheet>
