xml - XSLT to remove an Element's Value

Question

I need to remove a value from an element, but preserve the element itself in the output XML as an empty element.

My input file:

<a>
    <b>TEXT1
        <c>123</c>
        <d>qwe</d>
        <e>rty</e>
    </b>
    <b>TEXT2
    <c>345</c>
    <d>iop</d>
    <e>jkl</e>
    </b>
</a>

The output file should retain element c, but the numbers in the element should be gone.

<a>
<b>TEXT1
    <c></c>
    <d>qwe</d>
    <e>rty</e>
</b>
<b>TEXT2
    <c></c>
    <d>iop</d>
    <e>jkl</e>
</b>
</a>

Answer 1

Even simpler/shorter:

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

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

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