Converting XML to escaped text in XSLT

Question

How can I convert the following XML to an escaped text using XSLT?

Answer 1

instead of escaping you can add the text inside a CDATA section. Text inside a CDATA section will be ignored by the parser, similar to if it was escaped.

your example would look like this

<TestElement>
<![CDATA[
<abc>
  <def ghi="jkl">
    mnop
  </def>
</abc>
]]>
</TestElement>

using following XSLT snippet:

<xsl:text disable-output-escaping="yes">&lt;![CDATA[</xsl:text>
 <xsl:copy-of select="/"/>
 <xsl:text disable-output-escaping="yes">]]</xsl:text>
 <xsl:text disable-output-escaping="yes">&gt;</xsl:text>

Answer 2

Do you need to use XSLT? Because, for reasons explained by Pavel Minaev, it would be much simpler to use another tool. An example with xmlstartlet:

% xmlstarlet escape
<?xml version="1.0" encoding="utf-8"?>
<abc>
  <def ghi="jkl">
    mnop
  </def>
</abc>
[Control-D]
&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;abc&gt;
  &lt;def ghi="jkl"&gt;
    mnop
  &lt;/def&gt;
&lt;/abc&gt;
