    You have (at least) two problems:

    1. The default namespaces are different, so the template matches in the XSL won’t work. Either make them match or provide explicit namespace prefixes in the stylesheet.
    2. The value-of-select will return the text value of the body element, which is probably not what you want.

    If all you’re trying to accomplish is to output the SVG part as an SVG doctype, then do the following:

    1. Google “XSL Identity Transform” to understand how to do a “deep copy” from the input to the output.
    2. Add an <xsl:output ...> tag with doctype-public and doctype-system attributes specifying the doctype information you want output.

    This is untested, but should be pretty close. You’ll have to add the doctype info:

    <?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet 
  xmlns="http://www.w3.org/1999/xhtml"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
  xmlns:svg= "http://www.w3.org/2000/svg"
  version="2.0">

  <xsl:output method="xml" doctype-public="..." doctype-system="..."/>

  <xsl:template match="/">
    <xsl:apply-templates select="//svg:svg"/>    
  </xsl:template>

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

</xsl:stylesheet>
