The problem is, if you have:

<xsl:template match="/html/body">
  ...
</xsl:template>

then the default template will be applied to all the nodes that aren't part of 
/html/body.  The default template is to copy text nodes and ignore everything 
else, so that might explain your problem.

Instead of changing select to select="node()" and match="/html/body", you 
should try,

<xsl:template match="/">
  <xsl:copy-of select="html/body/node()"/>
</xsl:template>

If that doesn't work, then I don't know what's wrong.

An alternative to using copy-of is to use the "identity template", which can 
look something like this (untested):

<!-- ignore all nodes unless otherwise specified -->
<xsl:template match="node()" priority="0"/>

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

You might want to go this route if you ever want to apply other templates to 
specific elements in the /html/body//* tree.  Using xsl:copy-of doesn't allow 
you to modify the output of the copy with other templates.  If you don't 
think you'll ever need to apply other templates, then copy-of should work 
fine.
