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.
