Your best bet is to write a shell-script that creates an XML file
index.xml of the form
<index>
<d>name001.xml</d>
<d>name002.xml</d>
etc
</index>

and then your transformation is simply:

<xsl:template match="/">
  <big-doc>
  <xsl:copy-of select="document(/index/d)"/>
  </big-doc>
</xsl:template>

You will need a lot of memory. Doing it with SAX would be much more
efficient.
