it seems like it is :)

Why are you using a select attribute? Why not just:

<xsl:template match="files">
  <select name="combo1" onchange="transformSelection(this.value)">
    <xsl:apply-templates mode="create-options"/>
  </select>
</xsl:template>

<!-- I would use the same elem name for 'files' children, but -->
<xsl:template match="*" mode="create-options">
  <option value="normalize-space(.)">
    <xsl:value-of select="."/>
  </option>
</xsl:template>

This will create the dropdown. Then, when running in the browser, the 
user selects an option and triggers the onChange event. You send the 
current value of the select to a javascript function that loads the file 
 and uses it as the XML source in a client-side transform. Use another 
XSL that works with this source. Place the result of the transform in 
some HTML div or what-have-you -- or rewrite the whole page if you need to.

Well, you can't communicate the onchange event to the transformation. 
You have to use javascript to communicate and setup another 
transformation. Hopefully what I wrote above makes sense.
