[xsl] Group by parameter tag

[IZASKUN GUTIERREZ GUTIERREZ <igutierrez027@xxxxxxxxxxxxx>]

Hello everybody!

I have this .xml file:

<?xml version="1.0" encoding="windows-1252"?>
<file xmlns="http://bibtexml.sf.net/";>

  <entry id="art">
    <article>
      <author>Isabel Menindez and Luis Perez</author>
      <note>note1</note>
      <note>note2</note>

      <title>The title</title>
      <note>note3</note>
      <note>note4</note>
    </book>
  </entry>

<entry id="inb">

    </inbook>
  </entry>

</file>


 I need one template (version 1.0 or 2.0) to group values of tags
note separated by "and" words, but I have a problem. Really, the tag I
must group by must come like parameter. This is, I dont know really
what is the name of the tag that I must group by.

The result must be:

<?xml version="1.0" encoding="windows-1252"?>
<file xmlns="http://bibtexml.sf.net/";>

  <entry id="art">
    <article>
      <author>Isabel Menindez and Luis Perez</author>

<entry id="boo">
    <book>
      <title>The title</title>
      <note>note3 and note4</note>
    </book>
  </entry>

<entry id="inb">
    <inbook>
      <pages>42</pages>
    </inbook>
  </entry>

</file>


Could anybody help me?

Thank You, Regards
