xpath - how to select multiple nodes based on value

I have some xml and I would like to dynamically extract some information, based on some incoming data.

Here is some xml:

<?xml version="1.0" encoding="UTF-8"?>
<releaseNote>
 <name>DECOUPLING_client</name>
  <change>
   <date hour="12" day="24" second="44" year="2012" month="10" minute="46"/>
   <submitter>Automatically Generated</submitter>
   <description>ReleaseNote Created</description>
  </change>
  <change>
   <version>0-2</version>
   <date hour="12" day="24" second="48" year="2012" month="11" minute="46"/>
   <submitter>fred.darwin</submitter>
   <description> first iteration of decoupling client - copied files from old decoupling module</description>
   <install/>
  </change>
 <change>
  <version>0-3</version>
  <date hour="16" day="25" second="34" year="2012" month="11" minute="52"/>
  <submitter>fred.darwin</submitter>
  <description> promoting changes</description>
  <install/>
 </change>
</releaseNote>

And I'd like to pass in the string '0-2' and find out all versions since 0-2 like this:

0-3     fred.darwin       25/11/2012      promoting changes

It's complicated by the fact that the numbers I'm comparing start with '0-'.

However luckily you can remove the '0-' and get a real number, which corresponds to a position, so I've got as far as something like this:

xmllint --xpath '/releaseNote/change[position()>2]/description/text() ${file}

which just concatenates all the descriptions and spits them out.

How do I loop through them and select multiple node content?
