complicated sort problem

Similar problem with the one I had yesterday:
I need to sort the following xml:

<list>
    <file>file1.xml</file>
    <file>file2.xml</file>
......
    <file>file100.xml</file>
</list>

each of these files have some tags (2 of which are:)
    <date>20071805101800</date>(yyyymmddhhmmss)
    <url>folderX/foldery/</url>

So I need to sort the first xml by the date (which is in each fileX.xml). Is that possible? 10x
