Hi

I'm just starting out with XSL so please bear with me.

I have an XML file in the following format:

<PileCoords>
<Pile>
<PileNo>22</PileNo>
<Eastings>57.7981568796959</Eastings>
<Northings>166.059281023945</Northings>
</Pile>
<Pile>
<PileNo>21</PileNo>
<Eastings>57.7981568796959</Eastings>
<Northings>161.461817940551</Northings>
</Pile>
<Pile>
<PileNo>194</PileNo>
<Eastings>68.6908869290537</Eastings>
<Northings>167.952353915529</Northings>
</Pile>
<Pile>
<PileNo>4</PileNo>
<Eastings>83.9813040551062</Eastings>
<Northings>167.952353915529</Northings>
</Pile>
</PileCoords>

I would like to sort it by the PileNo element & keep it in XML format.
I've seen many examples where it's transformed to another format but 
very few to keep it as XML.

In this example: http://www.zvon.org/xxl/XSL-Ref/Tutorials/Sorting/so5.html
The element is explicitly defined in the template. Is this essential?
It would work in this case where I know all the elements names (eg 
PileNo, Eastings Northings etc) but what if they'd varied in number & names?

Is there a way to say 'copy all the elements under Pile regardless of 
what they're called'?

I hope I've used clear terminology.

Any help to find a solution would be greatly appreciated.

Thanks
Dave F.
