Checking the level of the element

[maspero]

Hi,

first a definition of what i call a level :

if you have an xml file like that :

<ScannerSet>
      <Section name="Computer safety">
              <Scanner name="Virus Scan" progID="Mic" />
      </Section>
</ScannerSet>
<PrintSet>
      <Section name="blabla">
              <Print name="Vbakfdsqf" progID="qsdqsd" />
      </Section>
</PrintSet>

ScannerSet = level 1
Section = level 2
Scanner = level 3
etc...

I was wondering if it possible to get all the elements of one particular level :

For example " give me all the level 3 !!!"
returns :
<Scanner name="Virus Scan" progID="Mic" />
<Print name="Vbakfdsqf" progID="qsdqsd" />

Thx
