XMLList - find specific attribute

[mark goldin]

Let's say I have the following code:
<Project Name="Project1" ID="2293" attr1="1.00" attr2="2.00">
  <Subproject Name="Subproject1"/>
  <Subproject Name="Subproject2"/>
  <Subproject Name="Subproject3"/>
</Project>

I'd lit to find ID="2293" based on a fact that the element has both attr1
and attr2.

Thanks for help.
