Hello,=C2=A0

I have a postgresql database table with xml data.=C2=A0
What I need is a list of all elements and attributes.
Example:
<area>
  <sub>
   <sub2 attr=3D'1'>comment</sub2>
   <sub2 attr=3D'2'>comment</sub2>
  <sub>
</area>

The result should be:
/area
/area/sub
/area/sub/sub2
/area/sub/sub2@attr
/area/sub/sub2
/area/sub/sub2@attr

or distinct (it's enough)
/area
/area/sub
/area/sub/sub2
/area/sub/sub2@attr

Is there a postgresql function to build this list?

Franz
