[mdlug] Need help with xmlstarlet

[Jeff Hanson]

I'm trying to query and change an attribute in an xml file with
xmlstarlet.  The xml file one I've been practicing with is
caledonia.xml from the "Caledonia KDM 1.0" theme file:
http://kde-look.org/content/show.php/Caledonia+KDM?content=143130

I'm trying to query and change the y positional attribute for the
"logo.png" pixmap.  The problem is that I don't know enough about xml
to create proper xmlstarlet syntax to do so.  I've been able to query
and change elements in gconf files but not attributes in this theme
file.

The xmlstarlet docs are at: http://xmlstar.sourceforge.net/doc/UG/
