Applescript & xml

[Trillian]

is there anyway that I can get Applescript and xml to play nicely?

What I want is like if

<name>playpause</name> (or whatever the name command is for a object, I'm tired)

then Applescript tells "itunes"

using termes from application "iTunes"
tell application "iTunes"
play pause
end tell
end using terms from

any suggestions?
