[TxMt] way to make a certain file edit as an xml

[shawn bright]

hello all,
i do a lot of work with python and gtk. the builder file is written as
a .glade file, which is xml.
Is there a way that when i edit a .glade file in textmate, i can have
textmate treat the file as if it is an .xml file?

thanks,
shawn

great editor you guys have here by the way. much worth the coin.
