Hi All,

I am trying to write a script for parsing the xml content below:

set doc [dom parse $xml]
set root [$doc documentElement]

After this if i want to select nodes how can i give path for getting
CBI:sourceAddress?
Can someone plz help me on this?
Also to some useful tutorials on tdom package.

See:
http://wiki.tcl.tk/1948

especially the example on that page "XPath Query with namespaces".
