what is the meaning of colon in xml tags.

Answer 1

Colons in xml nodes denote a namespace. Its likely you will be able to parse your xml more easily with something like DOM or SimpleXML which both have support for namespaced nodes. There's a good article here which discusses simpleXML and namespaces.
