XSLT: Replacing “__” with this character “:”

问题:

Below is input XML code and I want to replace wherever this __ character sequence is mentioned it to be replaced by a colon : character.

For example, if it is sbdh__sender, it should be replace by sbdh:sender.

Any help on this will be appreciated.
