Here, How to include two namespace to select AVResult ?

Answer 1

AVResult actually has three namespaces. It also takes on the namespace for its parent node AVResponse (xmlns="http://info.com/Contracts"). But, since the namespace for AVResponse does not have a prefix, you have to create a reference to it with a prefix in your stylesheet tag, which you already created as ns1. So, any time you want to reference AVResponse or any of it's child or grandchild nodes you have to use the ns1 prefix. Also, you can't put ns1 in exclude-result-prefixes and exclude it.
