Replace NameSpaces in XSLT

You may come across a situation where you want to replace one set of namespaces to another set. A typical example is that you have a pass-through OSB Service whose proxy is based on your Project’s namespaces and the underlying service is based on the out-of-the-box service namespaces.

In such cases, the following XSLT will search-replace the namespaces

For example, if your input xml looks like

   ..
   ..
   ..
   
      ..
      ..
      
        ..
        ..
      
      ..
    
    ..

and the response has to have a different set of namespaces,

   ..
   ..
   ..
   
      ..
      ..
      
        ..
        ..
      
      ..
    
    ..

The following XSLT works
