Populate XML template-file from XPath Expressions?

Question

What would be the best way to populate (or generate) an XML template-file from a mapping of XPath expressions?

The requirements are that we will need to start with a

Answer 1

This transformation creates from the "expressions" an XML document that has the structure of the wanted result -- it remains to transform this result into the final result:

 

 
    1
    bar
    foo
    00.00
    USD
    11.11
    AUD
    2
    some name
    some description
    00.01
    USD
 

 
  
 

 
  

  
    
     
       
         

          
        
       
       
        
       
     
     
  
 

When this transformation is applied on any XML document (not used), the result is:

   

      1
      bar
      foo
      
         00.00
         USD
      
      
         11.11
         AUD
      
   
   

      2
      some name
      some description
      
         00.01
         USD
      
   

Note:

1. You need to transform the "expressions" you are given into the format used in this transformation -- this is easy and straightforward.

2. In the final transformation you need to copy every node "as-is" (using the identity rule), with the exception that the top node should be generated in the "http://predic8.com/wsdl/material/ArticleService/1/" namespace. Note that the other namespaces present in the "template" are not used and can be safely ommitted.
