Wrap group of XML nodes

Question

Im working with PHP5, and I need to transform XML in the following form:

    some text
    

        

Answer 1

You didn't address this in the original question, so it may not be required. But if the input has multiple sequences of elements that need to be wrapped, that are separated from each other by other sibling elements, e.g.:

    some text
    
        some text
        some text          
        some text
        some text
        some text          
    

the earlier answers will, I believe, lump the elements together, changing their order:

    some text
    
         
            some text
            some text          
            some text
            some text
         
        some text
    
 

Do you want that, or do you want to wrap them separately, like this?

    some text
    
         
            some text
            some text          
         
        some text
         
            some text
            some text
         
    
 

If the latter, it will probably be easiest to use an XSLT 2.0 construction. I don't know whether PHP 5 has XSLT 2.0 available, but if you can use such a thing, see this good article.
