XSLT to add new elements to the root element of an XML

Question

I want to add a couple of elements at the end of an XML document, right before the closing of the root node, and I\'m using an XSL to do the transformation.

Try it this way?

    
        
    




    
        
        
        my content
    

If all you ever want to do is add the new element/s, then you could shorten this to:

    
        
        
        my content

Note:

In your example input, the root element - and by inheritance, all of its child nodes - is in a namespace. If you want the added element/s to be in the same namespace, use:

my content

instead of:

my content

Edit:

why doesn't it work if I put ( is the document root node) instead of ?

That too is the result of the root element being in a namespace. In order to address it by name, you need to assign a prefix to the namespace and use it in the XPpath expression selecting the node:

    
        
        
        my content   
    

Once you have defined the prefix, you can also use it to place the added element/s in the namespace bound to the prefix:

    
    my content   

Alternatively you could do:

    
    my content
