XPath Get first element of subset

Question

I have XML like this:

    
        
        
    &         


        

Answer 1

I want to get first element. But with XPath expression //*/CCC[1] I have got two elements. Each of them is the first elemet in context. How to get first element in subset?

This is a FAQ:

The [] operator has a higher precedence (binds stronger) than the // abbreviation.

Use:

(//CCC)[1]

This selects the first (in document order) CCC element in the XML document.
