How do i do concat more than one tag value in vtd XML?

Question

How do I concatenate multiple tag values using XPATH on vtd XML?

  <pre>
      <a>
        <b>
           <c>Hi</c>  
           <d>Vtd</d>
           <e>Users</e>
        </b>
      </a>
  </pre>

I have tried to use the following unsuccessfully.

    Xpath: concat(\a\b\c, \a\b\d, \a\b\e)   Result is : Hi Vtd Users

If I use concat with this XPATH, I receive the following error:

    Error "Function Expr can't eval to node set"

You need to make sure that you are starting from the root node and that your axes are correct. The below XPath returns the desired output.

concat(pre/a/b/c, " ", pre/a/b/d, " ", pre/a/b/e)

@Bhuvanesh the above answer is sample xpath code. Is that what you mean by "Please send that Sample code"? – Ryan Gates Nov 19 '12 at 19:25
