Unable to append xml value as a child of XPATHNavigaotr, It just copies the strucutre and no value

Question

Hello

I have 2 XPathNavigators :

XPathNavigator a XPathNavigator b

In an inner loop i am assigiging values to "b" and then at the end of each iteration, I want to assing innerxml of "b" to the innerxml of "a";

a.InnerXML+=b.innerXML;

But when I do this, its just copying the xml strucure of b without values.

I even tried with appendChild() & setvalue() method. No Luck

Anybody has an idea about this?
