Sorry Swathi, wasn't clear in my request.

I have xml data as below. I would like it so the user selects an item from a
description list box this then populates 3 other text boxes (price, per and
comments) with the data for that row.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Root>
    <External>
        <Description>Item1</Description>
        <Price>80.00</Price>
        <Per>m2</Per>
        <Comments>Fine</Comments>
    </External>
    <External>
        <Description>Item2</Description>
        <Price>350.00</Price>
        <Per>ea</Per>
        <Comments>Blue</Comments>
    </External>
    <External>
        <Description>Item3</Description>
        <Price>972.00</Price>
        <Per>ea</Per>
        <Comments>Red</Comments>
    </External>
</Root>
