XML, XPath in .net

@Amit: Thanx for ur reply dear, I have tried everything. "/LINE" , "//RESPONSE/LINE" and so on. I have done the job but i used DOM, where i had to loop through every element. I have used Xpath in the past and used its advanced features too. worked fine for every xml doc. i dont know what is wrong with this particular document or its schema. Can anyone of u pls try using xpath urself on the said document.???
