Need help in making xml link node modification?

Question

I have some xml files which contains nodes like disp-formula   id = "deqn1" > ...disp-formula >    disp-formula   id = "deqn2-5" > ...disp-formula >    disp-formula   id = "deqn6-9" > ...disp-formula >    disp-formula   id = "deqn10" > ...disp-formula >    along with other nodes in the file. Also the file has link nodes related to the above nodes like xref   ref-type = "disp-formula"   rid = "deqn1" > ...xref >    xref   ref-type = "disp-formula"   rid = "deqn3" > ...xref >    xref   ref-type = "disp-formula"   rid = "deqn8" > ...xref >    I'm trying to modify those link nodes ...xref> to ...xref>, ...xref> to ...xref> and so on, as there are no such thing as id="deqn3", id="deqn8" in the file and attribute values like deqn3, deqn8 fall in the range of the attributes and   that is why there are replaced by their respective id's.   How do I do this using LINQ to xml?   I dont even know where to start and how do I structure the procedures required?   Please help!!

Hi, Satyaprakash Thanks for that link, but my requirements are more complicated. I need to find a range of values starting from deqnX to deqnY (increment X by 1 until it reaches Y) and replace all found with deqnX-Y and there could be multiple items in the file also.
