How to add a node to XML in C#?

Question

I have a huge XML file of 9 GB where i need to add a node:

XML File like:

<ABC>
  <DEF>
    <GHI>
      <AB>"ab"</AB>
       <CD>"cd"</CD>
       <EF>"ef"</EF> --NEED TO ADD
    </GHI>
  </DEF>
</ABC>
<PQR>
</PQR>

This is fixed that need too add in only ABC tag . XDocument will need so much resources any help is appreciated

@sani - No, the 9GB constraint means it is very much not a duplicate of that question. The answer there is not usable here. — Henk Holterman

Have a look here at how to stream in an XML document to avoid loading it in one go, then simply match on the element(s) you desire and add what you need in.

Interesting, I didn't know about XStreamingElement.

Use XmlReader/XmlWriter, XmlTextReader/XmlTextWriter (see here). These are fast, forward only reader/writers, that do not load the whole xml in one go so should cope with large files.
