How to copy a node xml and appended to the specified node using linq to XML

Question

I have an xml,like this :

<advReqData>
  <sessionid></sessionid>
  <akc190></akc190>
  <meds>
    <med>
      <idx></idx>
      <alc400></alc400>
    </med>
  </meds>
</advReqData>

I would like to using linq to xml make XML into the following structure:

<advReqData>
  <sessionid></sessionid>
  <akc190></akc190>
  <meds>
    <med>
      <idx></idx>
      <alc400></alc400>
    </med>
    <med>
      <idx></idx>
      <alc400></alc400>
    </med>
  </meds>
</advReqData>

That is, in the meds node under the addition of a new med node, the new med node and the original document med node structure is the same.

How do I do it?

Answer 1

This will get the first element in "meds" and then add it to the end

var fn = xelement.Element("meds").FirstNode;
xelement.Element("meds").Add(fn);
