Question

I have xml like below. I want to delete nth product node from that xml.

I had tried this but not working.

document.Descendants("products").Descendants("product").Take(1)

XML

<products>
    <product>
        <territory>A</territory>
    </product>
    <product>
        <territory>B</territory>
    </product>
    <product>
        <territory>C</territory>
    </product>
    <product>
        <territory>D</territory>
    </product>
    <product>
        <territory>E</territory>
    </product>
</products>

How to delete 3rd product node from this xml?

Answer 1

You can't access child nodes by using an index. One way would be:

document.Descendants("products").Descendants("product").Skip(2).Take(1);

Answer 2

I suggest using Linq to Xml . You could use ElementAt and find an element at a given position, one could call Remove on a find element to remove the element.

    int position = 3;  // Specify position.
    XElement element = XElement.Parse(input);

    element                                      
        .Elements("product")
        .ElementAt(3)
        .Remove();

Ouput

 <products>
  <product>
    <territory>A</territory>
  </product>
  <product>
    <territory>B</territory>
  </product>
  <product>
    <territory>C</territory>
  </product>
  <product>
    <territory>E</territory>
  </product>
</products>
