Question

I have a XML file containing some elements like

 <root>
    <gp>
      <i>1</i>
      <i>3</i>
      <i>5</i>
    </gp>
    <gp>
      <i>5</i>
      <i>6</i>
    </gp>
     . 
     . 
 </root>

Now i want to write a query by which i will get all gp elements which contains the <i> element with value 5?`

Answer 1

var results = from gp in doc.Descendants("gp")
              where gp.Elements("i").Any(i => (int)i == 5)
              select gp

And in method-based syntax:

var results = doc.Descendants("gp").Where(gp => gp.Elements("i").Any(i => (int)i == 5));
