Question

<?xml version="1.0" encoding="utf-8" ?>
<MYROOT>
  <Group name="G1">
      <Skill name="G1Skill1">
              <SubSkill>G1skill1sub1</SubSkill>
              <SubSkill>G1skill1sub2</SubSkill>
      </Skill >
    <Skill name="G1Skill2">
              <SubSkill>G1skill2sub1</SubSkill>
              <SubSkill>G1skill2sub2</SubSkill>
      </Skill >
  </Group>
  <Group name="G2">
    <Skill name="G2Skill1">
              <SubSkill>G2skill1sub1</SubSkill>
              <SubSkill>G2skill1sub2</SubSkill>
    </Skill >
    <Skill name="G2Skill2">
              <SubSkill>G2skill2sub1</SubSkill>
              <SubSkill>G2skill2sub2</SubSkill>
    </Skill >
 </Group>
</MYROOT>

For e.g .
Inputs are "G1" & "G1skill1sub1"

Expected output = G1Skill1 (Using single LINQ to XML)

I tried this code :

  var xmlDoc = XDocument.Load(Server.MapPath("XMLFile1.xml"));
        var skills =
        from skill in xmlDoc.Descendants("Group")
        where skill.Attribute("name").Value.Equals("G1") // && skill.Element("SubSkill").Value.Equals("Group")
        select new
            {
                Myskill = skill.Element("Skill").Value,
                mytext= skill.Attribute("name").Value,
            };

But don’t get proper output .

Answer 1

I would use:

var skills = from group in doc.Descendants("Group")
             where (string) group.Attribute("name") == "G1"
             from subskill in group.Descendants("SubSkill")
             where (string) subskill == "G1skill1sub1"
             select (string) subskill.Parent.Attribute("name");

That’s going by your inputs and expected output:

• Find all matching groups
• Find all matching subskills within those groups
• For each matching subskill, find the name of the parent (skill)
