Question

I have xml Node with following format. This node must be converted to userdefined type that is each node must convert to object of say MyClass

class MyClass
{
  public string tag1Id {get;set;}
  public int tag3Val {get;set;}
  public string tag3Id {get;set;}
  public int tag5Val {get;set;}
  public string tag5Id {get;set;}
  public DataTime tag7Val {get;set;}

}

  <tag1 id="id1">
     <tag2>
       <tag3 id="id3">10</tag3>
       <tag4>
        <tag5 id="id5">20</tag5>
       </tag4>
     </tag2>
     <tag6>
      <tag7>2010-12-31</tag7>
     </tag6>
    </tag1>

I am new to linq, Can it be done using linq. Requirement is xmlseralization should not be used 🙁
Is there any other approach by which this scenario can be handled easily?

Answer 1

No it cannot be done.

There must be a conversion done somewhere due to the business logic plumbing to go to the specific properties from the exacting node ids/locations.

What can be done is to code a constructor which takes in the node and populates the properties accordingly. Linq can then be used to enumerate over the nodes and create a new projection of the class elements via select such as:

     string data = @"
<tags>
  <tag id=""id1""> 
     <tag2> 
       <tag3 id=""id3"">10</tag3> 
       <tag4> 
        <tag5 id=""id5"">20</tag5> 
       </tag4> 
     </tag2> 
     <tag6> 
      <tag7>2010-12-31</tag7> 
     </tag6> 
    </tag> 
</tags>
    ";
var xml = XDocument.Parse(data);

    var classes = xml.Descendants( "tag1" )
                     .Select( nd => new MyClass( nd ) );
