How to deserialize this kind of XML document : 

<?xml version="1.0" encoding="utf-8"?>
<ModelInformation Version="0.9">
<Model>
<Block BlockType="SubSysteme" Name="subSysteme1">
   <p Nom="tag">xx</P>
   <p Nom="coordonee">xx</P>
   <System>
      <p Name="source">xx</P>
      <Block BlockType="Entree" Name="Entree_1">
         <p Name="coordonne"</P>
      </Block> 
      <Block BlockType="Entree" Name="Entree_2">
         <p Name="coordonne">xx</P>
      </Block>
      <Block BlockType="Entree" Name="Sortie_3">
         <p Name="coordonne">xx</P>
      </Block>
      <Block BlockType="SubSysteme" Name="SubSysteme1.01">
         <p Name="tag">xx</P>
         <p Name="coordonne">xx</P>
         <System>
            <p Name="source">xx</P>
            <Block BlockType="Entree" Name="XXX">
               <p Name="coordonne"</P> 
            </Block>
            <Block BlockType="Sortie" Name="XXX">
               <p Name="coordonne">xx</P>
            </Block>
         </System>
      </Block>
   </System>
</Block
</Model>
</ModelInformation>

There can be have several systems,subsystems,blocks...

I need to retrieve their attributes names.

First I tried this : 

public class Block
{
    public Block() { }

    /*[XmlAttribute("BlockType")]
    public String BlockType { get; set; }*/

    [XmlAttribute("Name")]
    public String Name { get; set; }

    [XmlArrayItem("Block")]
    public List<BlockType> BlockTypes = new List<BlockType>();
}

and the main : 

Block block = null;
            using (var stream = new StreamReader(@"C:\Users\U503124\Desktop\BstSP_v41_01460_14_01420_v41_0\simulink\blockdiagram.xml"))
            {
                var serialiser = new XmlSerializer(typeof(Block));
                subsystem = (Block)serialiser.Deserialize(stream);
                Console.WriteLine(block.Name);

            }

block.Name is null, I don't know why.

There are the same tag HTLM inside tag HTLM. How to process?

  • In some cases I see `

    xx

    ` and in others I see `

    xx

    ` Is it really true that sometimes the attribute is named `Nom` and sometimes it is `Name`, or is this a typo in your question?     – dbc Feb 19 '18 at 18:42

Your XML is invalid so first thing to do is fix that.

<ModelInformation Version="0.9">
   <Model>
      <Block BlockType="SubSysteme" Name="subSysteme1">
         <P Nom="tag">xx</P>
         <P Nom="coordonee">xx</P>
         <System>
            <P Name="source">xx</P>
            <Block BlockType="Entree" Name="Entree_1">
               <P Name="coordonne"></P>
            </Block> 
            <Block BlockType="Entree" Name="Entree_2">
               <P Name="coordonne">xx</P>
            </Block>
            <Block BlockType="Entree" Name="Sortie_3">
               <P Name="coordonne">xx</P>
            </Block>
            <Block BlockType="SubSysteme" Name="SubSysteme1.01">
               <P Name="tag">xx</P>
               <P Name="coordonne">xx</P>
               <System>
                  <P Name="source">xx</P>
                  <Block BlockType="Entree" Name="XXX">
                     <P Name="coordonne"></P> 
                  </Block>
                  <Block BlockType="Sortie" Name="XXX">
                     <P Name="coordonne">xx</P>
                  </Block>
               </System>
            </Block>
         </System>
      </Block>
   </Model>
</ModelInformation>

... then you can Paste Special -> Paste XML as class

You get something like this as your class representation. This can be tidied up a lot.

Then use your serialise/deserialise.
