Parse XML object from XLIFF file C#

Question

I am trying to Parse XML object with two namespaces inside the file.

<xliff srcLang="en" version="23.0"
  xmlns="asd:asd:asd:asd:xliff:document:23.0"
  xmlns:mda="asd:asd:asd:asd:xliff:document:23.0">   
    <file id="f"
      original="someUrl">
        <unit id="1" name="air">
          <mda:data>
            <mda:group category="attributes">
               <mda:meta type="id">Color</mda:meta>
               <mda:meta type="abbr">I_AI_LOW</mda:meta>
               <mda:meta type="type">Message</mda:meta>
             </mda:group>
           </mda:data>
           <segment>
             <source>Too many messages for 1 minute</source>
           </segment>
         </unit>   
    </file> 
</xliff>

I want to take the value from unit id="1" name="air" from property name, "mda:meta type="type" property type and source>Too many messages for 1 minute - property segment. I want to assign their value to other properties, so basically to extract their value.

My code now is:

 xliff = XDocument.Load(Path.GetFullPath(filePath));
 var ns = xliff.Root!.Name.Namespace;

 var elements = xliff.Descendants()
            .Elements(ns + "unit").ToList();

//this part not working
XElement tempElement = elements.Descendants(XName.Get("mda:metadata", 
ns.ToString())).FirstOrDefault()!;

I know that somehow I have to access the second namespace, but I don't know how to do it. Any help here will be appreciated.

Try using XNamespace and LINQ

XNamespace ns1 = "asd:asd:asd:asd:xliff:document:23.0";
XNamespace ns2 = "asd:asd:asd:asd:xliff:document:23.0";

var type_value = xliff.Descendants(ns1 + "unit")
    .Descendants(ns2 + "meta")
    .Where(x => (string)x.Attribute("type") == "type")
    .Select(y => y.Value)
    .FirstOrDefault()
    .ToString();

OR (to get all values to list)

var elements =  xliff.Descendants(ns1 + "unit")
    .Descendants(ns2 + "meta")
    .Where(x => (string)x.Attribute("type") == "type")
    .Select(y => y.Value.ToString())
    .ToList();

OR (to get source from segment)

var nameSegment = xliff.Descendants(ns1 + "unit")
    .Descendants(ns1 + "segment")
    .Select(x => x.Element(ns1 + "source").Value)
    .ToList();

There should be no values into linq, as I want to assign the value of each to another object. If you can provide example without ==1 and ==air – Sarah Aug 22 '22 at 13:30

@Sarah just remove where clause – Krishna Varma Aug 22 '22 at 13:33

Can you write the same for source and name ,which I think comes from unit? – Sarah Aug 22 '22 at 13:41
I need all values from the file for them into list. – Sarah Aug 22 '22 at 13:44
@Sarah, Possible.. have updated the post – Krishna Varma Aug 22 '22 at 13:48
var nameSegment = xliff.Descendants(x + "unit") .Where(x => (string)x.Attribute("segment") == "segment") .Select(x => x.Value.ToString()) .ToList(); not working with segment – Sarah Aug 22 '22 at 14:14

Try following :

            XDocument xliff = XDocument.Load(Path.GetFullPath(filePath));
            XNamespace ns = xliff.Root.GetDefaultNamespace();
            XNamespace nsMda = xliff.Root.GetNamespaceOfPrefix("mda");

            List<XElement> elements = xliff.Descendants(ns + "unit").ToList();

            //this part not working
            List<XElement> metaData = elements.Descendants(nsMda +  "metadata").ToList();

Yes, this works for the namespace, but if you can help a little bit more, how could I take only the described above properties ? – Sarah Aug 22 '22 at 13:16
