从 XLIFF 文件 C# 中解析 XML object

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.

Answer 1

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();

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();
