Custom Root element about yaxlib

[sinairv]

The YAXSerializer.Deserialize method has 2 overrides that receive a string or an XElement which you can use. You can pass that section of the XML as a string to the method, as long as it remains a well formed XML. Or alternatively, you can open the whole document as an XDocument, find the desired element using LINQ to XML, and pass the corresponding XElement object to the method.

Thats a good idea!
I'm new to XML to Linq and have no idea how to do this.
Could you please give an example, how this would look like in code if I'd be looking for a Element called "product-parameters"?

To elaborate, I've already tried the following:

XDocument x = XDocument.Parse(response.Content);
XNamespace xns = x.Root.Name.Namespace;
XElement xe = x.Element(xns +  "product-parameters");

But xe is still null for some reason, even though I'm sure a element product-parameters exists in the XML.

Figured out this part, but now I've different problems...
If I can't figure it out I'll open another Issue, thanks for the support here!
