Parsing XML with Mixed Namespace Declarations in C# - Unexpected Null Reference Exceptions
Can someone help me understand I'm trying to figure out I'm trying to debug I'm sure I'm missing something obvious here, but Quick question that's been bugging me - I'm currently working on parsing an XML document that has mixed namespace declarations, and I'm working with a `NullReferenceException` when trying to access elements within those namespaces... The XML structure looks something like this: ```xml <root xmlns:ns1="http://example.com/ns1" xmlns:ns2="http://example.com/ns2"> <ns1:item> <ns1:name>Item 1</ns1:name> </ns1:item> <ns2:item> <ns2:name>Item 2</ns2:name> </ns2:item> </root> ``` Iām using `System.Xml.Linq` to parse the XML like this: ```csharp XDocument doc = XDocument.Load("path/to/xmlfile.xml"); var ns1 = "http://example.com/ns1"; var ns2 = "http://example.com/ns2"; var items1 = doc.Descendants(XName.Get("item", ns1)); foreach (var item in items1) { var name = item.Element(XName.Get("name", ns1))?.Value; Console.WriteLine(name); } var items2 = doc.Descendants(XName.Get("item", ns2)); foreach (var item in items2) { var name = item.Element(XName.Get("name", ns2))?.Value; Console.WriteLine(name); } ``` When I run this code, I get a `System.NullReferenceException` at `var name = item.Element(XName.Get("name", ns2))?.Value;` for the second namespace items, even though I can see the items in the XML. I've verified that the namespaces are being correctly assigned. I tried checking if `item` is null before accessing its elements, but it still throws the exception. I also used `item.Descendants()` instead of `item.Element()`, but that didn't resolve the scenario. Can anyone guide to figure out what's going wrong here? Am I missing something in how namespaces work in LINQ to XML? I'd really appreciate any guidance on this. I'm working on a API that needs to handle this. I'd really appreciate any guidance on this. Cheers for any assistance! I'm coming from a different tech stack and learning C#. This issue appeared after updating to C# 3.10.
