XPath Queries Not Returning Expected Results in C# with XmlDocument - Namespaces guide
I'm attempting to set up After trying multiple solutions online, I still can't figure this out. I've tried everything I can think of but I'm trying to use XPath queries to extract data from an XML document using C#'s `XmlDocument`, but I'm not getting the expected results due to namespaces in the XML. My XML looks like this: ```xml <root xmlns:ns="http://example.com/ns"> <ns:item> <ns:name>Item1</ns:name> </ns:item> <ns:item> <ns:name>Item2</ns:name> </ns:item> </root> ``` In my C# code, I load the XML and set up the XPath like this: ```csharp XmlDocument doc = new XmlDocument(); doc.Load("path/to/your/file.xml"); XmlNamespaceManager nsmgr = new XmlNamespaceManager(doc.NameTable); nsmgr.AddNamespace("ns", "http://example.com/ns"); XmlNodeList items = doc.SelectNodes("//ns:item", nsmgr); ``` However, `items` is returning an empty list, even though I can see that there are `ns:item` nodes in the XML. I've tried different XPath expressions, but none seem to work. I also confirmed that the namespace is correctly defined in the XML. What am I missing here? Is there a specific way to handle namespaces in XPath queries with `XmlDocument`? I've also looked into using `XDocument`, but I would like to stick with `XmlDocument` for this task. Any insights would be appreciated! For context: I'm using C# on Ubuntu 22.04. Any ideas how to fix this? For reference, this is a production CLI tool. I'd love to hear your thoughts on this. Am I approaching this the right way? Any examples would be super helpful.
