XPath Query Returns Empty Node Set in C# When Searching for Specific XML Attributes
Could someone explain I'm upgrading from an older version and I'm working on parsing an XML file in C# using `System.Xml` and I run into an scenario where my XPath query returns an empty node set when trying to filter nodes based on specific attributes. Here’s a snippet of the XML I'm dealing with: ```xml <store> <item id="1" category="electronics"> <name>Laptop</name> <price>999.99</price> </item> <item id="2" category="books"> <name>Programming 101</name> <price>29.99</price> </item> </store> ``` I’m using the following code to retrieve items in the `electronics` category: ```csharp XmlDocument xmlDoc = new XmlDocument(); xmlDoc.Load("store.xml"); XmlNodeList electronicsItems = xmlDoc.SelectNodes("/store/item[@category='electronics']"); ``` However, the `electronicsItems` node list comes back empty, and I need to seem to find the scenario. I have checked that the XML is loaded correctly, and I can print the outer XML of `xmlDoc`, which shows the structure is intact. I’ve ensured the attribute name is exactly as in the XML, including the correct casing. When I try the following XPath directly in an XML editor, it returns the expected item: ``` /store/item[@category='electronics'] ``` I also tried using `XmlDocument.SelectSingleNode()` to see if it was a list scenario, but that returned null as well. I even looked into potential namespace issues, which shouldn't apply here since there are no namespaces in the document. Is there something I'm missing in my XPath syntax or a specific aspect of `XmlDocument` that could cause this? Any insights would be appreciated! Any help would be greatly appreciated!
