Trouble Accessing Deeply Nested XML Elements with XmlDocument in C#
I'm trying to parse an XML document using `XmlDocument` in C#, but I'm having trouble accessing elements that are deeply nested. My XML structure looks like this: ```xml <root> <level1> <level2> <level3> <value>123</value> </level3> </level2> </level1> </root> ``` I'm using the following code to access the `value` element: ```csharp XmlDocument xmlDoc = new XmlDocument(); xmlDoc.Load("path_to_xml_file.xml"); XmlNode valueNode = xmlDoc.SelectSingleNode("/root/level1/level2/level3/value"); if (valueNode != null) { Console.WriteLine(valueNode.InnerText); } else { Console.WriteLine("Value node not found."); } ``` Despite the XML being structured as shown, I'm getting `"Value node not found."` as output. I've verified that the file path is correct, and the XML is well-formed. Could there be something wrong with the XPath query I'm using? I've also tried using `GetElementsByTagName` method, but it seems inefficient for such deeply nested structures. Any insights or recommendations on accessing deeply nested XML nodes using `XmlDocument` would be greatly appreciated. I'm currently using .NET Framework 4.8.1. For context: I'm using C# on Windows. What am I doing wrong? Has anyone dealt with something similar? What would be the recommended way to handle this?
