Issues with Parsing Nested XML Elements in C# - Unexpected Null Values
I'm optimizing some code but I'm sure I'm missing something obvious here, but I'm working through a tutorial and I just started working with I'm trying to configure After trying multiple solutions online, I still can't figure this out... I am trying to parse a nested XML structure using C# with System.Xml.Linq, but I am encountering unexpected null values when accessing certain elements. The XML looks like this: ```xml <store> <product> <name>Widget</name> <price>19.99</price> <details> <description>A great widget.</description> <dimensions> <width>5</width> <height>10</height> </dimensions> </details> </product> </store> ``` My parsing code is as follows: ```csharp XDocument xdoc = XDocument.Load("path/to/file.xml"); var product = xdoc.Element("store")?.Element("product"); var description = product?.Element("details")?.Element("description")?.Value; var width = product?.Element("details")?.Element("dimensions")?.Element("width")?.Value; ``` When I run this code, `description` returns the correct value "A great widget." but `width` returns `null`. I also tried using `FirstOrDefault()` with no success. I checked the XML structure multiple times, and it seems correct. I suspect that the issue lies in how I'm navigating through the XML tree, but I'm not sure what I'm missing. I've tried different variations of the element access syntax and using `SelectSingleNode` as an alternative, but I keep getting null values for the `width` element. I also verified that I have the correct namespaces, but since the XML provided doesn’t include any namespaces, that shouldn’t be an issue here. Does anyone have insights into why I'm encountering this issue? Could it be related to how nested elements are being accessed or perhaps something else in the XML structure that I might be overlooking? Any ideas what could be causing this? My development environment is CentOS. How would you solve this? I'd love to hear your thoughts on this. I've been using C# for about a year now. Any ideas what could be causing this? I'm working with C# in a Docker container on Linux. Thanks for any help you can provide! For context: I'm using C# on Windows 11. Is there a simpler solution I'm overlooking?
