How to Get XML InnerText with Namespace Using XDocument and XmlDocument in C#

Working with XML files in C# can sometimes be challenging, especially when dealing with namespaces. This can particularly be frustrating when you want to extract information from XML, such as user names, and the XML structure includes namespaces. In this guide, we’ll walk through a solution for extracting this information using XDocument and LINQ.

The Problem

Imagine you have an XML file structured like this:

You want to extract the first and last names from the <Name> elements while considering the namespace that the XML defines. Let's explore how to do this using C# .

The Solution

We will utilize the XDocument class from the System.Xml.Linq namespace, which allows us to load, query, and process XML data effectively. Here’s a step-by-step breakdown of the solution.

Step 1: Setup Your C# Environment

You need to set up a console application in C# . Ensure you have access to the necessary namespaces:

Step 2: Load the XML Document

Load your XML file into an XDocument instance. Make sure to adjust the file path to point to your XML file correctly.

Step 3: Handle Namespaces

To work with elements that are under a namespace, first fetch the default namespace:

Here, ns holds the namespace defined within your XML, which we’ll use to access the <Name>, <FirstName>, and <LastName> elements.

Step 4: Query the XML for Names

Now, you can query the XML to get all the user names. The LINQ query will select every <Name> element, extracting both the first and last names as shown below:

Step 5: Display the Results

Finally, you can iterate over the results to display the names:

Conclusion

By following the steps outlined above, you should now be able to extract data from XML files that use namespaces in C# . Utilizing XDocument along with LINQ makes the process efficient and straightforward.
