Printing XML Node Names and Values without LINQ in C

When working with XML files in C, you might want to read and display the node names and values without using LINQ. Although LINQ to XML is a powerful tool, it's useful to know alternative methods, particularly when LINQ is not an option. This post will cover how to read an XML file in C and print the node names and values using the System.Xml namespace.

How to Read an XML File in C

To start, you need to read the XML file. You can do this using the XmlDocument class from the System.Xml namespace. Here’s a basic example:

In this example, you first create an instance of XmlDocument and load the XML file using doc.Load(). The GetElementsByTagName("*") method retrieves all the elements in the XML document.

Printing Node Names and Values

Once you have the list of all elements, you can iterate over them using a foreach loop. For each node, you print the node name and the text value contained within it. The key methods used here are:

node.Name which gives the name of the node.

node.InnerText which gives the text content of the node.

Example Output

Suppose your XML file looks like this:

Conclusion

Reading XML files and printing node names and values in C without LINQ is straightforward using the XmlDocument class and the XmlNodeList collections. By understanding how to use these classes, you can effectively parse and display the structure and content of XML documents, an essential skill for many C developers.
