How to Access XML Attributes Using C#'s XmlDocument?

Accessing XML Attributes with XmlDocument

Reading XML attributes using C#'s XmlDocument can be achieved with a straightforward approach. Consider the following XML document:

<?xml version="1.0" encoding="utf-8" ?>
<MyConfiguration xmlns="http://tempuri.org/myOwnSchema.xsd" SuperNumber="1" SuperString="whipcream">
    <Other stuff />
</MyConfiguration>

To retrieve the attributes SuperNumber and SuperString, you can utilize the following code:

// Load the XML document
XmlDocument doc = new XmlDocument();
doc.Load("myConfig.xml");

// Get the specified element by its tag name
XmlNodeList elemList = doc.GetElementsByTagName("MyConfiguration");

// Iterate through the matching elements
for (int i = 0; i < elemList.Count; i++)
{
    // Access the attribute value
    string attrVal = elemList[i].Attributes["SuperString"].Value;
}

This code snippet uses the GetElementsByTagName method to find the MyConfiguration element. It then iterates through the resulting list and accesses the "SuperString" attribute using the Attributes property. The Value property of the attribute object provides the actual attribute value.

By utilizing this approach, you can easily read and process XML attributes using the XmlDocument class in C#.
