How to Efficiently Retrieve XML Attribute Values Using XmlDocument in C#?

Getting XML Attribute Values with XmlDocument

When dealing with XML data in C#, the XmlDocument class provides a convenient way to read and navigate through the document's structure. However, obtaining attribute values can sometimes be a challenge. Let's explore how to effortlessly retrieve XML attribute values using XmlDocument.

In the provided XML snippet, the attributes SuperNumber and SuperString are assigned to the MyConfiguration node. To access these attributes using XmlDocument, you can utilize the GetElementsByTagName() method:

// Assuming 'doc' is an XmlDocument object instantiated earlier

// Retrieve MyConfiguration nodes
XmlNodeList elemList = doc.GetElementsByTagName("MyConfiguration");

Once you have the nodes, you can iterate over them and retrieve the attribute values:

for (int i = 0; i < elemList.Count; i++)
{
    // Access the SuperString attribute value
    string superStringAttrVal = elemList[i].Attributes["SuperString"].Value;

    // Access the SuperNumber attribute value
    int superNumberAttrVal = int.Parse(elemList[i].Attributes["SuperNumber"].Value);
}

By using this approach, you can easily extract attribute values from your XML document, allowing you to leverage the data effectively in your application.
