how to get the values of an attribute of an element using XMlElement

asp.net, c#, c#-4.0, xml

Solution

Since you're using C# 4.0 you could use linq-to-xml like this:

XDocument xdoc = XDocument.Load(@"C:\Tmp\your-xml-file.xml");
foreach (var item in xdoc.Descendants("a"))
{
   Console.WriteLine(item.Attribute("id").Value);
}

Should give you the element `a` regardless of where it is in the hierarchy.

From your comment, for code that only uses the XmlDocument and XmlElement classes the equivalent code would be:

XmlDocument dd = new XmlDocument();
dd.Load(@"C:\Tmp\test.xml");
XmlElement theElem = ((XmlElement)dd.GetElementsByTagName("data")[0]);
//         ^^ this is your target element 
foreach (XmlElement item in theElem.GetElementsByTagName("a"))//get the <a>
{
    Console.WriteLine(item.Attributes["id"].Value);//get their attributes
}

Problem

I am working on `XmlElement` in c#. I have an `XmlElement`. The source of the `XmlElement` will look like the sample below. Sample: ``` <data> <p>hello all <strong> <a id="ID1" href="#" name="ZZZ">Name</a> </strong> </p> <a id="ID2" href="#" name="ABC">Address</a> </data> ``` I have to loop through the above XML to Search for element name `a`. I also want to extract the ID of that element into a variable. Basically I want to get the ID attribute of the element `<a>`. It may occur as a child element or as a separate parent. Can any one help how it can be done.
