HtmlElement.GetAttribute Method (String)


Retrieves the value of the named attribute on the element.

Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public string GetAttribute(
	string attributeName


Type: System.String

The name of the attribute. This argument is case-insensitive.

Return Value

Type: System.String

The value of this attribute on the element, as a String value. If the specified attribute does not exist on this element, returns an empty string.

An attribute in HTML is any valid name/value pair for that element. HtmlElement exposes only those attributes that are common to all elements, leaving out those that only apply to certain types of elements; SRC is a predefined attribute for the IMG tag, for example, but not for the DIV tag. Use GetAttribute and SetAttribute to manipulate attributes not exposed on the managed Document Object Model (DOM).

GetAttribute and SetAttribute are case-insensitive.

The following code example retrieves all of the META tags within an HTML document, using GetAttribute to find the META tag with the name Description. The example requires that your application has a WebBrowser control named WebBrowser1.

private void DisplayMetaDescription()
    if (webBrowser1.Document != null)
        HtmlElementCollection elems = webBrowser1.Document.GetElementsByTagName("META");
        foreach (HtmlElement elem in elems)
            String nameStr = elem.GetAttribute("name");
            if (nameStr != null && nameStr.Length != 0)
                String contentStr = elem.GetAttribute("content");
                MessageBox.Show("Document: " + webBrowser1.Url.ToString() + "\nDescription: " + contentStr);
