AngleSharp.XPath

AngleSharp.XPath extends AngleSharp with the ability to select nodes via XPath queries instead of CSS selector syntax. This is more powerful and potentially more common for .NET developers working with XML on a daily basis.

Basic Use

With this library using XPath queries is as simple as writing

var contentNode = document.Body.SelectSingleNode("//div[@id='content']");

Besides SelectSingleNode we can also use SelectNodes. Both are extension methods defined in the AngleSharp.XPath namespace.

If wanted we can also use XPath directly in CSS selectors such as in QuerySelector or QuerySelectorAll calls. For this we only need to apply the following configuration:

var config = Configuration.Default.WithXPath();

Now we can write queries such as

var secondLi = document.QuerySelector("*[xpath>'//li[2]']");

It is important that the original selector has all elements (*) as the intersection of the ordinary CSS selector and the XPath attribute is considered. The XPath attribute consists of a head (xpath>) and a value - provided as a string, e.g., //li[2].

Features

• Uses XPathNavigator from System.Xml.XPath
• Includes XPath capabilities to CSS query selectors if wanted
