Select elements with attribute data-url using HTMLAgilityPack

Select elements with attribute data-url using HTMLAgilityPack

To select elements with an attribute data-url using HTMLAgilityPack in C#, you can use the SelectNodes method of the HtmlDocument class and specify an XPath expression that matches the desired elements.

Here's an example:

using HtmlAgilityPack; // Load the HTML document from a string or file HtmlDocument doc = new HtmlDocument(); doc.Load("path/to/file.html"); // Select all elements with a data-url attribute HtmlNodeCollection nodes = doc.DocumentNode.SelectNodes("//*[@data-url]"); // Iterate over the selected nodes and get the value of the data-url attribute foreach (HtmlNode node in nodes) { string dataUrl = node.Attributes["data-url"].Value; // Do something with the dataUrl value }

In this example, we create an instance of the HtmlDocument class and load an HTML document from a file using the Load method. We then use the SelectNodes method of the DocumentNode property to select all nodes that have a data-url attribute, using the XPath expression "//*[@data-url]".

We then iterate over the selected nodes using a foreach loop and get the value of the data-url attribute using the Value property of the Attributes collection.

Note that you can modify the XPath expression to match different patterns of elements with data-url attributes. For example, you could use "//a[@data-url]" to select only a elements with a data-url attribute, or "//*[@data-url='value']" to select only elements with a specific value for the data-url attribute.
