Select elements with attribute data-url using HTMLAgilityPack

Question

I'm writing a little Download-Roboter, that is searching for links in lower layers for it self. What i need to find are all links in an html-Page (the links to .jpg files as well as the links to .pgn, .pdf, .html,.... - files) I´m using the html-agilitypack to find all a-href links. Sample code: ``` foreach (HtmlNode link in htmlDocument.DocumentNode.SelectNodes("//a[@href]")) { HtmlAttribute attribute = link.Attributes["href"]; links.Add(attribute.Value); } ``` But i want to find the data-urls as well. What XPath-syntax do i have to use to find data-urls. An example data-url in an htmlcode: ```

``` I need the "2012\edmonton\partien.pgn" out of this example. How can i realize this with XPath syntax? Best greetings, if i made some bad mistakes, tell me. This is my first question ever.

Accepted Answer

The following should do what you want:

```
foreach (HtmlNode divNode in htmlDocument.DocumentNode.SelectNodes("//div[@data-url]"))
{
    HtmlAttribute attribute = divNode.Attributes["data-url"];
    links.Add(attribute.Value);
}
```

Effectively, the statement `//div[@data-url]` should select all nodes with a data-url attribute. We then pull out this attribute.

If there are nodes other than divs with this attribute, then `//*[@data-url]` should do the trick.
