tag in an external html using html agility pack? c# html html-agility-pack xpath
I am trying to get some text from an external site. The text I am trying to get is nested in a paragraph tag. The div has has a class value
html code snippet:
<div class="discription"><p>this is the text I want to grab</p></div>
current c# code:
public String getDiscription(string url)
{
var web = new HtmlWeb();
var doc = web.Load(url);
var nodes = doc.DocumentNode.SelectNodes("//div[@class='discription']");
if (nodes != null)
{
foreach (var node in nodes)
{
string Description = node.InnerHtml;
return Description;
}
} else
{
string error = "could not find text";
return error;
}
}
what I dont understand is the syntax of the xpath //div[@class='discription']
I know it is wrong what should the xpath be?
use //div[@class='discription']/p
.
Breakdown:
//div - All div elements
[@class='discription'] - With a class attribute whose value is discription
/p - Select the child p elements
