c# html html-agility-pack
Question
I'm trying to get all HTML elements with a certain string in their attribute values into the code below.
<meta name="DCSext.oo_market" content="en-us">
<a href="http://office.microsoft.com/en-us/support/" title="Find help for Word">
<a href="http://windows.microsoft.com/en-us/windows-live/microsoft-account-help#microsoft-account=tab1" title="Microsoft Account">
I want all the html tags with the attribute "en-us," hence my output must include all of the aforementioned html elements. Could someone kindly tell me how to use HTML Agility Pack to acquire it?
Accepted Answer
You may use the XPath below.//*[@*[contains(., 'en-us')]]
This chooses any components whose attributes include strings.en-us
:
HtmlDocument doc = new HtmlDocument();
doc.Load(path_to_html_file);
var nodes = doc.DocumentNode.SelectNodes("//*[@*[contains(., 'en-us')]]");
or using LINQ:
var nodes = doc.DocumentNode.Descendants()
.Where(n => n.Attributes.Any(a => a.Value.Contains("en-us")));
