It seems like you might not checking null before executing the above line

if (doc.DocumentNode.SelectNodes(@"//a[@href]" != null){

foreach (HtmlNode link in doc.DocumentNode.SelectNodes(@"//a[@href]")){

   //your code goes here
}

}

please share some more code too if above does not work.

Please let me know in case of any concerns.

Commented Issue: HtmlAgilityPack v1.4.3 parses tables wrong [32107]

Ksu — Wed, 22 Feb 2012 15:31:42 GMT

I have installed HtmlAgilityPack via NuGet and it installed version 1.4.3

This version has an error when handling tables!

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 3.2//EN">
<html>
<head>
<title>hap test table</title>
</head>
<body>
<table>
<tr>
<td>foo</td>
<td>bar</td>
</tr>
</table>
</body>
</html>

becomes

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 3.2//EN">
<html>
<head>
<title>hap test table</title>
</head>
<body>
<table>
<tr>
<td>foo
<td>bar
</td></td></tr></table>
</body>
</html>

If I go back to version 1.4.0 then it works like it should...
Comments: ** Comment from web user: Ksu **

I have to correct myself; version 1.4.0 from Codeplex works correct. Problem was I saved the loaded HTML files to my disk with version 1.4.3 so I didn't have to fetch them all the time through http. So my local copies all had the messed up td/tr closing tags. I fetched them all again with 1.4.0 and now it works.

Oh my god, and I thought I'm already mad.... I've been trying for hours to parse a table until I noticed the wrong closing td,tr tags in InnerHtml. This totally screwed up my XPath selectors and returns nodes that I don't want at all.

I have tried versions 1.4.3 from NuGet, 1.4.0 and 1.4.0 Beta 2 from Codeplex. They all have this issue.

I hope this will get fixed soon. At first I was so excited about how easy it is to parse HTML with HTMLAgilityPack until I tried to parse a table...

I'm using 1.4.0 (by the looks of it, in the Reference properties - gotten from Nuget 22/02/2012) - but still having a problem with a table not being read properly.

Viewing source in chrome or firefox shows the table to be properly formatted, but looking at InnerHtml of a further up node shows HtmlAgilityPack removing the ending tags from the TH,TR,TD tags ... and so it is having problems getting nodes out properly.

New Post: Code suggestion: Override ToString() in HtmlDocument

gruskada — Wed, 15 Feb 2012 21:20:00 GMT

I had to do some digging to figure out how to save the modified HTML document as a string, and I've seen a few other posts on the web asking the same question. It would be great if you could provide this as an override to ToString() to make it a bit more intuitive.

I had emailed Simon about this, but didn't get a response. If the powers that be think this suggestion is a bad idea for some reason, that's fine, just let me know. I'd like to contribute more to this project as well, but I want to make sure it's still active.

New Post: Can only load xml document from file system, not from web

wizardzz — Wed, 15 Feb 2012 18:57:14 GMT

Probably much too late to help you, but I ran into this problem as well. I will post what I found in the hopes of helping others than come across this.

In HtmlWeb.cs I added the bold part:

private bool IsHtmlContent(string contentType)

{

return contentType.ToLower().StartsWith("text/html") || contentType.ToLower().StartsWith("text/xml");

The place where this is crucial is in HtmlWeb.cs. Notice that the doc is never loaded if "html" is false, and html will be false because the ContentType of an online xml will be "text/xml". That is why I made the change above.

// try to work in-memory

if ((doc != null) && (html))

{
	if (respenc != null)
	{
		doc.Load(s, respenc);
	}
	else
	{
		doc.Load(s, true);
	}
}
