Add HtmlAgility Pack And Abot Web Crawler to Project

Question

I Use "Abot" Version 1.2.3.1 but when I add "Html Agility" version 1.4.6.0 to project I get this error :

Error 38 Assembly 'Abot, Version=1.2.3.1, Culture=neutral, PublicKeyToken=null' uses 'HtmlAgilityPack, Version=1.4.7.0, Culture=neutral, PublicKeyToken=bd319b19eaf3b43a' which has a higher version than referenced assembly 'HtmlAgilityPack, Version=1.4.6.0, Culture=neutral, PublicKeyToken=bd319b19eaf3b43a'

I know this is old but I just ran into this issue. That is, Abot did not work when I had added the latest version of HAP. But the workaround is simple, just use the CSQueryHyperlinkParser to parse links. Like so:

var crawler = new Abot.Crawler.PoliteWebCrawler(config, null, null, null, null, new Abot.Core.CSQueryHyperlinkParser(), null, null, null);

This solved my issue.

Abot uses a patched version of html agility pack since it would crash the process on certain types of html pages. See the issue documented here...

https://code.google.com/p/abot/issues/detail?id=77&can=1&q=htmlagilitypack

There is an issue on github to investigate if this was still a problem with the nuget version of html agility pack (which i'm pretty sure there is). So until the nuget version will not crash the host process Abot will like keep it's patched version of html agility pack.
