I want to create a robot to find news in my defined website, so my robot fetch the html code from the website and I should find the news part of the html code. For example one of the pattern that I should find is like this :

<li><a href="/news?p_p_id=56_INSTANCE_tVzMoLp4zfGh&_56_INSTANCE_tVzMoLp4zfGh_mode=news&_56_INSTANCE_tVzMoLp4zfGh_newsId=3206056&p_p_state=maximized">بازدید رئیس هیئت عامل صندوق نوآوری و شکوفایی از خبرگزاری مهر</a></li>

I want to know how can I find these pattern in the html code in C#. I googled it and i found something like regular expression. But in regular expression I can't define patterns. Can I define some pattern like this? With this complexity?

Do not parse html/xml with a regex. Use a library. Regexes cannot parse hml/xml... – Willem Van Onsem Jan 12 '16 at 13:13
@WillemVanOnsem which kind of library ? – Ehsan Akbar Jan 12 '16 at 13:15

HtmlAgilityPack is the standard. – RB. Jan 12 '16 at 13:15

[obligatory reference on html vs. regex](http://stackoverflow.com/a/1732454/1336590) – Corak Jan 12 '16 at 13:18
It could be done in multiple ways. first find the tags. then you parse them individualy. and by gaining experience you will define allot cases for each urls. – Shmalex Jan 12 '16 at 13:19
