A C# regex question: retrieve Google search results
I want to store Google search results (both title and link) into database. HTML code of search results is like:
<br/>
THETITLE
And each page has 10 results. Can anyone show me how to retrieve THEURL
and THETITLE
?
Thank you so m开发者_开发问答uch!
You should to give Html Agility Pack a try. An HTML parser is correct way to read HTML content, not regular expressions.
BUT, If you wanna try for your own risk:
<h3 class=r><a .*? href="(?<url>[^"]*)".*?>(?<title>.*?)</a></h3>
You'll have problems with:
- Line breaks
- Unmatched tags
- Minor HTML changes
So, good luck!
For starters, I would not recommend using regex for this, use the 'Html Agility Pack' to do the parsing of the HTML document.
Hope this helps, Best regards, Tom.
Consider using the Google AJAX Search API instead. It will be easier on both you and Google's servers. There are some instructions for using it outside JavaScript environments. They don't give a C# example, but it shouldn't be difficult to adapt to your needs using one of the JSON APIs for C#.
If you do stick with HTML, I also recommend HTML Agility Pack.
You should also think about caching so you minimize both stale data and unnecessary requests.
