how to extract certain rows of a table from html using regex
I need to extract certain records from an html page. And those recrods are in the form of table and I need only those rows which have a "Review" button in them. The link for the web page is http://campbellcollaboration.org/lib/index.php?noframe&go=browse_small&sort=title&view=all
or I have pasted html of three rows from where I need to filter the records
Get only those rows which have <span style="padding: 3px;">Review</span>
thanks
