Extract html img tag in a string in c#

Question

I have a html code as a string. I need to remove the img tag in that which has a particular src attribute.

e.g. <img style="WIDTH:439px;" src="http://test/a.png">

Say I need to find img tags which has "test" src attribute and remove the entire img tag from the string.

Thanks in advance
