Does anyone know how to make something that would work for both
the following ways a URL is found in HTML source code?

Code:
<a href="http://freezingfire.vdsworld.com">test</a>
<a href=http://freezingfire.vdsworld.com>test</a>

Why not search for the string http://, start parsing from that POSition and get the substring up till it finds a " or >. You may also want to use the TRIM function afterward in case there were any extra spaces in between which will be removed out.

Good idea. Very Happy

I didn't think of that. I'm making a site crawler, I'll probably share it when
it's done. Smile

If you make a site crawler, please note that there are a lot of links which only display "pagename.html" for example. I think it's better in this case to search for "<a href=", and to check if that will start with http:// or not... Smile
