Regular expression

[Jeffrey Massung]

regex should be 

	if matchText(tInputString, "src='([^']*)'", tSourceMatched) is true then
		put tSourceMatched
	end if

Of course, many of the other suggestions posed by others w/o using regex are fine, too. Just letting you know how to do this with regex as well.
