I have the following TagOpen
[TagOpen "a"
[("href","/launchWebForward.do?resourceId=4&policy=0&returnTo=%2FshowWebForwards.do")]]
I would like to get the attribute resourceId=4 from that. My
understanding is that fromAttrib is the right thing to use. But
I'm having difficulty understanding the type signature
fromAttrib :: (Show str, Eq str, StringLike str) => str -> Tag str -> str
I'm sure if I did, the way to use it would be clear. Could someone
help me make sense of this?
