HREF exploit

There's an exploit in the message system of some PHP code I'm developing that's really annoying. <a href=" >link</a> Note: there's only one quotation mark in the tag. It causes the whole page not to display in Netscape. I've included the sum of my work. I've tried to pluck out the stuff that's in the middle of the tag, count the number of quotes, and just delete all quotes if it counts an odd number (since the tag will work the same) and leave them in if even because they'll all cancel each other out. What I've got now doesn't work right because it grabs *everything* between the very first carrot and the very last carrot. Can anyone think of a loop to wrap around what I've got to grab the correct stuff between carrots? Heck, I don't care if it's totally different code... just as long as it works.
