That means no nested elements. And if you want to do a finite number of nested elements, you have to write one regex for each level. This requirement alone should kill most general purposes. Specially crafted scripts, on the other hand, are easily adapted. > Those regular expressions aren't going > away. Helping them break less is a noble cause. I would argue exactly the opposite: Making stupid invalid parsers break more would encourage people to use the right facilities. And we are not even talking about achieving that: ">" in attributes was here for years, and it is here to stay.
