Yeah, AM escapes the wrong chars. Let's put it right. If you say:
$string =~ /<.*>(.*)<\/.*>/;
on a string "<foo>...</foo><bar>...</bar>"
you get everything between "<foo>" and "</bar>",
because the "*" modifier is "greedy", which means it
tries to match as much as possible. A "." in a regex
matches anything, so ".*" matches until the end of the
string. Then the rest of the regex is evaluated, done by
backtracking (the regex machine is now at the end of the
string and goes back one by one until it finds a match).
I hope this was correct.
Damn HTML escaping :) I fixed it, so the strings actually show up.
