Default related to regular expression

I would like to know regular expression(s):

    1. to find all the occurences of <img> tags (in HTML text)
          that are enclosed within <a> tags like <a><img /></a>

    2. to find all the occurences of [b]<img> tags (in HTML text)
          that are not enclosed within <a> tags

I'd probably reccommend using a proper html parser. If thats' not practical you'd want something like (this is in perl):
Code:
#!/usr/bin/perl

while(<>) {
  print "Image found $1" if (/(<img[^>]+>)/);
  print "Image within 'a' tag: $1" if (/<a[^>]+>(<img[^>]+>)<\/a>/);
}
This won't work on multi-line 'a' tags and so on, but it'll get you started.
