Regex: a string does not starts and ends with the same character

[Melcu54]

hello. I have a little problem with Python and Regex. In fact, some regex doesn't work if a string does not starts and ends with the same character. For example I have this html tags:

pattern1 = r'<p class="text_obisnuit">.*((bebe|oana|mother|sun).*){3,}.*</p>'
pattern2 = r'<p class="text_obisnuit2">.*((bebe|oana|mother|sun).*){3,}.*</p>'
pattern3 = r'<title>.*((bebe|oana|mother|sun).*){3,}.*</title>'
pattern4 = r'<meta name="description" content=.*((bebe|oana|mother|sun).*){3,}.*>'

The first 3 tags are working, because a string is starts and ends with the same character.

But the 4 tag, the one with meta description, is not working. Python cannot find anything with the regex.
