正则表达式选择HTML标记内的特定字符

Question

I'm only looking for standard tags like p, title, h1, h2 etc.

<[/a]*>content resides in here</[/a]*>

And I'm specifically looking for punctuation marks to combat a potential SQL injection. Also, for this project I am unable to use BeautifulSoup.

Answer 1

Try this regex:

<(a|h1|p|title)[^>]*>([^<]+)</\1[^>]*>

I assume that tags will contain text only, no tags...
Python doesn't support recursive regular expression.
