Extract part of a regex match

阅读更多关于 Extract part of a regex match

I want a regular expression to extract the title from a HTML page. Currently I have this: title = re.search('<title>.*</title>', html, re.IGNORECASE).group() if title: title = title.replace('<title>', '').replace('</title>', '') Is there a regular expression to extract just the contents of <title> so I don't have to remove the tags? Use ( ) in regexp and group(1) in python to retrieve the captured string ( re.search will return None if it doesn't find the result, so don't use group() directly ): title_search = re.search('<title>(.*)</title>', html, re.IGNORECASE) if title_search: title = title

问题 I\'d like to extract the text from an HTML file using Python. I want essentially the same output I would get if I copied the text from a browser and pasted it into notepad. I\'d like something more robust than using regular expressions that may fail on poorly formed HTML. I\'ve seen many people recommend Beautiful Soup, but I\'ve had a few problems using it.
