问题
I need to get the content of an infobox of any movie. I know the name of the movie. One way is to get the complete content of a Wikipedia page and then parse it until I find {{Infobox and then get the content of the infobox.
Is there any other way for the same using some API or parser?
I am using Python and the pywikipediabot API.
I am also familiar with the wikitools API. So instead of pywikipedia if someone has solution related to the wikitools API, please mention that as well.
回答1:
Instead of reinventing the wheel, check out DBPedia, which has already extracted all Wikipedia infoboxes into an easily parsable database format.

Another great MediaWiki parser is mwparserfromhell.
In [1]: import mwparserfromhell
In [2]: import pywikibot
In [3]: enwp = pywikibot.Site('en','wikipedia')
In [4]: page = pywikibot.Page(enwp, 'Waking Life')
In [5]: wikitext = page.get()
In [6]: wikicode = mwparserfromhell.parse(wikitext)
In [7]: templates = wikicode.filter_templates()
In [8]: templates?
Type: list
String Form:[u'{{Use mdy dates|date=September 2012}}', u"{{Infobox film\n| name = Waking Life\n| im <...> critic film|waking-life|Waking Life}}', u'{{Richard Linklater}}', u'{{DEFAULTSORT:Waking Life}}']

Don't forget that params are mwparserfromhell objects too!

You can get the wikipage content with pywikipdiabot, and then, you can search for the infobox with regex, a parser like mwlib [0], or even stick with pywikipediabot and use one of his template tools. For example on textlib you'll find some functions to deal with templates (hint: search for "# Functions dealing with templates"). [1]
