维基百科信息框内容

Question

我需要得到任何电影的信息框的内容。我知道这部电影的名字。一种方法是获取Wikipedia页面的完整内容，然后对其进行解析，直到找到{{Infobox，然后获取infobox的内容。

有没有其他的方法来使用API或解析器呢？

我正在使用Python和pywikipediabot API。

我还熟悉wikitools的API。因此，如果有人有与wikitools API相关的解决方案，请不要使用pywikipedia，也要提到这一点。

Answer 1

您可以使用pywikipdiabot获取wikipage内容，然后，您可以使用regex（一种类似mwlib[0]的解析器）搜索infobox，甚至可以使用pywikipediabot并使用他的一个模板工具。例如，在textlib上，您可以找到一些处理模板的函数（提示：搜索“#处理模板的函数”）。[一]

Answer 2

与其重新发明轮子，不如查看DBPedia，它已经将所有维基百科信息框提取为一种易于解析的数据库格式。

Answer 3

另一个伟大的MediaWiki解析器是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}}']
Length:     31
Docstring:
list() -> new empty list
list(iterable) -> new list initialized from iterable's items

In [10]: templates[:2]
Out[10]:

In [11]: infobox_film = templates[1]

In [12]: for param in infobox_film.params:
             print param.name, param.value

别忘了params也是mwparserfromhell对象！
