iphone - 从 mediawiki xml 格式 api 获取生日、出生地

Question

我试图从 Objective-c 中的 MediaWiki 获取一个人的详细信息。我正在使用 http://en.wikipedia.org/w/api.php?action=query&prop=revisions&rvprop=content&rvsection=0&titles=Albert_Einstein&format=xml

我得到的响应数据如下:

</i>$0 = 0x07562e60 <?xml version="1.0"?><api><query><normalized><n     from="Albert_Einstein" to="Albert Einstein" /></normalized><pages><page pageid="736" ns="0" title="Albert Einstein"><revisions><rev contentformat="text/x-wiki" contentmodel="wikitext"     xml:space="preserve">{{Redirect|Einstein}}
{{Good article}}
{{pp-semi|small=yes}}{{pp-move-indef}}
{{Infobox scientist
| name        = Albert Einstein
| image       = Einstein 1921 by F Schmutzer.jpg
| caption     = Albert Einstein in 1921
| birth_date  = {{Birth date|df=yes|1879|3|14}}
| birth_place = [[Ulm]], [[Kingdom of Württemberg]], [[German Empire]]
| death_date  = {{Death date and age|df=yes|1955|4|18|1879|3|14}}
| death_place = {{nowrap|[[Princeton, New Jersey|Princeton]], [[New Jersey]], U.S.}}

| residence   = Germany, Italy, Switzerland, Austria, Belgium, United States
| citizenship = {{Plainlist|

现在我想在 objective-c 中获取这个人的生日。我也可以设法以某种方式获得出生日期。但我的问题是，是否有任何适当的解析可用于解析这些数据？

Answer 1

这不是方法。将 Web API 与一些 client library 结合使用.更好的是，使用适当的 API，即 – 对于数据问题 – Wikidata 的。

参见 wbgetclaims docs和示例:https://www.wikidata.org/w/api.php?action=wbgetclaims&entity=Q937&property=P569给
