我正在尝试从 Objective-c 中的 MediaWiki 获取某个人的详细信息。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
我收到的数据如下：
</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}}

现在我想在objective-c中获得该人的生日。不知何故，我也可以设法获得birth_date。但我的问题是，是否可以使用任何正确的解析来解析这些数据？
答案 0 :(得分：2)
这不是方法。将Web API与某些client library一起使用。更好的是，使用正确的 API，即 - 对于数据问题 - 维基数据。
