wikipedia api:仅获取解析介绍

使用 PHP，是否有一种很好的方法可以从维基百科页面唯一获取(解析)介绍?

Using PHP, is there a nice way to get the (parsed) introduction only from a wikipedia page?

我必须采用当前方法:

• 首先是调用api页面并返回，然后在我从第一个请求中提取的介绍上调用Wiki解析器(两个请求，从文本中提取介绍也不漂亮).
• 第二种是调用整个页面解析器，并使用xpath来检索内容表之前的每个
  标签.

• The first is to call the api page and return, then call the Wiki parser on the introduction I have pulled from the first request (two requests, extracting the intro from the text isn't pretty either).
• The second is to call the entire page parser and use xpath to retrieve every <p> tag before the contents table.

使用这两种方法后，我必须重新解析 HTML 以确保介绍链接中的相关链接指向维基百科.

With both methods I then have to re-parse the HTML to ensure the relevant links inside the introduction link off to wikipedia.

两者都不理想，一定有更好的方法吗?

Neither are ideal really, there must be a better way?
