Question

我需要从下面的标记中提取文本76和Houses, Apartments for Rent in。如何使用Jsoup选择器执行此操作？

我试过

Elements elem=doc.select("h1Title >span.id");
String Pagetitle=elem.text();

但它没有用。

<div>
  <h1 class = "h1Title">
    <span id='resultsCount'>76</span> Houses, Apartments for Rent in <span id='loc'>Koramangala</span>
  </h1>
</div>

Answer 1

这将为您提供一切：

Elements elem=doc.select(".h1Title");
String pageTitle = elem.text(); //76 Houses, Apartments for Rent in Koramangala

如果您只想要数字：

Elements elem=doc.select(".h1Title #resultsCount");
String pageTitle = elem.text(); // 76

请注意您的所作所为（如果需要，请阅读有关CSS选择器的更多信息）：

h1Title > span.id
element h1Title (for class, put a dot first)
this would work if you had <h1Title>
element span : ok (you have <span>)
class id! the . means class, you would have <span class="id">
for id, use # (see my example)

简而言之：

foo：tag
.foo：class
#foo：id
