Question

我正在尝试从以下HTML中的标签中提取文本作为项目符号。我的代码打印它的方式是一个带有一些不必要文本的连续字符串。我看到我可以做一个replace("<br>","\n")，但在这种情况下没有用，我随身携带了Google HTML数据。

<div class="report-content" style="line-height:160%!important"> Read the side effects of Abacavir as described in the medical literature. In case of any doubt consult your doctor or pharmacist.

Answer 1

<br>被称为empty element，这意味着无法包含数据。因为它是一个空元素，<br>和<br/>的行为方式相同：它们会立即关闭。它们不（也不能）包含数据。该文字由封闭的<div>和.report-content类包含。
