Question

我正在尝试从以下HTML源代码中提取包含字符串“Active”的Item。请注意，活动项目可能会先行。

这是我正在使用的REGEX（试图非贪婪）：

<TR class=\\w*?Item>.*?Active.*?</TD></TR>

使用Pattern.CASE_INSENSITIVE | Pattern.DOTALL | Pattern.MULTILINE

它提取整个源代码而不是第二个：...

HTML源代码：

<TR class=Item>

我们将非常感谢您的帮助！

Answer 1

*?是zero or more times。您可能需要<TR class=\\w+?Item>

Answer 2

您可以按Pattern p = Pattern.compile("....", Pattern.MULTILINE);启用多行模式您可能需要在模式中将</TD></TR>更改为</TD>.*?</TR>。

Java正则表达式非贪婪不起作用
