Java正则表达式提取两个标记之间的任何字符

Question

我正在尝试解析以下文本

### __Description of the report__
Lorem ipsum dolor sit amet,  & mauris elit, blandit a turpis vel nibh, 
consectetuer aliquam. Nec sem. Venenatis quam etiam donec consequat 
sagittis, luctus porttitor odit sollicitudin <> vestibulum ultrices erat,
sed eleifend 
* amet, sollicitudin sit egestas 
* quis eros nulla. Sed donec

### __Notable filters__
* Lorem ipsum dolor sit amet, mauris elit, blandit a turpis vel
* consectetuer aliquam. Nec sem. Venenatis quam etiam donec consequat 
* sagittis, luctus porttitor odit sollicitudin vestibulum ultrices 

我想捕获 ### __Description of the report__ 和 ### __Notablefilter__ 之间的所有文本，可以是数字、字母或特殊字符的任意组合。

我认为使用 ### __Description of the report__(.*?)### __Notablefilters__ 会起作用，但它不会返回任何结果。如何提取两个标题之间的文本？

Answer 1

您可以使用字符串的 split 函数并将两个 header 用作正则表达式，并与“|”连接运算符。

这样，第一节的内容将放置在数组的第一个元素中，第二节的内容将放置在数组的第二个元素中。

请检查此代码:

public class Test {
    private String testString = "### __Description of the report__\n" +
"Lorem ipsum dolor sit amet,  & mauris elit, blandit a turpis vel nibh, \n" +
"consectetuer aliquam. Nec sem. Venenatis quam etiam donec consequat \n" +
"sagittis, luctus porttitor odit sollicitudin <> vestibulum ultrices erat,\n" +
"sed eleifend \n" +
"* amet, sollicitudin sit egestas \n" +
"* quis eros nulla. Sed donec\n" +
"\n" +
"### __Notable filters__\n" +
"* Lorem ipsum dolor sit amet, mauris elit, blandit a turpis vel\n" +
"* consectetuer aliquam. Nec sem. Venenatis quam etiam donec consequat \n" +
"* sagittis, luctus porttitor odit sollicitudin vestibulum ultrices ";

    public static void main (String[] args)
    {
        Test t = new Test();
        String[] parts = t.testString.split("### __Description of the report__\n|### __Notable filters__\n");
    }
}
