两个字符串之间的模式在java中(Pattern between two string in java)

两个字符串之间的模式在java中(Pattern between two string in java)

我有一个长字符串，形式如下：

如何在<DETAIL>和</TEXT>之间提取数据，请注意它不是一个xml文件。 每个结局后都会有一个新行。 我尝试了以下方法：

Pattern pattern = Pattern.compile("<DETAIL>(.*?)</TEXT>"); Matcher matcher = pattern.matcher(string); while (matcher.find()) { System.out.println(matcher.group(1)); }

它给了我空值，任何人都可以帮忙吗？ 提前致谢。

I have a long string which is of the form:

How can i extract the data between <DETAIL> and </TEXT>, note that its NOT an xml file. There is a new line after every ending. I tried the following :

Pattern pattern = Pattern.compile("<DETAIL>(.*?)</TEXT>"); Matcher matcher = pattern.matcher(string); while (matcher.find()) { System.out.println(matcher.group(1)); }

It gives me null values, any one can help ? Thanks in advance.

最满意答案

默认情况下. 与换行符不匹配。

使用s标志（ DOTALL ）来制作. 匹配到换行符。

Pattern pattern = Pattern.compile("(?s)<DETAIL>(.*?)</TEXT>");

要么

Pattern pattern = Pattern.compile("<DETAIL>(.*?)</TEXT>", Pattern.DOTALL);

By default, . does not match newline.

Use s flag (DOTALL) to make . match to newline.

Pattern pattern = Pattern.compile("(?s)<DETAIL>(.*?)</TEXT>");

or

Pattern pattern = Pattern.compile("<DETAIL>(.*?)</TEXT>", Pattern.DOTALL);
