[英]How to extract required string in below text using regular expressions in java?
我想在下面的文本的第一个和最后一个之间提取字符串。
方案1:
"Select statement"+"\n"+
"first"+"\n"+
"I want to extract this" +"\n"+
"I want to extract this one too"+"\n"+
"last"+"\n"+
"end of the statement"+"\n"+
"first"+"\n"+
"I want to extract this" +"\n"+
"I want to extract this one too"+"\n"+
"last"+"\n"+
"end of the statement"
方案2:
"Select statement"+"\n"+
"first"+"\n"+
"I want to extract this" +"\n"+
"last"+"\n"+
"end of the statement";
Java中的正则表达式模式可以完成这项工作? 模式应该是一种,但在两种情况下都应该起作用。 谢谢你的帮助。
您可以使用环顾四周。
Matcher m = Pattern.compile("(?s)(?<=\\bfirst\\n).*?(?=\\n?\\blast\\b)").matcher(s);
if(m.find())
{
System.out.println(m.group());
}
