正则表达式查找特定字符串的所有出现两条线

Question

之间，我想两线之间，例如搜索特定字符串的所有出现

some line nobody is interested in 
this is the beginning 
this is of no interest 
attention 
not interesting 
this is the ending 

正则表达式如何在“这是开始”和“这是结束”之间寻找“注意”？有没有办法实现这一点？此正则表达式的

Answer 1

尝试组1：

(?s)this is the beginning.*?(attention).*?this is the ending 

FYI (?s)打开 “点匹配换行符”

Answer 2

交易所"=="你需要匹配

bool foundStart = false; 
for line in lines{ 
    if (line == "this is the beginning") 
     foundstart = true; 
    else if(line == "this is the ending") 
     foundstart = false; //set to false if could come beginning again 
     break; //or break directly 
    else if (foundstart && line == interestingpattern) 
     interesting_lines.Add(line); 
} 

或正则表达式的任何模式如果是这样，你只需要“有趣”一个次数：

re1='.*?' # Non-greedy match on filler 
re2='(start)' # Word 1 //exchange to your pattern for start 
re3='.*?' # Non-greedy match on filler 
re4='(interesting)' # Word 2/Exchange to your pattern for interesting 
re5='.*?' # Non-greedy match on filler 
re6='(end)' # Word 3 // exchange to your ending pattern 

然后编译(re1+re2+re3+re4+re5+re6)，并采取了只RE4

试试这个

var test = "some line nobody is interested in this is the beginning this is of no interest attention not interesting this is the ending"; 

var testRE = (test.match("this is the beginning (.*) this is the endin")); 
alert(testRE[1].match(/attention/g).length);
