Javascript Regex多行无法正常工作

Question

Given the code:

var regExGroup = new RegExp("\\[group(.*)\\][\s\S]*\\[/group]", 'gi');
var regExResGroup;
while ((regExResGroup = regExGroup.exec(result)) !== null) {
    console.log(regExResGroup[0]);
}

And the test data (the value of result ):

[comment]This is a comment[/comment][group title="This" description="That"]
[comment]This is a comment[/comment]
[event]
[condition object="Touch"]On touch[/condition]
[condition object="Touch"]On touch[/condition]
[action object="Sprite"]Destroy[/action]
[action object="Sprite"]Destroy[/action]
[comment]This is a comment[/comment]
[event]
[condition object="Touch"]On touch[/condition]
[condition object="Touch"]On touch[/condition]
[action object="Sprite"]Destroy[/action]
[action object="Sprite"]Destroy[/action]
[/event]
[/event]
[group title="This" description="That"]
[event]
[condition object="Touch"]On touch[/condition]
[condition object="Touch"]On touch[/condition]
[action object="Sprite"]Destroy[/action]
[action object="Sprite"]Destroy[/action]
[event]
[condition object="Touch"]On touch[/condition]
[condition object="Touch"]On touch[/condition]
[action object="Sprite"]Destroy[/action]
[action object="Sprite"]Destroy[/action]
[/event]
[/event]
[/group]
[/group]

Why is no match being found?

Answer 1

Multiline is m , not g . g is for global, to match all instances of the regular expression. Otherwise it would only match once .

new RegExp("\\[group(.*)\\][\s\S]*\\[/group]", 'gim');

Answer 2

I guess you could try one of these quoting/delimiter options

 #  (?s)\[group(.*?)\].*?\[/group\]
 # /(?s)\[group(.*?)\].*?\[\/group\]/
 # '/(?s)\[group(.*?)\].*?\[\/group\]/'
 # "(?s)\\[group(.*?)\\].*?\\[/group\\]"
 # 

 (?s)
 \[group
 ( .*? )
 \]
 .*? 
 \[/group\]
