javascript - Regex Group Capture

I have a standard email which I am looking to extract certain details from.

Amongst the email are lines like so:

Name: John Smith

So to simulate this I have the following JavaScript:

var str = "
Name: John Smith
";
var re = /\Name\s*:\<\/strong>\s*([^\<]*)/g
match = re.exec(str);
while (match != null) {
    console.log(match[0]);
    match = re.exec(str);
}

This only comes out with one result, which is:

Name: John Smith

I was hoping to get the capture group ([^\<]*) which in this example would be John Smith

What am I missing here?

Answer

Capture groups are provided in the match array starting at index 1:

var str = "
Name: John Smith
";
var re = /\Name\s*:\<\/strong>\s*([^\<]*)/g
match = re.exec(str);
while (match != null) {
    console.log(match[1]); // <====
    match = re.exec(str);
}

Index 0 contains the whole match.

On modern JavaScript engines, you could also use named capture groups ((?...), which you can access via match.groups.theName:

var str = "
Name: John Smith
";
var re = /\Name\s*:\<\/strong>\s*(?[^\<]*)/g
// ---------------------------------------^^^^^^^
match = re.exec(str);
while (match != null) {
    console.log(match.groups.name); // <====
    match = re.exec(str);
}
