Regex selecting only first element

Question

I'm printing user song from my server like this:

<id>0000</id>
<song>Song 1</song>
<id>1111</id>
<song>Song 2</song>
<id>2222</id>
<song>Song 3</song>

I'm using regex to get all IDs into array with this pattern <id>(.*?)<\/id> but it's only selecting first ID (<id>0000</id>). Why it isn't selecting all IDs?

NSArray *song_id = [user matchWithRegex:@"<id>(.*?)<\/id>"];

Don't parse XML or HTML with regex. Use a DOM parser instead. — Ken White, Apr 09 '16 at 18:13
You probably don't have the multiline and/or global flag set. You'll have to show your code and tell which regex engine (=language) you're using. — JJJ, Apr 09 '16 at 18:17
Most likely because you didn't tell it you were using multi-line text. — Ken White, Apr 09 '16 at 18:17

Multiline approach with regular expressions:

^<id>(.+?)</id>$

But mandatory: use a parser instead.
See a demo on regex101.com.
