Script with different OUTPUT at different runs - Inetread

[vSSC]

Hello.

I have the following script:

#include <string.au3>
$Source = BinaryToString(InetRead('https://www.youtube.com/playlist?list=PL4Jcq5zn02jKpjX0nqI1_fS7mEEb5tw6z', 1))

$FirstChunks = _StringBetween($Source, 'data-title="', '" data-set-video-id=')

For $a In $FirstChunks
    ConsoleWrite($a & @CRLF)
    Next

When i run it: sometimes i get the list of videos i'm intrested in, see run1, and sometimes i get bogus data, see run2.

Any ideas why is this happening?

RUN1:

Hi, just for fun i tried some things and came up with this. It gets the results every time i run the script. a more advanced AutoIT programmer can come up with much better solutions. But ok, it was also for me fun to play a bit with this. I noticed there are some weird chars in the array. Probably [enters-line feeds] or [carriage returns] they caused me some problems. Anyway hope this helps you and perhaps some other people come up with some better idea's.

This should work in both cases

_StringBetween($Source, 'data-title="', '"')
