@Purpose: This is a totally revised version of my previous 2013 gist: |
|
GetYouTubeTagsAsCSV. In the almost 2 years since, YouTube has |
|
changed the way tags are stored, once again. Currently the |
|
tags are being held in the Meta value "keywords", so what I'many |
|
doing is grabbing the content, which is ALREADY IN CSV form. So, |
|
what else did I do to make this more useful? Not much... Just |
|
using a for loop to list each keyword (with quotes and |
|
preceding/trailing spaces stripped), numbered, on its own line. |
|
|
|
For some reason, YouTube isn't listing all the keywords in the |
|
meta tag; they are chopped off--probably using a max_character_count |
|
type of variable--and the last displayed keyword has an ellipsis |
|
appended. To go further, I discovered that the keywords are being |
|
stored as json, but I'm not a json expert and supper awaits, so |
|
grabbing *ALL* the keywords could be done if I could figure out how |
|
to handle the json... perhaps that will be the next revision. |
|
|
|
Overall, I'm pretty happy with how simple this was to write. Enjoy! :) |
