./⁠wp-⁠includes/⁠rss.php (change row 117)

php5: list($ns, $el) = split( ':', $element, 2);
php7: list($ns, $el) = preg_split( ':', $element, 2);

Replying to frymi:

./⁠wp-⁠includes/⁠rss.php (change row 117)

See also:
./wp-includes/atomlib.php line 316

Since this split does not need regex, I recommend using explode() instead. Patch attached.
