Branch Reset Group(?|\s*(?|(?|(\/)([^\/]*)[\/]|(_)([^,=]+)|()([^,=]+))(?(?==)\=([^,]+)))\s*,?)+?

+?repeats the group contents below at least once:

\s*any whitespace character, repeated any number of times

Branch Reset Group(?|(?|(\/)([^\/]*)[\/]|(_)([^,=]+)|()([^,=]+))(?(?==)\=([^,]+)))

Branch Reset Group(?|(\/)([^\/]*)[\/]|(_)([^,=]+)|()([^,=]+))

1st Alternative(\/)([^\/]*)[\/]

Group 1(\/)

\/the literal / (47₁₀ / 57₈ / 2F₁₆)

Group 2([^\/]*)

Negated Character Class[^\/]*

*matches any number of characters outside the set below:

\/the literal / (47₁₀ / 57₈ / 2F₁₆)

Character Class[\/]

\/the literal / (47₁₀ / 57₈ / 2F₁₆)

2nd Alternative(_)([^,=]+)

Group 1(_)

_the literal _ (95₁₀ / 137₈ / 5F₁₆)

Group 2([^,=]+)

Negated Character Class[^,=]+

+matches at least one character outside the set below:

,the literal , (44₁₀ / 54₈ / 2C₁₆)

=the literal = (61₁₀ / 75₈ / 3D₁₆)

3rd Alternative()([^,=]+)

Group 1() — does not consume characters

Group 2([^,=]+)

Negated Character Class[^,=]+

+matches at least one character outside the set below:

,the literal , (44₁₀ / 54₈ / 2C₁₆)

=the literal = (61₁₀ / 75₈ / 3D₁₆)

Condition(?(?==)\=([^,]+))

Uses the first branch if the lookaround matches

Positive Lookahead(?==)

=the literal = (61₁₀ / 75₈ / 3D₁₆)

If the condition is true, match this branch:\=([^,]+)

\=the literal = (61₁₀ / 75₈ / 3D₁₆)

Group 3([^,]+)

Negated Character Class[^,]+

+matches at least one character outside the set below:

,the literal , (44₁₀ / 54₈ / 2C₁₆)

\s*any whitespace character, repeated any number of times

,?optionally matches the literal , (44₁₀ / 54₈ / 2C₁₆)

Global pattern flags
