Function: text.replace_all_regex

Replaces all matches of a regular expression with a new string.

In the case of overlapping matches, the leftmost instance is replaced and if multiple matches start at the same index, then the longest one is replaced. If the expression is empty, it matches at the beginning of the string and after each code point, yielding up to k+1 replacements for a string with k code points.

Note that regular expression backreferences are not supported and you can't refer to text previously matched by a capturing group.

Arguments

Arguments
source	string The subject of the function. A modified copy is returned.
regexp	string The regular expression used for matching substrings. Uses RE2 syntax.
repl	string The string that will replace all matches of regexp. Backreferences are not supported. For example, you can't use the expression \1 to refer to text previously matched by a capturing group.

Returns

A copy of source where all matches of regexp are replaced by repl.

Raised exceptions

Exceptions
TypeError	If either source, regexp, or repl is not a string.
ValueError	If either regexp or repl is not UTF-8 encoded or if regexp is an invalid regular expression.
