Explication

This regex pattern matches one or more occurrences of the ' ' tag at the beginning of a string. '^' asserts the position at the start of the string. ' ' matches the literal ' ' tag. '+' matches one or more occurrences of the preceding element. The use of parentheses and the '+' quantifier ensures that it captures and matches multiple ' ' tags at the beginning of the string.
