ReFind

Uses a regular expression (RE) to search a string for a pattern, starting from a specified position.

The search is case-sensitive. It will return numeric if returnsubexpressions is false and a struct of arrays named "len", "match" and "pos" when returnsubexpressions is true.

Method Signature

ReFind(reg_expression=[string], string=[string], start=[integer], returnSubExpressions=[boolean], scope=[string])

Arguments

Argument Type Required Description Default

Argument	Type	Required	Description	Default
`reg_expression`	`string`	`true`	The regular expression to search for
`string`	`string`	`true`	The string to serach in
`start`	`integer`	`false`	The position from which to start searching in the string. Default is 1.	`1`
`returnSubExpressions`	`boolean`	`false`	True: if the regular expression is found, the first array element contains the length and position, respectively, of the first match. If the regular expression contains parentheses that group subexpressions, each subsequent array element contains the length and position, respectively, of the first occurrence of each group. If the regular expression is not found, the arrays each contain one element with the value 0. False: the function returns the position in the string where the match begins. Default.	`false`
`scope`	`string`	`false`	"one": returns the first value that matches the regex. "all": returns all values that match the regex.	`one`
