Returns the right side of a delimited string preserving the rest of the string which may contain the same delimiter. Useful when the delimiters are duplicated in the same string, like colon's in a URL string for example and you want to parse out only one. The string is parsed from the start position which is a zero based index e.g. "http://xyz.com:7001/" will return "//xyz.com:7001/" if startPos = 0 or "7001/" if startPos > 4 and < 13 If the string cannot be parsed the original string will be returned.

str -

delimiter -

startPos - (zero based)

Returns:

parsed string or original if it cannot be parsed
