is there any faster way to parse a text than by walk each byte of the text?

I wonder if there is any special CPU (x86/x64) instruction for string operation that is used by string library, that somehow used to optimize the parsing routine.

for example instruction like finding a token in a string that could be run by hardware instead of looping each byte until a token is found.
