Abstract
Delimiter lookup is accomplished using a processor permutation instruction. A 256-bit bitmap is defined and stored within two sixteen-byte registers. Each bit of the bitmap represents an eight-bit character occurrable within a character string, such as a section of eXtensible Markup Language (XML) code, and has a value indicating whether the character is a target character, such as a delimiter. The character string has a number of eight-bit characters at a corresponding number of positions. The first position within the character string at which one of the target characters occurs is determined, using the 256-bit bitmap and a processor permutation instruction. The first position within the character string at which one of the target characters occurs, as has been determined, is output.
