360:       end
361:     rescue EOF
362:     end
find_next(byte_list)

Move the pointer so it points to the next byte in a set of possible bytes

     # File lib/feed_tools/vendor/html5/lib/html5/inputstream.rb, line 401
401:     def find_next(byte_list)
402:       until byte_list.include?(current_byte)
403:         @position += 1
404:       end
405:     end
jump_to(bytes)

Look for the next sequence of bytes matching a given sequence. If a match is found advance the position to the last byte of the match

     # File lib/feed_tools/vendor/html5/lib/html5/inputstream.rb, line 389
389:     def jump_to(bytes)
390:       new_position = self[position .. -1].index(bytes)
391:       if new_position
392:         @position += (new_position + bytes.length-1)
393:         return true
394:       else
395:         raise EOF
396:       end
397:     end
match_bytes(bytes, lower=false)

Look for a sequence of bytes at the start of a string. If the bytes are found return true and advance the position to the byte after the match. Otherwise return false and leave the position alone

     # File lib/feed_tools/vendor/html5/lib/html5/inputstream.rb, line 379
379:     def match_bytes(bytes, lower=false)
380:       data = self[position ... position+bytes.length]
381:       data.downcase! if lower
382:       rv = (data == bytes)
383:       @position += bytes.length if rv == true
384:       return rv
385:     end
skip(chars=SPACE_CHARACTERS)

Skip past a list of characters

     # File lib/feed_tools/vendor/html5/lib/html5/inputstream.rb, line 370
370:     def skip(chars=SPACE_CHARACTERS)
371:       while chars.include?(current_byte)
372:         @position += 1
373:       end
374:     end
