class TOKENIZED_STEPS_VS_XPATH_STRING

(source code)

description

Compare XML processing using tokenized xpaths in class EL_CREATEABLE_FROM_XPATH_MATCH_EVENTS versus using a regular string path in EL_BUILDABLE_FROM_XML.

notes

BENCHMARKS

Add total file sizes from Rhythmbox database using

  1. TOKENIZED_FILE_SIZE_SCANNER
  2. REGULAR_FILE_SIZE_SCANNER

Passes over 10000 millisecs (in descending order)

Tokenized xpaths :  53.0 times (100%)
Regular xpaths   :  41.0 times (-22.6%)
