Summary | 0002907: Regex option 'A' ignored | ||||||||
Description |
When a regex expression uses option 'A', the match functions must use the offest specified. I have found this in mediawiki 1.12 code in this expression: $elementsRegex = "~($xmlishRegex)(?:\s|\/>|>)|(!--)~iA"; subsequently used in a call to preg_match with offset specified. |
||||||||
Additional Information |
I think the semantics of option 'A' is to anchor the search to the offset specified relative to the beginning of the text, while option '^' means to anchor to the beginning of the text. I changed the test in RegexpNode.AnchorBegin.match: // if (offset == 0) if (offset == state._first) This solves the problem at least for mediawiki. |
