New submission from Steve Newcomb: The '\\g<startquote>' in the below does not work:
>>> repr( re.compile( '\\<\\!ENTITY[ \\011\\012\\015]+\\%[ >>> \\011\\012\\015]*(?P<entityName>[A-Za-z][A-Za-z0-9\\.\\-\\_\\:]*)[ >>> \\011\\012\\015]*(?P<startquote>[\\042\\047])(?P<entityText>.+?)\\g<startquote>[ >>> \\011\\012\\015]*\\>', re.IGNORECASE | re.DOTALL).search( '<!ENTITY % >>> m.mixedContent "( #PCDATA | i | b)">')) 'None' In the following, the '\\g<startquote>' has been replaced by '\\2'. It works. >>> repr( re.compile( '\\<\\!ENTITY[ \\011\\012\\015]+\\%[ >>> \\011\\012\\015]*(?P<entityName>[A-Za-z][A-Za-z0-9\\.\\-\\_\\:]*)[ >>> \\011\\012\\015]*(?P<startquote>[\\042\\047])(?P<entityText>.+?)\\2[ >>> \\011\\012\\015]*\\>', re.IGNORECASE | re.DOTALL).search( '<!ENTITY % >>> m.mixedContent "( #PCDATA | i | b)">')) '<_sre.SRE_Match object at 0x7f77503d1918>' Either this feature is broken or the re module documentation is somehow misleading me. (Yes, I know there is an XML error in the above. That's because it's SGML.) ---------- components: Regular Expressions messages: 170605 nosy: ezio.melotti, mrabarnett, steve.newcomb priority: normal severity: normal status: open title: backreference to named group does not work type: behavior versions: Python 2.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue15956> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
