I’m converting my forum to phpBB and they use similar BBCode tag but one is different. To quote in the old forum, it was formatted like:
old: [quote=prattw]My text here.[/quote]
new: [quote=”prattw”]My text here.[/quote]
I need a regex that will add the quotes around the username in the BBCode block. Many thanks!
Assuming that the only valid characters for usernames are those matched by
\w, i.e.[a-zA-Z0-9_](in Python), then you can replace\[quote=(\w+)\]by\[quote="\1"\].Caveats:
if your usernames are permitted to contain
[]this may go horribly wrong.\[quote=(.+?)\], but for[quote=Clan[FROZEN] Supahkillah]this would give the matchClan[Froze.\[quote=(.+)\]would match too much of[quote=Alice][quote=Bob].Remember that regexps aren’t good at handling nested structures. You may want to use a parsing approach instead of a regular expression approach. (For HTML, this would be “use an XML parser” – for this example it will be “use a bbCode parser”.)
At least in Python, the meaning of
\wis locale-dependent. So for Russians,\wwould match things likeГлавное в новостяхtoo.I still think you’re trying to reinvent the wheel. Chances are that a script exists to automatically convert your old forum format to phpBB – you just have to look for it.
