New page

{{userfunc}} 
<center>'''strfindt''' ''- by [[user:Mikk|Mikk]] -''</center>


A thin wrapper for [[API strfind|strfind]] that returns the results as a table, allowing it to be used in e.g. if() clauses while capturing subexpressions.


nBeginPos, nEndPos = ''<PREFIX>''_strfindt(tableCaptures, strHaystack, strRegex, nStartPos, boolPlain)

== Function Parameters ==

=== Arguments ===

:(tableCaptures, strHaystack, strRegex, nStartPos, boolPlain)

:;tableCaptures : '''output''' Table - captured subexpressions
<small>(identical to [[API strfind|strfind]]() after this point)</small>
:;strHaystack : String - the string to perform the search in
:;strRegex : String - the regular expression (search pattern)
:;nStartPos : Number - the position to begin the search on (nil = from the beginning)
:;boolPlain : Boolean - set to ''true'' to not use regexes (which defeats the whole purpose of this wrapper)

=== Returns ===

:nBegin, nEnd

:;nBeginPos : Number - beginning of match (1-based) or nil for no match
:;nEndPos: String - end position of match

== Example ==
local results = {};
if(''<PREFIX>''_strfindt(results,
'<b><a href="wowwiki.com">WoWWiki</a>',
'<a [^>]*%fhref="([^"]*)"[^>]>([^<])+</a>')
then
print results[2] . " lives at " . results[1];
end

====Result====
WoWWiki lives at wowwiki.com

==Code==
-- Returns: nBeginPos, nEndPos. Captured expressions go in tOut
function ''<PREFIX>''_strfindt(tOut, strFind, strRegex, nStart, bPlain)
local a = { string.find(strFind, strRegex, nStart, bPlain) };
while(getn(tOut)>0) do tremove(tOut,1); end
for _,v in a do
tinsert(tOut, v);
end
return a[1], a[2];
end
