Strfindt

strfindt - by Mikk -

A thin wrapper for 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)

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

(identical to strfind after this point)

• tableCaptures : output Table - captured subexpressions
• 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)

• nBegin, nEnd

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

local results = {}; if(&lt;PREFIX&gt;_strfindt(results, '&lt;b>&lt;a href="wowpedia.org">Wowpedia&lt;/a>', '&lt;a [^>]*%fhref="([^"]*)"[^>]>([^<])+&lt;/a>') then print results[2] . " lives at " . results[1]; end

Wowpedia lives at wowpedia.org

-- Returns: nBeginPos, nEndPos. Captured expressions go in tOut function &lt;PREFIX&gt;_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
