Ich habe eine Zeichenfolge mit unzulässigen Zeichen, die ich entfernen möchte, aber ich weiß nicht, welche Art von Zeichen vorhanden sein könnten.
Ich habe eine Liste von Zeichen erstellt, die nicht gefiltert werden sollen, und ich habe dieses Skript erstellt (auf der Grundlage eines anderen Skripts, das ich im Internet gefunden habe).
on clean_string(TheString)
--Store the current TIDs. To be polite to other scripts.
set previousDelimiter to AppleScript's text item delimiters
set potentialName to TheString
set legalName to {}
set legalCharacters to {"a", "b", "c", "d", "e", "f",
"g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r",
"s", "t", "u", "v", "w", "x", "y", "z", "A", "B", "C", "D", "E",
"F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R",
"S", "T", "U", "V", "W", "X", "Y", "Z", "1", "2", "3", "4", "5",
"6", "7", "8", "9", "0", "?", "+", "-", "Ç", "ç", "á", "Á", "é",
"É", "í", "Í", "ó", "Ó", "ú", "Ú", "â", "Â", "ã", "Ã", "ñ", "Ñ",
"õ", "Õ", "à", "À", "è", "È", "ü", "Ü", "ö", "Ö", "!", "$", "%",
"/", "(", ")", "&", "€", "#", "@", "=", "*", "+", "-", ",", ".",
"–", "_", " ", ":", ";", ASCII character 10, ASCII character 13}
--Whatever you want to eliminate.
--Now iterate through the characters checking them.
repeat with thisCharacter in the characters of potentialName
set thisCharacter to thisCharacter as text
if thisCharacter is in legalCharacters then
set the end of legalName to thisCharacter
log (legalName as string)
end if
end repeat
--Make sure that you set the TIDs before making the
--list of characters into a string.
set AppleScript's text item delimiters to ""
--Check the name's length.
if length of legalName is greater than 32 then
set legalName to items 1 thru 32 of legalName as text
else
set legalName to legalName as text
end if
--Restore the current TIDs. To be polite to other scripts.
set AppleScript's text item delimiters to previousDelimiter
return legalName
end clean_string
Das Problem ist, dass dieses Skript verdammt langsam ist und mir eine Zeitüberschreitung beschert.
Ich prüfe Zeichen für Zeichen und vergleiche sie mit der Liste legalCharacters. Wenn das Zeichen vorhanden ist, ist es in Ordnung. Wenn nicht, ignorieren.
Gibt es eine schnelle Möglichkeit, dies zu tun?
etwas wie
"jedes Zeichen von TheString untersuchen und diejenigen entfernen, die nicht in legalCharacters enthalten sind"
?
danke für jede Hilfe.
