Hi all.
A while back I wrote a function that would remove all characters from a string
except for 0-9, a-z, and A-Z. I have updated it to also include an arguement
for other allowed characters, and true or false for line breaks and or carriage
returns. Note the code below. What I need is a list of reserved regex
characters, like backslash (\) and whatnot.
Once tuned up it can be added to the Master Library (I think an older version
may be there already).
function cleanASCII pString, pAllowedChars, pAllowBreaks
put "*|\" into lReservedChars
put pAllowedChars into tCharList
repeat for each char tChar in pAllowedChars
if tChar is in lReservedChars then replace tChar with "\" & tChar in
tCharList
end repeat
if pAllowBreaks is empty then put false into pAllowBreaks
put "[ 0-9A-Za-z]" into tMatchText
put tCharList after char 2 of tMatchText
if pAllowBreaks then
put "\r\n" after char 1 of tMatchText
end if
repeat for each character theChar in pString
/* if theChar is "|" then
put theChar after cleanString -- special case for regex reserved char
next repeat
end if
*/
if matchtext(theChar, tMatchText) is true then
put theChar after cleanString
end if
end repeat
return cleanString
end cleanASCII
