I think I have a solution, but if a few of you could review and see if it can
be any faster or more efficient (or if I'm missing something) I'd appreciate
it. To find the end of the URL I'm looking for a single quote, double quote or
space.
function extractURLs(inputString) {
var nPos=0;
var lsURLs = "";
var sDelimiter = chr(9);
var nEndPos = "";
var sLink = "";
var sRegExp =
"([A-Za-z][A-Za-z0-9+.-]{1,120}:[A-Za-z0-9/](([A-Za-z0-9$_.+!*,;/?:@&~=-])|%[A-Fa-f0-9]{2}){1,333}(##([a-zA-Z0-9][a-zA-Z0-9$_.+!*,;/?:@&~=%-]{0,1000}))?)";
if(arrayLen(arguments) eq 2) {
sDelimiter = arguments[2];
}
nPos = reFindNoCase(sRegExp,inputString);
while(nPos) {
inputString = mid(inputString,nPos,len(inputString));
nEndPos = reFind("['#chr(34)# ]",inputString);
sLink = left(inputString,nEndPos-1);
if(NOT listFindNoCase(lsURLs,sLink,sDelimiter)) {
lsURLs = listAppend(lsURLs, sLink, sDelimiter);
}
inputString = mid(inputString,nEndPos,len(inputString));
nPos = reFindNoCase(sRegExp,inputString);
}
return lsURLs;
}
Thanks!
