Regular expression hell

[ronobvious]

I've got this string:
Anonymous Login=False;Certificate Validation=ValidateAndAsk;Connect Timeout=60;Connection=Scriptor FTP;Download Folder=C:\Temp;Download Libraries=True;Email Address=[e-mail];Host CCSID=37;List Formats=OS/400 QSYS.LIB;Maximum Simultaneous Transfers=4;Network Address=www.address.com;Network Port=21;NLV=2924;Passive=True;Password=***;Receive Timeout=60;Send Timeout=60;Transfer Options=7;Use Encryption for Data=False;User ID=scriptor

I want to extract the value of "Download Folder". Namely, "C:\temp". I used to be a wiz at this stuff on Unix, but with Javascript I'm missing something. Here's my code:

var s;
var re = new RegExp("/Download Folder=([^;])/g");
var str = App.GetValue("connectionString");
var arr = re.exec(str);

s = str + "\n" + "$1 contains: " + RegExp.$1 + "\n";
s += "$2 contains: " + RegExp.$2 + "\n";
s += "$3 contains: " + RegExp.$3;

I always get zilch. I've tried all kinds of variations I can come up with for the RegExp() pattern; searched the web and tried differing syntaxes. BTW, 'str' is my string above. Got a headache from this; I think I'll go lie down a while. :-)

Thanks!

If str is your string:

alert( str.match(/Download Folder=([^;]+);/i)[1] )
 
// or
 
alert( str.match( new RegExp("Download Folder=([^;]+);","i"))[1] )
 

This will produce "C:Temp" because the '\' is interpreted as the start of an escape sequence. If you need to fix this, you can get the initial string formatted differently as C:\\Temp or C:/Temp or insert / or \ after : if it's missing. It all depends upon what the host system/software can handle.

Worked like a champ. Much thanks for sure!
