Preserved Topic: Simple RegExp (Page 1 of 1)

This question goes to anyone on the Asulym, but i KNOW the guru mr.MaX will solve it for me :-]

I have random URL´s that I want to remove the last file from...

ex. http://www.someserver.com/somefolder/file.html
would be: http://www.someserver.com/somefolder

How do I do that with a simple regExp?

Thanks in advance

Smash!

<SCRIPT TYPE="text/javascript" LANGUAGE="JavaScript">
<!-- ;

// Written by mr.maX, http://www.max.co.yu/

maxURL = "http://www.someserver.com/somefolder/file.html";
maxURL = maxURL.replace(/[^\/]+$/ig, "");
document.write(maxURL);

// -->
</SCRIPT>

Enjoy!

Dammit MAX! I could have actualy answered that one! heh

My turn now

Yet a simpler one:

url = "http://www.someserver.com/somefolder/file.html".match(/(.+?)[^/]+$/i);

document.write(RegExp.$1);

Now mr.Max your turn again!

Me and crossbrowsers! this won't work on ShiftScape!

why?!

other than escaping the / in [^/] like [^\/]...

I want the same RegExp but want to know why ShiftScape doesn't work!

Lallous, actually your code isn't simpler than mine. Only thing that you did is condense functions, but your RegEx is still more complex than mine. Anyway, I won't go into cross browser issues since I don't have time.

BTW This is my code in condensed form:

document.write("http://www.someserver.com/somefolder/file.html".replace(/[^\/]+$/ig, ""));

Short, isn't it?

I now beleive that NetScape doesnt fully support PCRE (Perl Compatible Regular Expression) as opposite to JavaScript, PHP, Delphi's TRegExpr unit, and many other RegExps librarys that i'm testing on!

I'm not gonna dive too into solving the matter of ShiftScape (as you call it)....

As for your approach for Smash's question..well it's not a good use of RegExps as you did!
...it could be solved the same way without RegExps:

str = "http://www.someserver.com/somefolder/file.html";

 document.write(str.substr(0, str.lastIndexOf("/")+1));

Of course that it can be done using only string handling functions, but he asked for RegEx and I wrote it...

of course mr.Max but what I really mean that using the Replace method is not the optimal way to extract information...it should have been a pure Regular expression that extracts the info...

IMHO Matching part of the string that should be excluded is more efficient in this case (especially since filename will be shorter than the rest of the URL)...
