[PHP] Is there a good way to extract the embed/object content in HTML with/without closing tag?
Hi,
I want to extract all contents started with embed and object
with/without closing tags.
My solution is using a regular expression to get it work, but there is some
exception I could not handle out.
The REGEXs I used are:
// With closing tag
if (preg_match_all(#((object|embed)[^]+.*?/\\2)#is, $str,
$matchObjs)) {
// blahblah
// Without closing tag
} else if (preg_match_all(#((?:object|embed)[^]+)#,$str,$matchObjs)){
// blahblah
}
But it might be failed if the $str are mixed with/without closing tags:
$str ='divdivobject type=application/x-shockwave-flashparam
name=zz value=xx/object/divdivembed src=http://sample.com;
//div'
In this situation, it will only get the
object type=application/x-shockwave-flashparam name=zz
value=xx/object
but I want to get the two results which are
object type=application/x-shockwave-flashparam name=zz
value=xx/object
embed src=http://sample.com; /
So, is there a good way to use one REGEX to process this issue?
Thanks for your help.

Re: [PHP] Multiple Login in a single PC should not be possible
See comment on virtual machine :) But even without a virtual machine, is this SharedObject saved in a browser determined location, or does the flash app get a say on where it wants to go. Is it shared between flash apps in same browser, or shared across all browsers on same machine. Cheers, Rob.

To illustrate, before me now on my 'single' machine, I have the primary OS, and two more running in virtual box's; each one has several browsers; and to compound matters I'm hooked up to 2 different networks; and on one of those I can change IP whenever I want.

If you're open to using methods other than regex; then one way to get
pretty good results is to run the document through HTML Tidy, then parse
it in to a DOM and query it using xpath/xquery - basically mimic the
base way in which the browsers do it (and the way recommended by the
HTML specs)
Best,

Re: [PHP] Multiple Login in a single PC should not be possible
quick confirm: flash won't help you here (nor java, ajax, virtualisation, client side programs, ip filtering, browser detection) - it's not possible I'm afraid; best you can do is limit with personally identifiable information and trust that users won't be sharing an account which has sensitive data in it. I seem to have missed it; but why exactly don't you want a client 'logged in' multiple times (at the same time)? perhaps if you give us the root of the problem instead of how to do the solution you've chosen, we can be of more help :) Best, Nathan Robert Cummings wrote: See comment on virtual machine :) But even without a virtual machine, is this SharedObject saved in a browser determined location, or does the flash app get a say on where it wants to go.

And only allow the test to be taken by a specific login once (ie if they've started it, they can't start again) But doesn't effectively stop anything because they could have 2 user accounts, and all the previous matters. you can make it more difficult, can't prevent it. as far as I know anyway!

Re: [PHP] Multiple Login in a single PC should not be possible
I was given a solution, or a work-around. You will have to use flash, but, you can set up a LocalConnection class that determines if the swf is being run on the same system and if it is boot one. You have the LocalConnection class send out a message to itself and if it answers itself, then there are two running. Otherwise only that one is running. Sort of hackish, but would probably do the trick. HTH Karl On May 23, 2010, at 3:35 PM, Karl DeSaulniers wrote: Hi Nathan, The problem is not mine to speak of necessarily.

If a User has logged on my website website.com in Internet explorer, then he cant login on same website in another browser like Firefox etc with same loginid or another. Can I trace MAC address of a single machine to solve this issue? Or is there a concept of GLOBAL COOKIE / Cross Browser Cookie which will work for all browsers in a single machine.. I hope You will help me out Regards Jagdeep Singh +91 9988009272 Karl DeSaulniers Design Drumm http://designdrumm.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php Karl DeSaulniers Design Drumm http://designdrumm.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php Karl DeSaulniers Design Drumm http://designdrumm.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php Karl DeSaulniers Design Drumm http://designdrumm.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php Karl DeSaulniers Design Drumm http://designdrumm.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

No, no, you missed my meaning... I don't care about line ending... I care about trailing whitespace on non-empty lines. modified one that 'cleans' the new lines: preg_replace( /((\r|)\n(\h*|))+/im, PHP_EOL , $input ); Yes, this is preferred with respect to line ending IMHO. But it still strips trailing whitesapce. Almost there... but you've also got that first blank line still hanging around which is supposed to be removed :D lol ahh hell yeah; trim() it ;) I'm done for the night *rofl* Have a good night :D Cheers, Rob. -- E-Mail Disclaimer: Information contained in this message and any attached documents is considered confidential and legally protected.
