Regex problem , need immediate help


Recommended Posts

hi..

i am working on a script which extracts a webpage source and gets the table elements..

but my regex isn't working properly..

i want to extract the content between <table and </table> from the source..

code:

$file = FileOpen("tyu.txt")
$file_content = FileRead($file)
FileClose($file)
$table = StringRegExp($file_content, "(?s)<table((?s).*?)</table>",3)
_ArrayDisplay($table)

and this is the text file : http://www.comfaca.com/aiyo.txt

but the regex is working perfectly with the StringRegExpGui udf..

Thanks in Advance.

You want to extract proxies from hidemyass using regular expression? I've tried that, you're not going to get very far.

If that is what you want to do, this gets incredibly difficult and if you can't manage to simply extract a table from html, I don't see you anywhere in the near future succeeding with this. If it's not the proxies you're after, I couldn't imagine why you would want to extract the proxy table from their website.

Also, there are far simpler ways to make a successful "scrapper". Hidemyass looks pretty but it doesn't have all the proxies.

P.S. They implement about 7 or 8 different obfuscation methods to show their proxies, they do this because they obviously don't like scrappers taking their stuff, so on the user side, the proxies show up looking nice, but the html code is a gigantic confusing maze of html and CSS trickery that only render the right numbers and it's 10^100x simpler to just do it another way. This question is more suitable for a place like hackforums.net. They have working backdoored scrappers everywhere.

Nevermind, I guess when I tried before, it was when I knew less AutoIt a few months ago, this seems to work.

Thanks for your reply,

i have already succeeded in deobfuscating it.. i dont understand why you said i should post this question in some hackforum when my question is related to autoit regex..

it would be of much help if anyone could provide me with a solution to this regex problem

Whatever regular expression that can be used in AutoIt can be used in most other languages.

i have already succeeded in deobfuscating it..

I think you misunderstood me. But anyway, what the heck...

it would be of much help if anyone could provide me with a solution to this regex problem

$table = StringRegExp("<table HURRR DURRRF x3>YAY :D</table>", "(?s)(?i)<table(?i:[^>].*|)>(.*?)</table>",3)
ConsoleWrite($table[0] & @CR)

b47chguru,

Here is what you are asking for, although it is unlikely that it is what you want.

(?m)<table[.sS]*</table

note: rookie with regexp

kylomas

edit: Opps forgot to add grouping try this pattern

(?m)(?:<table)([.sS]*)(?:</table)

hmm, I guess I should have tried it on the file first.

I wondering though

<td class="
jbjnbjnbjnbj

Mines only returning that, but why? It "looks" like it should have worked.. :sweating:

@Fluttershy - maybe because you are not in multiline mode, don't now for sure, got a headache from thinking about regexp for 2 mins

kylomas

@b47chguru - don't assume 1 match, iterate through the results array.

edit: not true s includes the EOL chars

b47chguru,

Define "still does'nt work". I copied your file to a regexp tester and it worked fine. Are you sure that you saw my update, the 1st pattern was incorrect.

@kylomas

sorry, my bad... my first regex itself was working, the problem is that _arraydisplay doesnt display it

anyways thanks for helping out! :)

yeah, you're right, but you should be using "(?s)<table(.*?)</table>", since you already defined (?s) once, you don't have to do it again fyi. lol, wow, I just did some testing, no, this is not correct.

Also, you're trying to extract the proxies am I correct? Why not use tbody instead of table?

b47chguru,

Sure about that? Why would _arraydisplay not display an array, given that the regexp returned one. You can interrogate @error following a regexp call to make sure of the result.

Flag = 3 or 4 :

@Error Meaning 0 Array is valid. 1 Array is invalid. No matches. 2 Bad pattern, array is invalid. @Extended = offset of error in pattern.

yes, _arrayDisplay function doesnt display the array element in this case $table[0]

Ok, I wanted to test my self for some reason and felt an urge to do it. Especially after asking you how you did it to deobfuscate your stuff and repliad by saying you'd post it sometime in the exmples script, people who usually do this rarely actually do.

So here it is, this will recover every single proxy by parsing the html and css.

OMG THIS SITE!

It stopped working already :P

very easy to fix though, I'll let anyone who's interested figure it out.
