WebPage parser

KarlosTHG · September 16, 2009

Hi again guys,

I study in the Universidad EAFIT in Colombia and this provide an user and password for a platform to get the results of the quiz and the works, Well, i need to make a script to download the page and parse it to fill a gui with the results, the second part is easy but i have not idea to download the page automatically because this request the authentication info. How i can do that?

Sorry for my english but i have only taken a few of classes.

Any help would be appreciated. thanks!

With the function:

InetGet

To use a username and password when connecting simply prefix the servername with "username:password@", e.g.

"http://myuser:mypassword@www.somesite.com"

searching in the code i found a interesting line:

with this explaination:

traslate:

Show the errors generated with the form validation

and i think that maybe is PHP or something like that

is there a way to know the syntax of the post request for login-submit.do

thanks

When you open a page in your browser, it is essentially downloaded to your machine and the browser gives you an interface to work with it. I am confused by your question. Once you download the page, how do you plan to work with it and what do you intend to do with the results?

KarlosTHG · September 16, 2009

I want to do a script that shows the schedule, the results of quiz and other info in my own way, like a offline platform, then i need to download the page which has login protection in some kind of PHP, parse it, save to hard disk, and show the information retrieved in my application GUI, I can do everything, but the page download

I hope explained me well

Thanks

jvanegmond · September 16, 2009

Ok, so you download the page but instead of the page you wanted you get a login page? You want to parse the login page or something and build a HTTP request based on that? I fail to see where this is going.

KarlosTHG · September 16, 2009

I don't need the login page i need a page after the login but when i use InetGet with the page that i need, i always get the login page source because i dont know how to pass my login info into the script to download the page that i need.

i think that i can not explain me better, jaja,

bye and thanks

jvanegmond · September 16, 2009

Read over DaleHolms reply again and pay attention closely.

What is happening when you try to download the page directly:

- The page you are trying to download is redirecting you to the login page (probably because you don't have some cookies set)

- InetGet knows it's being redirected, so it downloads the page it's being redirected to instead

- You're stuck with the login page. LoL.

So what you should do is:

- Try to download the page

- Be redirected to the login page

- Log in on the login page

- Check if log in was succesful

- Try to download the page

For this you'll need a better way of handling a website than just the InetGet function, because there are a lot of things involved: POST HTTP requests, cookies, redirection.

DaleHolm has written a very nice library for this. It uses Internet Explorers internal workings to be able to interact with a website. You can find about all these things in the AutoIt help file. The functions all start with _IE and they're very convenient.

I don't attend a university at all. I just do this stuff in my free time. Kthxbye.

DaleHohm · September 16, 2009

How much do you know about HTML and the Document Object Model (DOM)?

To login, see _IECreate, _IEFormGetObjByName, _IEFormElementGetObjByName, _IEFormElementSetValue, _IEFormImgClick,

To save the page, see _IEDocReadHTML or _IEBodyReadHTML

There are more refined ways of getting individual elements off the page, but the techniques require knowedge of the DOM.

This is how I log in to the google mail: so you log in, retrieve info you need & close browser.

to get that $o_signin=_IEGetObjByName($oIE,"signIn") use DEBUGBAR for internet explorer - google it.

#include <IE.au3>
$oIE =_IECreate("http://mail.google.com/mail/?hl=et&tab=wm");opens the webpage
; get pointers to the login form and username, password and signin fields
$o_login = _IEGetObjByName($oIE,"Email")
_IEFormElementSetValue ($o_login, "mudak.yo")
$o_password = _IEGetObjByName($oIE,"passwd")
_IEFormElementSetValue ($o_password, "dasitmeinpasswerthohoho")
$o_signin=_IEGetObjByName($oIE,"signIn")
_IEAction($o_signin,"click")

Sleep(5000)

_IEQuit($oIE)

And this is how I work with webpage source hope it helps:

#include <INet.au3>

$URL        = 'www.muwebpage.rt'
$SEARCH_FOR = ' Downloads and Information</title>'


    $HTMLSource = _INetGetSource($URL)

    $_Arrayline = StringSplit($HTMLSource, @LF) ; this is the Array $_Arrayline
;~  
        for $i = 1 to $_Arrayline[0] 
            If StringInStr($_Arrayline[$i],$SEARCH_FOR) Then  ; if string contains word time                    
                _sample($_Arrayline[$i])
                ExitLoop
            EndIf
        Next

Func _sample($STRING)
;~ #ce ----------------------------------------------------------------------------

    $split = StringSplit($STRING,' Downloads and Information</title>',1)    ; split line to get DL URL Middle & Right part [ URL SGFDG ]
                
    ConsoleWrite($split[1] & @CRLF) 
;~                  
    $split = StringSplit($split[2],'"',1)       ; 3 split $split[2] to get Final page URL [ URL ]   
;~                  
    $DL_Link = $split[1]
;~                  
;~  $split = StringSplit($DL_Link,"/",1)  ; Get Filename from link          
                    
;~  $Filename_Save_as = $split[7]
    
    Return $DL_Link
;~                  
EndFunc

@Manadar: Thats is exactly what i need. About the university, I study Business administration and i just do this stuff in my free time too because is funny for me, and exercise my brain jajaja.

@DaleHohm: I will try these functions later because i have to study now. About HTML i just know the basics and about DOM I just know its name, but maybe i will read something about it later.

@goldenix: I will try the debugbar and your example later, but in your example a IE window should be showed? because this is a little bad-looking for an application, can i use the WinSetState function to hide the window?

Thanks to all of you i cannot wait to try yours examples but i have to read now a document about the globalization and how this affects the internal economy

Bye, and thanks again for your help.

KarlosTHG · September 21, 2009

@goldenix: hi again, i tried your script and it works very good and hide the windows too, now i can do my project, so many thanks men, and thanks to all the others who helped me

KarlosTHG · September 22, 2009

Is there a way to download just the HTML without the images to get a fast download?
