[Problem]Cutting Divs from Source code String read from saved HTML page.

Recommended Posts

Mikeman27294

Hey everyone,

I am working on a script for which I have a webpage saved. At the start of the program, the program loads the source code into a variable, removes all script and noscript, and then it must cut out a div called product (<div id="product">). The problem is that each time I try to write this function, I have problems detecting how many child divs it has nested in it. I have tried also writing a function that determines the amount of characters in the div, for trimming to the right of the div, but this has not worked. I dont wish to use an embedded browser for my program, I just want to work with the strings. Could anybody give me any pointers?

Thanks.

EDIT

I have found the following forum post:

The problem is though, that (as far as I am aware) it requires you to use the embedded browser or just use internet explorer, which will not help me as I just want to read the source code. I am aware that I can load the source into the browser and then hide the browser, but I would rather just "cut" the div out of the source.

Thanks.

SOLUTION

Thanks to thanlankon. Please note that this also returns the div tags (opening and closing) for the specified div. It also removes the " character from either side of the ID name.

_HTMLGetDIVCode('html code here', 'id of div here')
Func _HTMLGetDIVCode($html_code, $div_id)
    Local $o_htmlfile = ObjCreate('HTMLFILE')
    If Not IsObj($o_htmlfile) Then Return SetError(-1, 0, '')
    $o_htmlfile.open()
    $o_htmlfile.write($html_code)
    $o_htmlfile.close()
    Local $div = $o_htmlfile.getElementByID($div_id)
    If Not IsObj($div) Then Return SetError(0, 0, '')
    Return $div.outerHTML
EndFunc

Please show the text before and after the cutting. That way it should be easy to have a look.

Ok, I will attach 2 HTML documents.

Before

After

If anybody is in query about whether these files contain viruses or not, then I can email them to you (They are just 2 HTML files called File and Result, respectively). It would also be appreciated if anybody who downloads them could verify that they are virus free (Just to clear the doubts), and thanks to anybody who does.

This is what I was hoping to achieve from the program. I wish to remove the div named product, and write that to a file. I already have my program removing script and noscript, which is also demonstrated in the result file.

If you want to view the original page, it was saved from here:

Sorry, I thought you would still be able to download them. I will fix that.

EDIT

Ok, I fixed that. Thankyou for letting me know.

How do you determine it manually? All I can see is starting at id="product and end at

</div>

</div>

</div>

</div>

Everything between ist what you extracted.

I found an object called HTMLFile, like Shell.Explorer.2 (use in _IECreateEmbedded), but the object HTMLFile just work with source code, not display anything like Shell.Explorer.2

How about the code below, Mikeman:

_HTMLGetDIVCode('html code here', 'id of div here')

Func _HTMLGetDIVCode($html_code, $div_id)
    Local $o_htmlfile = ObjCreate('HTMLFILE')

    If Not IsObj($o_htmlfile) Then Return SetError(-1, 0, '')

    $o_htmlfile.open()
    $o_htmlfile.write($html_code)
    $o_htmlfile.close()

    Local $div = $o_htmlfile.getElementByID($div_id)

    If Not IsObj($div) Then Return SetError(0, 0, '')

    Return $div.outerHTML
EndFunc

thanlankon,

Did you find any MS doc for "HTMLfile"?

I had a VBS routine using the IE parsing engine and this object to extract just what the OP is looking for, however, I have not been able to successfully translate it to AutoIT...finally gave up and used SRE for parsing.

Everything between ist what you extracted.

What I was doing is that I had a do while loop, and a variable which incremented each time a div tag was detected, and the opposite when the close div tag. This would return the amount of lines (the starting line is known), and I could then read each line and write it to the file, but this just returned 0 :S

I found an object called HTMLFile, like Shell.Explorer.2 (use in _IECreateEmbedded), but the object HTMLFile just work with source code, not display anything like Shell.Explorer.2

    $o_htmlfile.open()
    $o_htmlfile.write($html_code)
    $o_htmlfile.close()

    Local $div = $o_htmlfile.getElementByID($div_id)

    If Not IsObj($div) Then Return SetError(0, 0, '')

    Return $div.outerHTML
EndFunc

That looks good. I will place it in my code and see how well it works, thanks :D Edited by Mikeman27294

Yep, that code works. I will paste it in a spoiler in my first post for future reference, thankyou, thanlankon.

actually no, kylomas. the methods and properties of HTMLFILE like object "document" in javascript, I think so.(of course they have some differences but I'm not sure about them.) I don't know much about VBS but can you post your VBS code here? maybe I can help you to translate them.

not at all, Mikeman

Ok, so I was using that code, and it was working quite well, until I found that it was stripping the " characters from div IDs. Are there any work-arounds for that? I dont understand what the problem is with it but I know that before it enters that function, the " characters are there and they arent when the string leaves it :S

I'm not entirely sure what data you are after. I suggest mapping the opening and closing tag positions using StringInStr with the occurence parameter. Then you can grab whatever characters you wish between any two tags. Things like this can also be done using regular expressions.

Basically, I want to go onto an online webstore, and get data about the product being sold.

I have tried using string in str but that didnt work properly (Not a clue why, I use that function all the time :S). I also dont know how to do RegEx really, so for the time being, I will just stay away from it till I have a bit of free time to learn it.

Here's a simple way to get starting positions of the opening divs. The code is just an example of how you might go about solving this problem. To make it work you will have to make some modifications. I hope it gives you some ideas.

Local $html = "<div><div><div>Hello World</div></div></div>"

Local $iDivCount = 1, $sDelimStr = ""
While StringInStr ( $html, "<div" , 0 , $iDivCount)
    $sDelimStr &= StringInStr( $html, "<div" , 0 , $iDivCount) & ","
    $iDivCount += 1
WEnd
MsgBox(0, "Staring positions", StringTrimRight($sDelimStr, 1))

Earlier, the one I tried to have a go at basically read each line individually, and if '<div' was in it, it would increment a variable. then if it found '</div>', it would do the opposite.

What I would really need is the beginning, and the ends of each one.

I might have another crack at it soon.

I don't see any other way than adding and subtracting increments. But my suggestion is to simplify the process by first just looking for the positions of the tags. Once you know this you can sort them in order and select between them more easily.

Something like this might work if you're after the specific info.

Add your own divs afterwards if you need them.

Local $url = 'http://www.oo.com.au/Prima_72_Bottle_Wine_Cooler_-__P4022.cfm'
Local $htm = BinaryToString(InetRead($url, 1))
;
Local $s = ''
$s &= GetPageInfo($htm, 'inner">' & @CRLF & '<h1>', '</h1>') & @CRLF
$s &= 'Price: ' & GetPageInfo($htm, 'Price: <strong>', '</strong>') & @CRLF
$s &= GetPageInfo($htm, 'rrp"><strong>', '</strong>') & @CRLF
MsgBox(0, '', $s)
;
Exit
;
Func GetPageInfo($htm, $tag1, $tag2)
    Local $a = StringRegExp($htm, '(?i)(?s)' & $tag1 & '(.*?)' & $tag2, 3)
    If IsArray($a) Then Return $a[0]
EndFunc

Because my code use HTMLFILE, the object HTMLFILE automatically remove the " character that wraps value of some properties of the tag like ID. but I wonder what the problem with it is. Although the " character is removed but you can parse the code normally. I think it does not matter much.

      Is there a way to grab non-hardcoded but rather javascript generated data from a webpage?
      Tried a get request as well as _IEBodyReadHTML but both seem to grab the code without the javascript generated data.
      $oHTTP = ObjCreate("winhttp.winhttprequest.5.1") $oHTTP.Open("GET", "link", False) $oHTTP.Send() $oReceived = $oHTTP.ResponseText $oStatusCode = $oHTTP.Status Global $DataArray[10][5] If $oStatusCode <> 200 Then Exit MsgBox(1, "Error", "Status Code <> 200") EndIf FileWrite(@ScriptDir & "\output.txt", $oReceived) ; //////// #include <IE.au3> Local $FullLink = "link" Local $oIE = _IECreate($FullLink, 0, 0) _IELoadWait($oIE) Local $sText = _IEBodyReadHTML($oIE) FileWrite(@ScriptDir & "\output.txt", $sText)

      Hello Members of this best Forum
      i have a question please
      for example if i have a long string
      and i want to extract a text between two tag
      what i can do to make that?
      note :
      i know that there is a
      StringRegExp function
      it's do that work
      but it result is be as an array
      i want the result to be a string
      is there any function on autoit can do that?
      Thanks in advance.

      Hello!
       
      I wrote myself a script to follow Google Maps Polyline encoding steps: https://developers.google.com/maps/documentation/utilities/polylinealgorithm, and that works (although I think that it's a bit janky), but now I'm having issues getting the output.
       
      When I run the script, all the points come out correctly in the console, and even when they're the only things that I log, it displays them fine. However, I'm adding each point into a variable to return all of them at once at the end, fully formatted, and it's only taking the very first point. I can't figure out what I'm doing wrong, as it seems fine.
       
      When run with the default value, it should output this at the end: Custom Polygon: _p~iF~ps|U_ulLnnqC_mqNvxq`@
      But instead I'm just getting this: Custom Polygon: _p~iF
       
      I know that it's reaching the string combination lines because it's logging the data before it (and even if a put log AFTER the $sPolygon &= $aPoints[0], it's logged fine).
       
      Here's my full code (problem is lines ~209 - 234, search "$sPolygon &= $aPoints[1]"):

      I've tried:
      $sPolygon &= $aPoints[0] & $aPoints[1] ;---- $sPolygon = $sPolygon & $aPoints[0] & $aPoints[1] ;---- $sPolygon = $sPolygon & String($aPoints[0] & $aPoints[1]) ;---- $sPolygon = String($sPolygon) & String($aPoints[0]) & String($aPoints[1]) ;---- $sPolygon &= $aPoints[1] $sPolygon &= $aPoints[0] ;----  
      I'm sure it's something basic that I'm overlooking, but I don't understand why it's not combining the strings. 
      Also, unrelated, why doesn't $LogFile = FileOpen($File, 9) create the directory/ file if they don't exist? 9 should be $FO_CREATEPATH (8) + $FO_APPEND (1)?
      Thanks!

      Hi!
      I want to get the signal in this website:
      https://binary-signal.com/pt/chart/eurusd
      I have tried using _IEBodyReadText  and some _StringBetween. What happens is that the text are being update every tick and _IEBodyReadText doesn't.
      To perform the update I used  _IEAction($oIE, "refresh") but it's not good because the website block me after some time due too many requests..
      Is there any other way to get this text every tick?
      PS: The text I want to get is WAIT, CALL or PUT.
       
      Here is the code:
      global $oIE = _IECreate ('https://binary-signal.com/pt/chart/eurusd', 0, 1 , 1 , 0) Local $sText = _IEBodyReadText($oIE) $result = _StringBetween ( $sText , 'PUTEUR/USD on Binary-signal.com', 'sinal está PRONTA') ;MsgBox ( 0, "asf", $result[0]) $espera=StringInStr($result[0], "WAIT") $compra=StringInStr($result[0], "CALL") $venda=StringInStr($result[0], "PUT") ;MsgBox($MB_SYSTEMMODAL, "", $espera) $n=0 $c=0 Captar() Func Captar() ;_IENavigate($oIE, "https://binary-signal.com/pt/chart/eurusd") ;MsgBox($MB_SYSTEMMODAL, "", $n) Local $sText = _IEBodyReadText($oIE) $result = _StringBetween ( $sText , 'PUTEUR/USD on Binary-signal.com', 'sinal está PRONTA') If (Not $compra=0) And $n=0 Then MsgBox($MB_SYSTEMMODAL, "", "COMPRE") $n=1 $c=$c+1 ;_IEAction($oIE, "refresh") Sleep(60000) Captar() ElseIf (Not $venda=0) And $n=0 Then MsgBox($MB_SYSTEMMODAL, "", "VENDA") $c=$c+1 $n=1 ;_IEAction($oIE, "refresh") ;MsgBox($MB_SYSTEMMODAL, "", $n) Sleep(60000) Captar() ElseIf (Not $venda=0) And $n=1 Then ;MsgBox($MB_SYSTEMMODAL, "", "Esperando próxima rodada") $n=1 ;MsgBox($MB_SYSTEMMODAL, "", $n) ;_IEAction($oIE, "refresh") Sleep(60000) Captar() ElseIf (Not $venda=0) And $n=1 Then ;MsgBox($MB_SYSTEMMODAL, "", "Esperando próxima rodada") $n=1 ;MsgBox($MB_SYSTEMMODAL, "", $n) ;_IEAction($oIE, "refresh") Sleep(60000) Captar() Else ;MsgBox("", "", "ESPERE") $n=0 Sleep(1000) ;_IEAction($oIE, "refresh") Local $sText = _IEBodyReadText($oIE) $result = _StringBetween ( $sText , 'PUTEUR/USD on Binary-signal.com', 'sinal está PRONTA') Captar() EndIf EndFunc

      This is another take on string triggers, triggers on specific strings.
      Able to simple text pasting,
      opening links (as long as there's a www. http:\\ or https:\\ at the beggining)
      and is able to open applications.
      The user selects the modifier key, and then uses a combination of that key with a couple others to perform tasks like
      screenshot the active window, (modkey + prtscr), turn off the screen (modkey + pause / break),
      open clipboard string in registry (modkey + R), change system volume (modkey + arrouw up/dn).
      The following keys pressed at the same time prompt for shutdown: S+D+T
      The following keys pressed at the same time prompt for restart: S+R+T
      Middle mouse button click on titlebar minimizes to tray, or a left mouse button click in the icon in the tray also minimizes.
      Trigger is set off by space or enter, and timeouts after 3 seconds.
      Shows your external, lan, and gateway ip's, can refresh with right mouse click, and opens the default browser if the correspondent button is pressed.
      Able to change system volume by a set percentage, reading from the inputbox the number the user sets, if 0 or empty uses system default.
      I made this because the existing string trigger applications didn't do it for me for a number of reasons.
      I did this for me, but if someone finds it useful all the better.
