What is a fast way to get specific html objects?


Recommended Posts

I finished making a script to get element object information from various table columns with _INetGetSource and _StringBetween and StringRegExp. I put timers around my script and found out that _INetGetSource is the source of the slow downs. Could using IE udf be a lot leaner and faster?  Are there other ways that might be faster?

 

Edit: After some more forum searching and testing with IE.au3 library, I found that _IEBodyReadHTML and _IEDocReadHTML doesn't work unless you literally have an IE window open and loaded with the URL you want. I feel like that would take longer than _INetGetSource. I did read the difference between the 3 functions on another thread where Dale posted his explanation. Am I right about _IEBodyReadHTML and _IEDocReadHTML ? That it doesn't retrieve the sources unless you literally have an IE window open?

Could using IE udf be a lot leaner and faster?

No - it would be much slower. InetRead (which is used by _InetGetSource) retrieve only the source html-code of the requested page and leave it as is. The IE instead reads the source and look for additional content like images, css-files, javascript-files etc. and also loads this content. After that it renders all the stuff. So it has a lot more to load and work and so it can't be faster than a simple InetRead for getting the source code.

For demonstration a small speed comparison:

#include <IE.au3>

Global Const $N = 5
Global Const $s_URL = "https://www.whitehouse.gov/"


#Region get source code with InetRead
$iT = TimerInit()
For $i = 1 To $N
    $s_Source = BinaryToString(InetRead($s_URL, 1))
Next
$iT = TimerDiff($iT)
ConsoleWrite(StringFormat("% 20s: %8.3f ms\n", "InetRead", $iT / $N))
#EndRegion

#Region get source-code with IE
Global $oIE = _IECreate("about:blank", 0, 0, 0, 0)
$iT = TimerInit()
For $i = 1 To $N
    _IENavigate($oIE, $s_URL)
    $s_Source = _IEDocReadHTML($oIE)
Next
$iT = TimerDiff($iT)
ConsoleWrite(StringFormat("% 20s: %8.3f ms\n", "IE", $iT / $N))
_IEQuit($oIE)
#EndRegion

I like the way you use StringFormat. :)

Getting more speed

1. Get a faster internet connection

2. Switch to a compiled language

3. Cut out all the layers of frameworks and go to barebone HTTP protocol
   http://odetocode.com/Articles/741.aspx

I assume INetGetsource is still based on com object winhttp services 

https://msdn.microsoft.com/en-us/library/windows/desktop/aa384109(v=vs.85).aspx

    Const $sURL = "https://www.whitehouse.gov/"
    $oWinHttp = ObjCreate("WinHttp.WinHttpRequest.5.1")
    $oWinHttp.Open("GET", $sURL, false)
    $oWinHttp.Send()
    consolewrtie($oWinHttp.ResponseText)

It looks like another interesting article to read.
