Help with tags in COM

AllUrBaseRBelong2Us · 23 Nov 2015, 04:57

Hey there,
I'm writing a script to retrieve info from a tag which looks like this

<div class="some class name" style="background-image:insert random url here"></div>

I'm trying to extract style name/ backgroundimage URL.

So, is there any way to extract that info?

Just a FYI: I've tried storing the classnames in a var using getElementsbyClassName and looped through them but they don't show all the class names - the one I need isn't there. I've checked with Inspect Element in IE and can confirm that the specific class name DOES exist. That's why I'm trying to meddle with the style properties now.

Thanks in advance for your help.

You just have to parse the DOM for div elements

Code: Select all

html =
(
<html><head></head>
<body>
<div class="a class name">foo</div>
<div class="some class name" style="background-image:insert random url here">This is what I'm after</div>
<div class="another class name">bar</div>
</body></html>
)

document := ComObjCreate( "htmlfile" ), document.Write( html )

try While ( divObj := document.getElementsByTagName( "div" )[ a_index-1 ] )
{
    if ( divObj.className = "some class name" )
        Value := divObj.innerText
}

msgbox % Value

obviously change the objects etc back ie.document... and so on.

Sorry but I didn't get what you meant by that. Do I have to download the website's HTML code to a var and then proceed?

@TLM, thanks for being so helpful on IRC

The script runs brilliantly. I've found out where I was making a mistake
I wrote

Code: Select all

divObj.backgroundimage

instead of

Code: Select all

divObj.style.backgroundimage

Thanks a ton!

PS:You're the best! Have a great day
