IE.au3 getting an element via XPath

[Kelle 0]

Hello guys,

I've found a nice function that "simulates" the XPath Functionality from Firefox. See below.

I try to get the "register"-Link from yahoo.com.

Even if I try to get the 3rd Main Div of the page, I notice that it doesn't work.

I tried this:

$oIE = _IECreate("http://de.yahoo.com", 0, 1)
$test = $oIE.document.body.getElementsByTagName("div").item(3).outerHTML
MsgBox(64, "Test", $test)

But when I do this, I get the 3rd Div on the page which is included in the 1st main div.

How can I get the 3rd Main div to navigate to the "register"-Link ?

Hmm, nobody knows ?

[DaleHohm 61]

You need to provide a better explanation. I looked at the URL provided and I see no "register"-link.

If you visit "http://de.yahoo.com" you will see in the top right corner the link "Registrieren".

This one is what I need.

I prefer to get this link with the simulated XPath Function.

[DaleHohm 61]

I can show you how to get a reference to that link, but sorry, I have no desire to debug that function.

What reference can I get to this link ?

The only ones I know is _IELinkClickByIndex and _IELinkClickByText.

Is there are another, maybe better, one ?

[DaleHohm 61]

What are you trying to accomplish?

Here is one way to get a reference to your link:

#include <IE.au3>

$oIE = _IECreate("http://de.yahoo.com")
$oAs = _IETagnameGetCollection($oIE, "a")
For $oA in $oAs
    If StringInStr(_IEPropertyGet($oA, "innertext"), "Registrieren") Then ExitLoop
Next

; $oA is a reference to your link

Thank you that method is very good.

I try to accomplish to get one specific link.

For example: If there are two hyperlinks on the page with the same text, e.g. "Registrieren" and I want the first. Than there is only the possibility to get this link with _IELinkClickByIndex ... or ?
