[phamtua]

Hi all, please help me get link of this tag name called "a"
 

<a href="https://video-lga3-1.xx.fbcdn.net/v/t42.9040-2/31722452_600373350325502_2471331569462149120_n.mp4?_nc_cat=0&amp;efg=eyJybHIiOjUyMiwicmxhIjo1MTIsInZlbmNvZGVfdGFnIjoic3ZlX3NkIn0%3D&amp;rl=522&amp;vabr=290&amp;oh=471bd4ed5bd1821ea21cbd1318be5aa9&amp;oe=5B236FDB" download="-fbdown.net.mp4"><strong style="font-size:19px;" class="text-primary">Download Video in Normal Quality</strong></a>

My code:
 

#include <IE.au3>
Local $oLinks = _IELinkGetCollection($oIE)
Local $iNumLinks = @extended

Local $sTxt = $iNumLinks & " links found" & @CRLF & @CRLF
For $oLink In $oLinks
    $sTxt &= $oLink.href & @CRLF
Next
MsgBox($MB_SYSTEMMODAL, "Link Info", $sTxt)

 I tried to use this code (below) but it show many links, I need to return this link:

So do you know the name of the url before hand?  What exactly are you trying to achieve?

This web support get link: https://www.fbdown.net/
After set value to the input and click Download button, I need to extract link

Sorry had errands to run, you can use something like:

#include <IE.au3>
Local $oIE = _IEAttach("https://www.fbdown.net/download.php", "url")
Local $oIETag = _IEGetObjById($oIE, "sd")
ConsoleWrite("URL = " & $oIETag.firstElementChild.href & @CRLF)
