I was able to read dynamic information from a website through the second link (commented out in the code below). If I uncomment the second line it works fine, and I get the information I want. If I use the first link it doesn't work; the file that gets generated is 0 bytes.

The first time you might have to press some button and run the script again (depends on browser). So how to get the desired result? I need the ETA, the one at the top: Arrival">ETA</a> : March 23, 2019 </td></tr> </table>.

_RSSGetInfo() didn't work either (the shipper indicates it is an XML RSS feed, but I don't know whether this is the right thing to use; it gave me a blank).

#include <MsgBoxConstants.au3>
#include <IE.au3>
#include <Array.au3>
#include <Date.au3>
#include <String.au3>
#include <Excel.au3>
#include <WinAPIFiles.au3>

$Link = "http://wcf.mscgva.ch/publicasmx/Tracking.asmx/GetRSSTrackingByContainerNumber?ContainerNumber=MSCU4727397"
;$Link = "https://www.hapag-lloyd.com/en/online-business/tracing/tracing-by-booking.html?blno=HLCUEUR1810BCLY1"

$file = fileopen(@ScriptDir & "XYZ.txt", 2 + 8)
$IE = _IECreate($Link, 0, 1, 1, 1)

Sleep(2000)
$source = _IEDocReadHTML($IE)
FileWrite($file, $source)

MsgBox(0, "Source", $source)

Here is the RSSInfo version, which gives me a blank (I found this on the internet, and edited it) :

EndIf

This gets the ETA date from the HTML within the RSS/XML source usings regular expressions.

StringRegExp options (?is) are i for insenstive and s for single line.
Some spaces may exist around the date value, s* is used to match them.
The : is part of the date value and is matched.
This allows (.*?) group to get just the ETA date.

$aETA contains all ETA dates in an array, though the 1st is $aETA[0]
which is shown in the Msgbox, This is the ETA date you mentioned
is the one at the top in a comment.

Example listing <description> -tags (using XML.au3), extracting from contained HTML (using IE.au3) :
