我能够通过第二个链接从网站上读取动态信息(在下面的代码中进行了注释)。如果我取消注释第二行,则可以正常工作,并且可以获得所需的信息。如果我使用第一个链接,它将无法正常工作;生成的文件为0字节。
第一次,您可能必须按一些按钮,然后再次运行脚本(取决于浏览器)。那么如何获得理想的结果呢?我需要最上面的ETA:Arrival">ETA</a> : March 23, 2019 </td></tr> </table>

_RSSGetInfo()

; Url to get the source from.
$sUrl = 'http://wcf.mscgva.ch/publicasmx/Tracking.asmx/GetRSSTrackingByContainerNumber?ContainerNumber=MSCU4727397'
; Read source from the url.
$sSource = InetRead($sUrl)
; Convert source to utf-8 string (8 = utf-8).
$sSource = BinaryToString($sSource, 8)
; Get the eta dates (3 = return array of global matches).
$aETA = StringRegExp($sSource, '(?is)title="Estimated Time of Arrival">ETA</a>\s*:\s*(.*?)\s*<', 3)
; Display the eta date.
If UBound($aETA) Then
MsgBox(0, @ScriptName, $aETA[0])
EndIf
这使用正则表达式从RSS / XML源中的HTML获取ETA日期。
StringRegExp选项(?is)
是i
代表敏感,s
代表单行。
日期值周围可能存在一些空格,\s*
用于匹配它们。
:
是日期值的一部分,并且已匹配。
这使(.*?)
组可以仅获取预计到达时间。
$aETA
包含数组中的所有ETA日期,尽管第一个是$aETA[0]
Msgbox中显示的日期,这是您提到的预计到达时间
是评论顶部的那个。
