Android Code Snippet Load data from Website and display in a WebView as a Marquee

I wanted to realize a kind of Ticker with some metal datas.

So i created a WebView, read in the data from a financial website, work them up and load the HTML in the WebViewTicker moving from right to left

.
The WebViewNews-Webview is for displaying in a big view,
The WebViewTicker-WebView is a small banner at the buttom of the screen:

So here is the code for this:

Sub LoadWebTickerei

    Dim http As HttpJob
    http.Initialize("", Me)
    http.Download("https://www.boerse.de/nachrichten/Goldpreis/XC0009655157")

    Wait For (http) JobDone(job As HttpJob)

    If job.Success Then
        Dim htmlContent As String = job.GetString
        'Log(htmlContent)
    End If
        
    Dim startIndex As Int = htmlContent.IndexOf("Uhr")-6
    ' Log(startIndex)
    Dim endIndex As Int = htmlContent.LastIndexOf("Uhr")+310
    ' Log(endIndex)
        
        
    'Die Enchilada entwursten...   
    Dim extractedHtml As String = htmlContent.SubString2(startIndex, endIndex)
     extractedHtml = extractedHtml.Replace("</div>","")
    extractedHtml = extractedHtml.Replace("<div class=<","")
    extractedHtml = extractedHtml.Replace("row row-bordered","")
    extractedHtml = extractedHtml.Replace("<div class=","")' extractedHtml
    extractedHtml = extractedHtml.Replace("col-xs-9 col-md-","")' extractedHtml
    extractedHtml = extractedHtml.Replace("col-xs-3 col-md-2","")' extractedHtml
    extractedHtml = extractedHtml.Replace(Chr(34) & Chr(34) & ">","")
    extractedHtml = extractedHtml.Replace(Chr(34) & "10" & Chr(34) & ">","")
    extractedHtml = extractedHtml.Replace(Chr(34) & Chr(34) & ">","")
'    Log(extractedHtml) 'visueller Check
    WebViewNews.LoadHtml(extractedHtml)
'    WebViewNews.Visible=True 'visueller Check
    WebViewTicker.LoadHtml("<marquee>" & "News zu Edelmetallen: " & extractedHtml & "<marquee>")

End Sub
