In an .html file, I would like to replace this string of text:

<script type="text/javascript">$(document).ready(function () {$('.enhancedhtml-dynamic-table').dataTable();} );</script>

Open in new window

With this:

$(document).ready(function() {
        "aLengthMenu": [[25, 50, 75, -1], [25, 50, 75, "All"]],
        "iDisplayLength": 25
} );

Open in new window

How can I add these instructions within an existing Powershell script?

Current I use this method in Powershell but it is not working:

$oldcontent = '... first string here'
$newcontent = '... second string of text here'
$writeto = '.\Report.html'

((Get-Content -path $writeto -Raw) -replace $oldcontent,$newcontent) | Set-Content -Path $writeto

Open in new window

Thanks in advance for your assistance.
