How to enter new line to html with Powershell - html

Question

I have a PowerShell script that opens an IE browser and fill a form.
I also have an csv file with phone numbers. how can I insert each phone number to new line on the value tag?
tried already:
$phoneBox = $IE.Document.getElementById($phonesID)
$phones = Get-Content -Path "c:\phones.csv"
foreach($p in $phones)
{
$phoneBox.value += "<br>" + $p + "<\br>"
}
and also:
$phoneBox = $IE.Document.getElementById($phoneID)
$phones = Get-Content -Path "c:\phones.csv"
foreach($p in $phones)
{
$phoneBox.value += $p + "\n"
}
and also:
$phoneBox = $IE.Document.getElementById($phoneID)
$phones = Get-Content -Path "c:\phones.csv"
foreach($p in $phones)
{
$phoneBox.value += $p + "
" + "
"
}
EDIT:
The Html element I AM REFERING TO IS:
<textarea name="ctl00$MainContent$reciSel$TabsContacts$tabFromFile$txtFromFile" tabIndex="0" id="ctl00_MainContent_reciSel_TabsContacts_tabFromFile_txtFromFile" style="width: 98%; height: 386px; overflow-x: hidden;" onkeyup="PhoneNumbersTxt_onChange(this.value);" onkeypress="AddNewLine(this,event);" rows="2" cols="20" wrap="off" autocomplete="off">Here I need to enter each number to new line</textarea>

Literal whitespace is not parsed as formatting information in HTML (all consecutive whitespace is collapsed to a single space in the output).
Either put each phone number in a separate paragraph
$phoneBox.value += '<p>' + $p + '</p>'
or (if you want it in a single block element with a linebreak after each entry) put a single <br> (or <br/> if you want valid XHTML) after the number:
$phoneBox.value += $p + '<br>'
That does not apply to the content of textareas, though. For those you add linebreaks like this (LF only):
$phoneBox.value += $p + "`n"
or like this (CR-LF):
$phoneBox.value += $p + "`r`n"
PowerShell escape sequences start with a backtick, not a backslash.
