Read XML file and replace placeholder with value using C# and VB.Net in ASP.Net

Hi bhadriau,

I have created sample code which full-fill your requirement.You need to modify as per your requirement.

HTML

<div>
    <asp:Literal ID="lblId" runat="server" />
</div>

XML

<?xml version="1.0" encoding="utf-8"  ?>
<left  requires="SenderFullName">{SenderFullName}</left>
<left requires="ReceiverFullName">{ReceiverFullName}</left>
<left requires="ReceiverCountry"> {ReceiverCountry}</left>
<left requires="AccountId">{AccountId}</left>

C#

private void PopulateData()
{
    string body = string.Empty;
    string breakline = "<br />";

    string SenderName = "Sender Name";
    string Receiver = "Receiver Name";
    string country = "Country";
    string AccountId = "A0001";        
        
    using (StreamReader reader = new StreamReader(Server.MapPath("~/XMLFile.xml")))
    {
        body = reader.ReadToEnd();
    }

    body = body.Replace("{SenderFullName}", !string.IsNullOrEmpty(SenderName) ? SenderName + breakline : "");
    body = body.Replace("{ReceiverFullName}", !string.IsNullOrEmpty(Receiver) ? Receiver + breakline : "");
    body = body.Replace("{ReceiverCountry}", !string.IsNullOrEmpty(country) ? country + breakline : "");
    body = body.Replace("{AccountId}", !string.IsNullOrEmpty(AccountId) ? AccountId + breakline : "");
    this.lblId.Text = body;
}

Vb.Net

Private Sub PopulateData()
    Dim body As String = String.Empty
    Dim breakline As String = "<br />"

    Dim SenderName As String = "Sender Name"
    Dim Receiver As String = "Receiver Name"
    Dim country As String = "Country"
    Dim AccountId As String = "A0001"

    Using reader As New StreamReader(Server.MapPath("~/XMLFile.xml"))
        body = reader.ReadToEnd()
    End Using

    body = body.Replace("{SenderFullName}", If(Not String.IsNullOrEmpty(SenderName), SenderName & breakline, ""))
    body = body.Replace("{ReceiverFullName}", If(Not String.IsNullOrEmpty(Receiver), Receiver & breakline, ""))
    body = body.Replace("{ReceiverCountry}", If(Not String.IsNullOrEmpty(country), country & breakline, ""))
    body = body.Replace("{AccountId}", If(Not String.IsNullOrEmpty(AccountId), AccountId & breakline, ""))
    Me.lblId.Text = body
End Sub
