How to write to an XML file
Writing to XML files is quite easy in ASP.NET as there are so many objects prepared for you -- you just need the syntax on how to use them. This code shows you how to write a simple member XML file.
<%@Page Language="VB" Debug="True" %>
<%@Import Namespace="System.XML" %>
<%@ Import Namespace="System.IO" %>
<script language="vb" runat="server">
Sub Page_Load()
Dim strCurrentPath As String = Request.PhysicalPath
Dim strXMLPath As String = Left(strCurrentPath, InStrRev(strCurrentPath,
"\")) & "members3.xml"
Dim objXMLWriter As XmlTextWriter
Try
objXMLWriter = New XmlTextWriter(strXMLPath, Nothing)
outDocURL.innerHTML = "Writing to file: <b>"
& strXMLPath & "</b>"
Catch objError As Exception
outError.innerHTML = "<b>* Error while accessing
document</b>.<br />" & objError.Message & "<br />" & objError.Source
Exit Sub
End Try
objXMLWriter.Formatting = Formatting.Indented
objXMLWriter.Indentation = 3
objXMLWriter.WriteStartDocument()
objXMLWriter.WriteComment("Created on " & Now())
objXMLWriter.WriteStartElement("members")
objXMLWriter.WriteStartElement("member")
objXMLWriter.WriteAttributeString("position", "regular")
Dim intYears As Integer = 4
objXMLWriter.WriteAttributeString("years", intYears.ToString("G"))
objXMLWriter.WriteElementString("Address", "2374 Ash St.")
Dim datBirthday As DateTime = #03/05/2000#
objXMLWriter.WriteElementString("birthday", datBirthday.ToString("yyyy-MM-dd"))
Dim intContributions As Integer = 23443
objXMLWriter.WriteElementString("contributions", intContributions.ToString("G"))
Dim blnLocal As Boolean = True
objXMLWriter.WriteElementString("local", blnLocal.ToString())
objXMLWriter.WriteEndElement()
objXMLWriter.WriteEndElement()
objXMLWriter.Flush()
objXMLWriter.Close()
Dim strXMLResult As String
Dim objSR As StreamReader = File.OpenText(strXMLPath)
strXMLResult = objSR.ReadToEnd()
objSR.Close
objSR = Nothing
outResults.innerHTML = "<pre>" & Server.HtmlEncode(strXMLResult)
& "<pre>"
End Sub
</script>
