Store HTML form data in XML format (2)

Once the document is archived, if you open the document again, it will appear as a list of the following code:

Myxmldoc.xml:

<?xml version= "1.0"?>
<rootElement>
<childelement1/>
<childelement2/>
</rootElement>

In the "Myxmldoc.xml" document, ChildElement1 and ChildElement2 appear in the form of an empty elements. If they are assigned, each value is enclosed by a tag.

Now, let's think about how to write HTML data into an XML document. We already know how to create and store XML documents. The process of writing a form data into an XML document has now evolved into the request Object "s" Form collection and the steps to set each form field's value book to XML element value are repeated. The above can be done through ASP.

Example: Transferring data to XML

Now, let's give an example of an ordinary HTML form. This form has user name, address, telephone, and e-mail and so on several domains. and write this information to the XML file and save it.

Entercontact.html:
<title>
Contact information
</title>
<body>
<form action= "processform.asp" method= "POST" >

Name: <input type= "text" id= "FirstName" name= "FirstName" ><br>
Last Name: <input type= "text" id= "LastName" name= "LastName" ><br>
Address #1: <input type= "text" id= "Address1" name= "Address1" ><br>
Address #2: <input type= "text" id= "Address2" name= "Address2" ><br>
Phone Number: <input type= "text" id= "phone" name= "Phone" ><br>
E-mail: <input type= "text" id= "email" name= "email" ><br>
<input type= "Submit" id= "Btnsub" name= "Btnsub" value= "Submit" ><br>
</form>
</body>

Send the data in form to the processform.asp ... This is an ASP page that will repeatedly call the same function to write form data to an XML file in this ASP.

Processform.asp:

<%
"--------------------------------------------------------------------
"The" Convertformtoxml "Function accepts to parameters.
"Strxmlfilepath-the physical path where the XML file would be saved.
"Strfilename-the name of the XML file that'll be saved.

Function Convertformtoxml (Strxmlfilepath, strFileName)
