Hi,
using HTML/javascript, a form has been created. now the user makes
selections using the form. i want to create a XML file that encapsulates
the user selections ie this XML file should contain the selections made
by the user. this XML file should also automatically change whenever the
user makes new selections on the HTML form.
a part of the HTML form is given below:
<form name="theForm">
<select name="sel" onchange="loadFile();">
<option> Choose the map u prefer
<option value="C:\My Documents\usa.jpg" height=50 width=20>US
<option value="C:\My Documents\uk.jpg" height=50 width=20>UK
<option value="C:\My Documents\spain.jpg" height=50 width=20>Spain
<option value="C:\My Documents\greece.jpg" height=50 width=20>Greece
</select>
</form>
now as soon as the user selects say,"US" from the options,
immediately the XML file should contain this selection. this XML file is
then sent to the server where a server side program extracts data from
the XML and does necessary processing.
my part is developing this dynamic XML. i have gone through some
tutorials but was unsuccesful. i want to know exactly how to use
JSP/Servlet to create the dynamic XML.
i just have no idea of how to start. if anybody can help me out by
starting the code development, i will continue it and develop the code.
this code is to have been developed by another person who has left
the project midway and now i am burdened with developing this code. i
have no time to read tutorials. so i request u to give me a pseudo-code
in JSP/servlet to generate this dynamic XML and i will proceed.
thanks in advance and eagerly looking forward to ur reply.

what is the format of your XML File. I mean what tags are you using to capture this selection?

Hi,
this is how i plan to write my XM file:
<?xml version="1.0" encoding="ISO-8859-1"?>
<userselection>
<fig id="1">C:\My Documents\usa.jpg</fig>
<fig id="2">C:\My Documents\uk.jpg</fig>
<fig id="3">C:\My Documents\spain.jpg</fig>
<fig id="4">C:\My Documents\greece.jpg</fig>
</userselection>
from the above XML file, using JSP/Servlet, i need to generate a dynamic XML file that captures only the selections made by the user.
is the above procedure right?

Use DOM(Document Object Model) or JDOM for this purpose. When the user selects something call a method which will write XML using DOM or JDOM.
