I'm new to XML. I have a questionairre, the results of which, I can process through .ASP and display in an XML document like the following:<?xml version="1.0" ?> - <newdata>- <field id="T1" taborder="1"><field_value>mon, tue, wed</field_value> </field>- <field id="RadioGroup1" taborder="2"><field_value>bus</field_value> </field>- <field id="RadioGroup2" taborder="3"><field_value>spouse</field_value> </field>- <field id="RadioGroup3" taborder="4"><field_value>some</field_value> </field>- <field id="textfield" taborder="5"><field_value>arniemonday</field_value> </field>- <field id="submit" taborder="6"><field_value>Submit</field_value> </field>- <field id="name" taborder="7"><field_value>Arnold Palmer</field_value> </field></newdata>How do I stop the data from refreshing every time a new user submits their data? In other words I want the data to keep "stacking" until I am ready to import all of the responses into Excel. I've been to more forums and read more tutorials than you can imagine and just cannot get it! Thanks for your help.

This sounds like a design problem. You need to store the resulting data somewhere or it is lost on every new request. I would imagine your application has some kind of persistence mechanism where you can store the result of this query, and then on succeeding queries, append the new data to your existing data.If you dont store the results it will get wiped every time.There are many different kinds of scope that you can use, and picking the proper one and implementing it will accomplish your goal. For example if you have a web counter, and you want it to refresh per session visit, you can store the hit count in a session scoped variable. This means that when the user's session expires, the counter will be reset since the user's session data is not persisted. If you want the hit counter to store the hit count beyond the session scope, you'll have to store the hit count in something like a database, which can persist data beyond a session or a request. At the moment, your results get whiped out on every request because I am guessing your application is returning results within a request scope. I suggest using some kind of filter design pattern that intercepts your query and stores it somewhere for later retrieval, probably in a session variable.

Are you using the FileSystemObject to write your XML file?If so, you use the CreateTextFile method of the FileSystemObject and you can specify whether you overwrite previous data that is in the file or append the data to the contents of the file.The XML file will need to have a single root element - perhaps called "questionnaire" - that will contain all of your "newdata" elements. Perhaps it could look something like this:

<questionnaire><newdata></newdata><newdata></newdata><newdata></newdata></questionnaire>

Every time you need to write new data to the file, you could read the file contents, delete the last line of the file (the "</questionnaire>" line), append the new data to the end of the file, and then append "</questionnaire>" back to the end. That way "</questionnaire>" will always be the last line of the data and each new "newdata" element will be appended just above that closing "questionnaire" tag.

I am using server.CreateObject to create the xml file. Here is the ASP script I am using to collect the data and output to XML:<%@LANGUAGE="VBSCRIPT" CODEPAGE="1252"%><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /><title>Untitled Document</title></head><body><%'--------------------------------------------------------------------'The "ConvertFormtoXML" Function accepts to parameters.'strXMLFilePath - The physical path where the XML file will be saved.'strFileName - The name of the XML file that will be saved.'--------------------------------------------------------------------Function ConvertFormtoXML(strXMLFilePath, strFileName) 'Declare local variables.

I think you need to change the way you are organizing the data in the XML file. Your current root node is "newdata" and you are storing the answers to the questions in "field" elements. What you are lacking here is a way to differentiate one user's data from another user's data.Either change your XML so that it is something like:

<questionnaire><newdata id="cust1">  <field /></newdata><newdata id="cust2">  <field /></newdata></questionnaire>

or:

<newdata><userdata id="cust1">  <field /></userdata><userdata id="cust2">  <field /></userdata></newdata>

Now, I don't know much about using server.CreateObject to create an XML file so I can't provide any code, but it sounds like you're going to have to read the contents of the XML file before you convert the inputs from the form into XML. Then you'll need to append the XML that is generated from the inputs to what is already loaded in your XML object. Once that is done, you can write the data to back to the file. Otherwise, you'll continue to overwrite the previous user's data.

The information from 5,000 to 50,000 customers will be entered into that form between the times that you are able to import the data into your Excel spreadsheet? Is there a reason you aren't using a database like MySQL or SQL Server?
