Description: This article is the third in a series of articles on manipulating XML data with ASP. Before proceding with this article, I recommend that you read Saving HTML Form Data to XML and Editing XML with XSL and ASP.The example in this article is very similar to the example on Saving HTML Form Data to XML. However, instead of creating a new file each time that the form is submitted, we will check to see if the file already exists, and if it does, we will append to it. Using this type of technique, we are creating a data construct similar to a data base table.
