RE: form field data "bound" to XML nodes?RP,

Thank you for your response.

One problem I am having is that the form elements on the web page need to
have unique names, but the values might be destined for elements with the
same name. So I cannot simply name the form field to correspond with the
element name in the XML document. Furthermore, a particular element might
appear multiple times nested at different levels within the XML document.
How will I know that form field "foo1" should populate the first <foo>
element and form field "foo2" populate the second in the example below:

    <foo>["foo1" goes here]</foo>
        <foo>["foo2" goes here]</foo>

I am trying to hard-code as little as possible into the Java code while
avoiding having form fields with ridiculously long and complex names.

  if it is coming as a HTTP request you can take the request object and
convert it into an XML message.

  Step1: Get the request object(HTTPRequest).
  Step2: From the request object get the name value pairs using the methods
of the HTTPRequest     object.
  Step3: Form the XML the way you want.

  you can actually write java methods where in you can just input the name
value pair as parameters and it builds the XML and keeps on appending the
new name value pairs.

  if you want more details please write back.

  Is there an easy way for form field data sent from a web page to populate
  nodes in an XML file? I am trying to deal with the problem of
  non-hierarchical data (name/value pairs sent from the form) having to find
  its way into a hierarchical data structure (the XML file) on the server
  side. To my knowledge, web browsers can only send form data via HTTP as
  name/value pairs.

  My only thoughts so far have been to devise a (ridiculously) complex
  scheme for the form element names that would somehow correspond to an
  expression, or to build a JavaScript object representing the data
  that could be serialized into XML and sent as the sole name/value pair.
  These seem to me to be very kludgey.

  There must be an easier way. Any ideas?
