Just wanted to update that succeeded in creating the Citation manager - http://formidablepro.com/help-desk/citation-manager-add-on/

The form fetch the XML data from pubmed collect it in a table and publish a post.

this it the main code I wrote:

Use this code to add an OnClick event to a particular submit button.

This code will get all the specified fields and display them on the last page of the form. These fields will still appear in their normal position as well.
