// This will grab all form elements on your page, and build an XML string out of their current values.
// Each item needs a valid ID.  The XML node will be named after the item's ID.
// If you have HTML editor windows, you need to list them as the second paramater, after they've all been initialized.
// The second paramater expects data in an object built like an associative array, with the key for the entry being what
// you would like the XML node to be named (i.e. "pageText" or "newsletterBody") and the entry's value being the editor object
// (most likely oEdit0, if you've used the 'initializeWYSIWYG' method)
//
// EX: I have my NewModule textContent attribute in a wysiwg, and I'm doing AJAX-style saving.
// var editorFields = {'textContent': oEdit0};
// var xmlString = getXmlFromPageElements('moduleItem', editorFields);
// this.ro.connect(this.script, "POST", xmlString, this.handler);
