XML Schmema parser / validator

Hi, since I've written my first line of code using the PEAR SOAP Server and Client code I'm dreaming of a standalone XML Schema parser / validator. Maybe I've been told to much Java or I'm making things much more complex but required, but... However: if I had a standalone XML Schema parser it would soon play an important role within my applications. Think of a set of pages looking almost the same: fetch data (list of orders) from a data source (database), present it, allow the user to edit a record and write the changes back to the data source. When writing back to the data source two tasks have to be performed: 1) check for valid data types and 2) - if using a relational database system - check relations. I'd like to handle 1) using a XML Schmema parser. This would reduce the amount of work the editing page requires: - writing some XML describing the form - writing some XML describing the data types of the form elements - writing a template to dump the form and finally: $login_bean = new login_bean(); $form = new template_form( new xml_form('form.xml'),

                                            new schmema_validator('datatypes.xml')
                                         );

$form->setValues($login_bean->getRecord(13)); if ($form->isValid()) { $err = $login_bean->checkRelations($form->getValues()); if (!is_empty($err)) $form->setErrors($err); else

    $login_bean->save($form->getValues());

} $form->show('form_template.html'); ... just some JAPHA dreams. Maybe someone reminds this when working on the SOAP stuff. ;-) Ulf
