This week, Mark came back from the XForms Working Group face-to-face meeting with news of a potential new XForms feature--the ability to handle non-XML responses from submissions.
The motivation for this feature is that there are many services that don't return XML, but which are crucial to an application; if the form author has no control over these services then it is important to be able to process the non-XML responses. In standard XForms there is no way to get to the response.
(A good example of such a service is the GData authentication mechanism.)
The mechanism for handling this is by defining an additional value for the
replace attribute on
text), and a new attribute telling the
processor whereabouts in the instance data to insert the retrieved data
<model> <instance id="inst"> <x><y /></x> </instance> <submission method="get" action="http://www.example.com/SomeTextFile.txt" replace="text" target="y" /> </model>
In this example, the contents of
SomeTextFile.txt would be loaded into the
y in the instance.
[submission-text- target.html](http://svn.x-port.net/svn/public/samples/submission/submission- text-target.html) demonstrates the use of these new attributes to insert both text and XML into an instance document. A more in-depth look at this feature can be seen in submission with replace="text", and the target attribute in Using formsPlayer.
