If the requirement is simply to show a form based on an XML file, let the user edit it, validate it, and then save the updates, then this can be easier done with a simple pipeline and I see no reason to deal with a yet another framework outside of Cocoon.
Here is an example:
- I have an XML document
- I want to prepopulate an HTML form and present it to ther user based on the values in document
- The user edits the form and clicks "Save"
- The values are extracted out of POST parameters and saved back to the original document.
First two points are trivial, because all one needs to do is transform original document into an HTML form.
The remainder is tricky. I accomplished this by setting up an internal pipeline that uses RequestGenerator to create an XSL transform called "update.xsl" that applies the changes to the original document. To know which form values go to which places in the original document I used xpaths of the original elements and attributes as names for input fields. So, an XSL can be generated that applies the changes to the original doc and wraps it in something that SOurceWritingTransformer can understand.
Is there a Cocoon solution that would let me easily set up a form that essentially edit XML w/o all of the aforementioned convoluted XSLTs ? To rephrase -- is there a way to map XML document onto an HTML form and then apply the changes back to the original document other than what I mentioned ? Would Chicoon or Woody be helpful ?
Of course! This is exactly what Woody can do for you. Have a look on the binding sample which changes an XML file.
