   RE: [xml-dev] Looking for a schema->html form XSL transform

[ Lists Home | Date Index | Thread Index ]

How is an XML Schema non-generative?

There are top level elements that show what the root element is. This element has a type, which has child elements, etc.

If there are multiple top level elements in the schema, just pass in a parameter to the stylesheet with the name of the root element you want in your result document and follow the tree all the way to the end.

See  http://www.xml.com/pub/a/2003/01/15/transforming-schemas.html?page=1, or the "User Interface Generation" chapter from the following paper, which describes how one can generate an XForms from a schema using XSLT (and borrowed heavily from the examples in the xml.com article): http://dream.sims.berkeley.edu/CDE/report/go-five-final-report.html

An XML Schema is not generative; i.e., doesn't have enough information in it
to provide the basic structure of a document, so you need to start with
something that says what the root element it, what elements come next, etc.

If you start with a sample XML document with blanks for the content, then
you can use any XForms processor to do what you're asking.  You do need to
provide the human-readable labels for the fields you want the user to edit,
and an XPath expression that says where those fields are in the initial
document.  If you specify one or more XML Schemas, they will be used to
validate the resulting document before it is POSTed back as XML.  

See http://www.w3.org/MarkUp/Forms and
http://www.w3.org/MarkUp/Forms/Test/ImplementationReport.html two
fully-conformant implementations, one of which runs inside Internet
Explorer.  There are also some JavaScript-based implementations; they aren't
fully conformant with the XForms spec, but might be good enough for your
purposes.  IBM has one available form download and testing.

I want to:
1. Use XSL to build a HTML form from a schema, then
2. Build XML from the elements in the form and POST the xml back to a

Does anyone know of XSL or javascript I can use which will address either of

the above?
