How to get required vs optional from a schema?

[Adam Flinton <ad...@nhs.net>]

Dear All,

I am trying to build something which adds all required elements and
required attributes to a document but then gives a user a choice of
adding those child elements/attributes which are optional (via a web
app/gui).

So I have been looking walking the tree much as the
org.apache.xmlbeans.impl.xsd2inst.SampleXmlUtil does (except storing
elements etc into a dom structure).

So my question is:

If I find myself on an SchemaType (Element), how do I ask "what are my
required child nodes (elements & attribs)?" and "what are my optional
child nodes (elements & attribs)?"

TIA

Adam

Hi Adam,

There is no API to get that directly, but it is easy to get the info using SchemaType.getProperties(). Then, iterate over all properties, checkin for those that have .getMinOccurs() > 0. You get both elements and attributes, aggregated.
