Hi Radu, Thanks for the reply. I admit that I may very well be misinterpreting the Javadocs in terms of what SchemaType covers.
Here is my overall goal: - Given a set of schemas, generate a set of element types. Then, whenever an element type is retrieved from this set (my code manages that retrieval mechanism), be able to determine all child element types/attribute types (and recurse through those as necessary to fully defined the structure of the element type). To do this today, I'm using XmlBeans.compileXsd(), and taking all of the SchemaTypes (via typeSystem.documentTypes(), typeSystem.attributeTypes(), and typeSystem.globalTypes()) out of the resultant SchemaTypeSystem and putting them into an ArrayList. Then I can search through that ArrayList for whatever element type I'm interested in. However, once I retrieve the SchemaType of interest, I am having difficulty accessing its children (element types and attribute types). My current approach is based loosely on the example in the Javadocs (see http://xmlbeans.apache.org/docs/2.2.0/reference/index.html) that starts "The following code is a standard treewalk...". The problem I had with Lawrence's post was that when I called getProperties() on the SchemaType I was interested in, it didn't return an array of the expected size. From the schema example I provided last time (where the "Compliance" element type should have two child types), the result from getProperties() was an array of size 1 (instead of the expected size of 2), and the one entry didn't seem to have a name (or at least I couldn't retrieve it via getName(), which gave null). I'm sure I'm making a mistake in my approach somewhere, in particular because you've mentioned that SchemaTypes don't represent elements (I assume you mean "element types"). Could you please provide some general direction on how I can approach the problem I'm trying to solve?
