Re: [xml-dev] better (?) than DOM

Not exactly what you are looking for, but System.Xml shipped a streaming validation API that provides for such things as expected elements in the V2.0 release (VS 2005).  It is used by the XML Editor in VS for schema-based intellisense.

Building something equivalent for Xerces would be non-trivial.  Xerces validation DFA does not provide links back to the original Element Declarations (which can be useful for looking up meta-data in the appinfo blocks).  Also, the typed-data support in Xerces seems less complete.  I used it to build a schema-aware xml canonicalizer (kinda) and had to hack around a number of minor issues.

Talking of convenience I have recently been building messages based on
XML Schemas using the XERCES XML Schema API. I think it too could use
some shortcuts. Even what to me seem relatively simple, and probably
common queries like getting a list of the allowable children of an
element can (by the time you check decleration types and the like) take
about 15 method calls.

Does anyone know of any projects that provide more user friednly API's
for XML Schema (preferably still fitting within the Xerces
architecture)?
