  • decide which XML Schema validator to use

choice: Castor because it supports both code generation and class mapping, because it's open source, because it's actively developed, and because it's reasonably reviewed.

  • technology:
  • SAX: Simple API for XML

Does not produce representation in memory [1]

example validation [http://www.oracle.com/technology/pub/articles/vohra_xmlschema.html http://www.oracle.com/technology/pub/articles/vohra_xmlschema.html]

  • DOM: Document Object Model

Produces in-memory representation. Validates structure but not content. [2]

example validation [http://www.oracle.com/technology/pub/articles/vohra_xmlschema.html http://www.oracle.com/technology/pub/articles/vohra_xmlschema.html]

  • XSD: XML Schema Design validator

Does not validate parsing. [http://www.oracle.com/technology/pub/articles/vohra_xmlschema.html http://www.oracle.com/technology/pub/articles/vohra_xmlschema.html]

example validation [http://www.oracle.com/technology/pub/articles/vohra_xmlschema.html http://www.oracle.com/technology/pub/articles/vohra_xmlschema.html]

Not clear whether creates in-memory objects. Not clear whether any easier than DOM.

  • JAXB: better than SAX, DOM

Less able to handle dynamic structures. Input is XMLSchema. * [3]

  • JAXP: Java API for XML Processing

Abstraction layer for XML processor independance. [4]

[5]

  • options:
  • xerces-j [6]

debian package libxerces-java Supports SAX, DOM

  • xerces2-j [7]

debian package libxerces2-java libxerces2-java-doc Supports SAX, DOM, JAXP

  • castor [8]open source. recent activity.

Java class/XML/SQL transforms

supports mapping existing classes or generating new classes.

  • JAXB [11]Java Community Standard

Supports generating new classes.

  • JaxMe[12][13]OpenSource implementation of JAXB

validate, build java representation rigid, deeper support for XML. Supports generating new classes. comparison [http://www-106.ibm.com/developerworks/library/x-databdopt/index.html http://www-106.ibm.com/developerworks/library/x-databdopt/index.html]

command line tools are/were using not clear it generates an in-memory image.

http://qare.sourceforge.net/web/2001-12/products/quick/index.html]uses DTD no XMLSchema. very flexible. complex schemas. poor forum support. Supports mapping existing classes or generating new classes. comparison [http://www-106.ibm.com/developerworks/library/x-databdopt/index.html http://www-106.ibm.com/developerworks/library/x-databdopt/index.html]

  • Zeus [16]Supports strings only. Limited heirarchy support. Supports

generating new classes. comparison [http://www-106.ibm.com/developerworks/library/x-databdopt/index.html http://www-106.ibm.com/developerworks/library/x-databdopt/index.html]
