RES: Can´t acess child elements definition

[Rubens Del Monte]

Title:

Max (and anybody who can help me),      I tried out that but it result in a java.lang.ClassCastException.. the code is this :   XMLParserConfiguration config = new StandardParserConfiguration();             config.setProperty("http://apache.org/xml/properties/internal/grammar-pool",grammarPool);             DOMParser parser = new DOMParser(config);             parser.setFeature("http://xml.org/sax/features/validation",true);             parser.setFeature("http://apache.org/xml/features/validation/schema",true);             parser.parse(filename);             doc = parser.getDocument();                          org.apache.xerces.impl.xs.psvi.XSModel model = grammarPool.toXSModel();                         XSElementDeclaration elem = ((XSModelImpl) model).getElementDeclaration("os",null);               // this line ocurrs the exception.. the XSElementDeclaration cannot be casted into a ((ElementPSVI             XSElementDeclaration elemson = ((ElementPSVI) elem).getElementDeclaration();   I �ve been looking into the xerces documentation but I still havent found a way to get the XSElementDeclaration that are child of a XSElementDeclaration.   Thanks,   Rubens Del Monte       -----Mensagem original----- De: Maksym Kovalenko [mailto:[EMAIL PROTECTED] Enviada em: ter�a-feira, 7 de outubro de 2003 16:53 Para: [EMAIL PROTECTED] Assunto: Re: Can�t acess child elements definition   For child element you can extract its declaration as the following XSElementDeclaration elDecl = ((ElementPSVI) childElement).getElementDeclaration(); The error in the code you've provided is that to get element declaration for child elements you need to process content of the root element. model.getComponents(XSConstants.ELEMENT_DECLARATION); contains only information for elements defined in the schema's top level.

They don�t have namespace too… XSElementDeclaration elem = ((XSModelImpl) model).getElementDeclaration("os",null); …. If anyone can help me, please, I�ve been trying to do this but it�s taking too long… Thanks, Rubens Del Monte   -- Maksym Kovalenko Software Engineer Marketswitch Corporation http://www.marketswitch.com 108 Powers Court, Suite 225 Dulles, VA 20166 Phone: +1 (703) 444-6750 ext. 302 Fax: +1 (703) 444-6812
