Hi Richard! Which version of Xerces are you using? I switched to 2.2.0, lately, and encountered the same problem. Unfortunatelly, I've touched my code, too. So it took me quite a while to find the reason. Switching back to 2.0.2, everything works fine.

I tried using an EntityResolver--it's called, but the error [Error] :2:273: cvc-elt.1: Cannot find the declaration of element 'didl:DIDL'. is encountered even BEFORE my EntityResolver returns. I'm think the problem is with imported schemas. The following directly declares the root element and does NOT generate an error: ------------------------------------------ EXAMPLE 1 -------------------------------------------------------------- rootTest.xml: <?xml version="1.0" encoding="UTF-8"?> <f:root xsi:schemaLocation="http://simple F:/MyProjects/SCRPG/rootTest.xsd" xmlns:f="http://simple"; xmlns="http://simple"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";> TEST </f:root> F:/MyProjects/SCRPG/rootTest.xsd: <?xml version="1.0" encoding="UTF-8"?> <xs:schema targetNamespace="http://simple"; xmlns="http://simple"; xmlns:xs="http://www.w3.org/2001/XMLSchema";> <xs:element name="root" type="xs:string"/> </xs:schema> ---------------------------------------------------------------------------- --------------------------------------- ------------------------------------------ EXAMPLE 2 -------------------------------------------------------------- However, if I put the definition of element 'root' into a second schema and import it into the first schema, it doesn't work: ---------------------------------------------------------------------------- --------------------------------------- rootTest.xml: <?xml version="1.0" encoding="UTF-8"?> <f:root xsi:schemaLocation="http://simple F:/MyProjects/SCRPG/rootTest.xsd" xmlns:f="http://imported"; xmlns="http://simple"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";> TEST </f:root> F:/MyProjects/SCRPG/rootTest.xsd: <?xml version="1.0" encoding="UTF-8"?> <xs:schema targetNamespace="http://simple"; xmlns="http://simple"; xmlns:xs="http://www.w3.org/2001/XMLSchema";> <xs:import namespace="http://imported"; schemaLocation="F:/MyProjects/SCRPG/rootTest2.xsd"/> </xs:schema> F:/MyProjects/SCRPG/rootTest2.xsd: <?xml version="1.0"?> <xs:schema targetNamespace="http://imported"; xmlns="http://imported"; xmlns:xs="http://www.w3.org/2001/XMLSchema";> <xs:element name="root" type="xs:string"/> </xs:schema> ---------------------------------------------------------------------------- ------------------------------------------- The above files validate fine in XMLSpy, but I get the error: [Error] :2:181: cvc-elt.1: Cannot find the declaration of element 'f:root'. using "org.apache.xerces.parsers.SAXParser". And my EntityResolver isn't called at all, so I presume the files are being located OK. -----Original Message----- From: Amthauer, Heiner [mailto:[EMAIL PROTECTED] Sent: Tuesday, October 15, 2002 11:52 PM To: '[EMAIL PROTECTED]' Subject: AW: [Error] :2:273: cvc-elt.1: Cannot find the declaration of element 'didl:DIDL'. Hi! I would assume that the file is not validated at all. Therefore, it parses fine. I had the same problem with getting XML and schema to work, using the sax parser. There are a few ways to act about this: - use an EntityResolver (doesn't work for me yet, and nobody was able to explain why) - tell the sax parser to use schema. This is done by setting the schema property - tell the sax parser, which schema to use, explizitly. and, last but not least, use URI syntax for the schema: file:///f:/myprojects/scrpg/scr_02.xsd <file:///f:/myprojects/scrpg/scr_02.xsd> The following works for me: In the xml file, do not reference the schema file. Use the following in your code: ... private static final String FLAG_VALIDATE = " http://xml.org/sax/features/validation <http://xml.org/sax/features/validation> "; private static final String FLAG_SCHEMA = " http://apache.org/xml/features/validation/schema <http://apache.org/xml/features/validation/schema> "; private static final String FLAG_NAMESPACE = " http://xml.org/sax/features/namespaces <http://xml.org/sax/features/namespaces> "; private static final String PROP_SCHEMA = " http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation <http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation> "; ... saxParser.getXMLReader().setFeature(FLAG_VALIDATE, validate); if (null != schema) { saxParser.getXMLReader().setFeature(FLAG_SCHEMA, true); saxParser.getXMLReader().setFeature(FLAG_NAMESPACE, true); saxParser.setProperty(PROP_SCHEMA, schema); } ... where 'schema' is a string, containing the URI. The above code has one major disadvantage: setting the schema explizitly means, that you have to know which one to use (unless you are parsing alway the same file). If you find out a better way, please let me know, too. Greetings Heiner -----Urspr�ngliche Nachricht----- Von: Richard Moster [mailto:[EMAIL PROTECTED] Gesendet am: Mittwoch, 16.

I have an XML file, referencing a schema that in turn imports another schema. When I use the SAX2 parser to parse with validation, I'm getting the following error: [Error] :2:273: cvc-elt.1: Cannot find the declaration of element 'didl:DIDL'. didl:DIDL is the root element of the XML file and is declared in the imported schema (see below).
