Validating xml with xsd c
If you want to see them, derive your own class from it and handle the error() method.
Furthermore, in order to use schema, you should invoke set Do Schema(true) Finally, change the set External Schema Location to be set External No Namespace Schema Location (or, if is using a target Namespace, change the argument of set External Schema Location to be "uri schema.xsd") Alberto evangeline wrote: So, I should declare a class that looks like this: class XMLValidate Error : public Handler Base ; XMLValidate Error:: XMLValidate Error() void XMLValidate Error::error(XMLException &e) and then: XMLValidate Error *err_handler = new XMLValidate Error(); But I still don't get any error messages and it still always returns true..thoughts ? Correct the signature and you will get the error event.
Dave --------------------------------------------------------------------- To unsubscribe, e-mail: [hidden email] For additional commands, e-mail: [hidden email] We've tried the above code and it does not validate the XML file. Here is the hacked code: /* initialize xerces system before usig API: DOM, SAX, SAX2 */ try catch (const XMLException &e) /* actual xerces work */ char *xml_file = "D:\Development\Chronicle\Example Schemas and Form Templates\Drill Data_1.xml"; char *xml_schema = "D:\Development\Chronicle\Example Schemas and Form Templates\new Drill Data.xsd"; SAXParser *parser = new SAXParser(); CSax Parser Error Handler error Handler; parser-set Do Namespaces(true); try catch (const XMLException &e) catch(...) delete parser; //delete doc_handler; /* terminate and cleanup */ XMLPlatform Utils:: Terminate(); The XML file purposefully has an extra element which is not allowed by the schema. Here is the quickly knocked together error handler: class CSax Parser Error Handler : public xercesc_3_0:: Error Handler ; void CSax Parser Error Handler::warning(const SAXParse Exception& exc) void CSax Parser Error Handler::error(const SAXParse Exception& exc) void CSax Parser Error Handler::fatal Error(const SAXParse Exception& exc) It looks you didn't read my e-mail; I said "Furthermore, in order to use schema, you should invoke set Do Schema(true) Finally, change the set External Schema Location to be set External No Namespace Schema Location (or, if is using a target Namespace, change the argument of set External Schema Location to be "uri schema.xsd") " Alberto Leif Goodwin ha scritto: These are not valid URLs, because URLS cannot contain the space character, nor the '\' character.
Instead, put these files in a directory with no space, and reference to them with legal URLs: file:///Development/Chronicle/Example/new Drill set External Schema Location(xml_schema); As Alberto pointed out, this function does not accept a URL, it accepts a URI/URL pair. The second is the URL for the schema document itself.
Test XML file: As you can see the schema allows some attributes and no child elements.
Decoders provide validation of incoming XML documents, and fast transformation of those documents to values of the C/C representations.Take advantage of the merging of two complementary technologies: XML and ASN.1. Encode XML messages into highly compact binary encodings and send them down the line for lossless decoding. The OSS XSD Tools bind your XSD Schema to C/C representations., with standardized binary encoding support, allow you to do just that, by providing runtime functions to quickly encode/decode XML data to/from very compact ASN.1 binary encodings. Runtime libraries provide fast encoding of values of these representations into highly compact binary or XML encodings.See here for more information: the schema does not use a namespace, then call set External No Namespace Schema Location() with just the URL for the schema document.I would suggest you try running the SAX2Print sample application in the debugger and see what that code does.
