Xerces c validating xml parser nigerian dating scam facebook
One reason could be that you plugged a Handler Base as Error Handler, and that will throw an exception only in presence of a fatal error (validation errors as hence ignored).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.xerces-c: xerces-c (a validating XML parser) xerces-c: xerces-c: Xerces-C is a validating XML parser written in a portable subset xerces-c: of C .
A shared library is provided for parsing, generating, manipulating, and validating XML documents using the DOM, SAX, and SAX2 APIs.Source code, samples and API documentation are provided with the parser.For portability, care has been taken to make minimal use of templates, no RTTI, and minimal use of #ifdefs.by Q Ethan Mc Callum 09/08/2005 From data storage to data exchange and from Perl to Java, it's rare to write software these days and not bump into XML.Adding XML capabilities to a C application, though, usually involves coding around a C-based API. Adopt the Xerces-C parser and you can skip these middlemen.
Otherwise what use is it to know that the XML the application is about to process is valid with regards to some schema?
