verifying domdocument

[Jairam, Roopnaraine]

Hi all,   I have a function that takes a domdocument* and writes it to the xml file. My question is can I verify that the document adheres to my schema before I save it. I have created xml documents that were invalid (while debugging) according to my schema, but I didn't know it until I parsed the xml doc.   DWORD XML::writeToFile(xercesc::DOMDocument* document) {       DWORD status = ERROR_SUCCESS;         if (document == NULL)             return ERROR_INVALID_HANDLE;       XMLCh tempStr[100];     XMLString::transcode("LS", tempStr, 99);     DOMImplementation *impl = DOMImplementationRegistry::getDOMImplementation(tempStr);     DOMWriter* theSerializer = ((DOMImplementationLS*)impl)->createDOMWriter();     XMLCh* utf16str = NULL;     const XMLByte* str = NULL;       // optionally you can set some features on this serializer     if (theSerializer->canSetFeature(XMLUni::fgDOMWRTDiscardDefaultContent, true))         theSerializer->setFeature(XMLUni::fgDOMWRTDiscardDefaultContent, true);       if (theSerializer->canSetFeature(XMLUni::fgDOMWRTFormatPrettyPrint, true))             theSerializer->setFeature(XMLUni::fgDOMWRTFormatPrettyPrint, true);     LocalFileFormatTarget myFileTarget( m_xmlFileName );       try     {         theSerializer->writeNode( &myFileTarget, *document);       }     catch (const XMLException& toCatch)     {             status = ERROR_CANTWRITE;       }     catch (const DOMException& toCatch)     {             status = ERROR_CANTWRITE;     }     catch (...)     {             status = ERROR_CANTWRITE;     }       theSerializer->release();       return status; }   Vince.
