Re: [xml] DAV: namespace and xmlReader

[Aleksey Sanin <aleksey aleksey com>]

You can overwrite error handler and reset the error manualy
(yes, I know this is ugly :( ):

static void
XmlStructuredErrorHandlerNoWarning (void * userData, xmlErrorPtr err)
{
    // WebDAV uses "bad" URIs for namespaces. We need to ignore
    // this error
    if(err && err->code == XML_WAR_NS_URI &&
       err->level == XML_ERR_WARNING) {
        if((err->domain == XML_FROM_PARSER) ||
           (err->domain == XML_FROM_HTML) ||
           (err->domain == XML_FROM_DTD) ||
           (err->domain == XML_FROM_NAMESPACE) ||
           (err->domain == XML_FROM_IO) ||
           (err->domain == XML_FROM_VALID)) {
        
           xmlParserCtxtPtr ctxt =
               static_cast<xmlParserCtxtPtr>(err->ctxt);
           if(ctxt) {
               ctxt->errNo = XML_ERR_OK;
           }
        }
    }

    if (! err ||
          err->code == XML_ERR_OK ||
          err->level == XML_ERR_WARNING)
        return;

    XmlStructuredErrorHandler (userData, err);
}
