Parsing issue with libxml2: Namespace error

I have a problem of parsing my xml file, it is not correct with libxml but it's certified valid by the owner of application.

I have tried to read the RFC to XOP but seems don't related with my problem. And i don't understand how to implement others solutions in my code.

int main(int argc, char **argv) {

   char         *docname;
   xmlDocPtr    doc;
   xmlNodePtr   cur;
   xmlChar      *date;

   if (argc < 2) {
     printf("Commande: %s nom_du_fichier\n", argv[0]);
     return EXIT_FAILURE;
   }


   docname = argv[1];

   doc = xmlParseFile(docname);
   cur = xmlDocGetRootElement(doc);

   cur = cur->xmlChildrenNode;
   while (cur != NULL) {
       if ((!xmlStrcmp(cur->name, (const xmlChar *)"anpr"))) {
         date = xmlGetProp(cur, "date");
         printf("date: %s\n", date);
         xmlFree(date);
       }
       cur = cur->next;
   }
   xmlFreeDoc(doc);
   return EXIT_SUCCESS;
}

Code xml:

<msg><tag date="1556896362471" session="1702"><jpeg><xop:Include href="A"/></jpeg>/msg>

file.xml:1: namespace error : Namespace prefix xop on Include is not defined

This tag has not useful but i can't remove manually each time.

If the XML file is exactly as it appears in your question, then the owner of the application is wrong. Any conformant XML parser will encounter a fatal error trying to parse that XML.

I have tried to read the RFC to XOP but seems don't related with my problem.

You're correct, the details of XOP are unrelated to this lower-level problem.

It may be worth learning the basics XML Namespaces, so you can better understand why that XML is not well-formed (specifically the xmlns attribute). https://www.w3schools.com/xml/xml_namespaces.asp
