int main()

    xmlFreeDoc(doc);

    return(0);
}

Output Screenshot

XML version is 1.0
XML encoding is UTF-8

Notes

* If the prolog information isn't available, NULL pointers are returned for the version and encoding members of the xmlDocPtr structure. Ensure that you test for this possibility in your code.
