root     = xmlDocGetRootElement(document);

fprintf(stdout, "Root is <%s>\n", root->name);


first_child = root->children;
for (node = first_child; node!=NULL; node = node->next){

     grand_child=node->children;

        for (node2= grand_child; node2!=NULL; node2 = node2->next){
            fprintf(stdout, "\tGrand_Child is <%s>\n",node2->name);
            sibling=node2->children;

            for (node3= sibling; node3!=NULL; node3 = node3->next){
               fprintf(stdout, "\t Sibling is <%s>\n",node3->name);
            }

        }

return 0;}

如果您不想要文本节点，则只打印类型为XML_ELEMENT_NODE的节点。也就是说，打印代码应首先检查type字段：

if (node->type == XML_ELEMENT_NODE) {
    fprintf(stdout, "\t Child is <%s>\n", node->name);
}

用C语言打印XML格式的节点
