how to read a part of xml file in C++ using Libxml2

Question

Hello i need to know "how to read a part of xml file in C++ using Libxml2". In my xml file I have :

<svg>
    <g>
       <path d="11"/>
    </g>
</svg>

I want to see a value of "d" on my c++ program, when I come to this point :

   xmlNode *cur_node = NULL;

    for (cur_node = a_node; cur_node; cur_node = cur_node->next) {

      if(xmlStrEqual(xmlCharStrdup("path"),cur_node->name)){


            printf("element: %s
", cur_node->name);
        }

        print_element_names(cur_node->children);
    }    
}

I dont know what I need to do, please help me.

I'm not sure I understand the question, but it sounds like you want to print the attribute "d" in the element "path". In the code above, you need something like this:

xmlChar *d = xmlGetProp(cur_node, "d");
... do something ...
xmlFree(d);
