Parameters

tr: [input]A tree branch node that we need to scan for
strTag: [output]result tagName

the enumeration index of the tag if successful, or -1 if tr is not a branch

Examples

void tree_get_next_enum_tag_name_ex1()
{        
    Tree tr;
    tr.AddNode("Node1");
    tr.AddNode("Node2");
    tr.AddNode("Node3");
 
    string strNextTagName;
    int nn = tree_get_next_enum_tag_name(tr, strNextTagName);
    out_str(strNextTagName);
