Examples

EX1 

void TreeNode_GetAttribute_ex1()
{
    Tree tr;
    TreeNode tn1;
    tn1 = tr.AddTextNode("Staff", "Infomation", 2); 
    out_tree(tr);
    
    tn1.SetAttribute("name", "Amy");	//New a string attribute named "name" and set to "Amy"
    tn1.SetAttribute("age", 33);		//New a int attribute named "age" and set to "35"
    tn1.SetAttribute("salary", 5303.56);//New a double attribute named "salary" and set to "5303.56"
    
    // Gets the string attribute of a node with its name.
    string strVal;
    if ( tn1.GetAttribute("name", strVal) )
