Hi there i m trying to attach some values, such as node_order,node_depth and node_size, to each and every node in the DOM tree i parsed. The reason being those values are to be stored in RDBMS together with the nodes' name etc. The problem is that i couldn't extend or implement those nodes to allow me to add additional values other than those already defined. As the node_size for each node has to be calculated from previous sibling and parent, i will need to store those values directly onto the nodes. After which normal dom traversal will allow me to calculate the correct node_size for each nodes. pls let me know if there is another way to accomplish my objectives. thank you Max    More>>
