Attributes are very similar to child nodes. The same data can be stored in a child node or in an attribute.
For example, you can use
<node><a>xxx</a></node>
or
<node a="xxx"></node>
Child nodes are more universal and extensible than attributes. But with attributes the xml is smaller. I sometimes use children, sometimes attributes. Maybe need more experience to decide which and when is better. Also read a couple of XML tutorials on the web.
