XPath is not traditionally considered a data binding API. It doesn't even get much attention in the XML world, except in passing as part of other specifications. But once you fully understand what XPath is and how to use it -- particularly in a Java™ programming environment -- it becomes a powerful data binding tool that's often preferable to traditional data binding APIs such as JAXB or JaxMe. Brett McLaughlin's Practical data binding column returns with the first in a two-article series that examines XPath as a data binding tool.
