CHAPTER 6 Navigating XML with XPath > Processing XPath in Java
Processing XPath in Java
Let’s look at how to perform streaming XPath-based XML content evaluation.
The following example calls Oracle XDK to evaluate the XPath expression without building a DOM object in memory. The example only works on a subset of XPath functions and axes (including child, descendant, attribute, text, parent, and ancestor).
