NODE); By using this kind of expressions we can filter for whatever element we need to look for just by using the correct syntax.

We can look for an element based on any given id just by filtering: Document Builder Factory builder Factory = Document Builder Instance(); Document Builder builder = builder Document Builder(); Document xml Document = builder.parse(File()); XPath x Path = XPath Instance()XPath(); String expression = "/Tutorials/Tutorial[@tut Id=" "'" id "'" "]"; node = (Node) x Path.compile(expression).evaluate(xml Document, XPath Constants.

It uses DOM, so it is perfect for easily updating Ant build scripts or any kind of configuration files during the automation of some setup that happens routinely, which is exactly what I'm up to here.
