Examples of javax.xml.xpath.XPath.compile()

javax.xml.xpath.XPath.compile()

Compile an XPath expression for later evaluation.

If expression contains any {@link XPathFunction}s, they must be available via the {@link XPathFunctionResolver}. An {@link XPathExpressionException} will be thrown if the XPathFunctioncannot be resovled with the XPathFunctionResolver.

If expression is null, a NullPointerException is thrown.
@param expression The XPath expression. @return Compiled XPath expression. @throws XPathExpressionException If expression cannot be compiled. @throws NullPointerException If expression is null.
