示例1: createExpression
/**
* Creates a parsed XPath expression with resolved namespaces. This is
* useful when an expression will be reused in an application since it
* makes it possible to compile the expression string into a more
* efficient internal form and preresolve all namespace prefixes which
* occur within the expression.
*
* @param expression The XPath expression string to be parsed.
* @param resolver The <code>resolver</code> permits translation of
* prefixes within the XPath expression into appropriate namespace URIs
* . If this is specified as <code>null</code>, any namespace prefix
* within the expression will result in <code>DOMException</code>
* being thrown with the code <code>NAMESPACE_ERR</code>.
* @return The compiled form of the XPath expression.
* @exception XPathException
* INVALID_EXPRESSION_ERR: Raised if the expression is not legal
* according to the rules of the <code>XPathEvaluator</code>i
* @exception DOMException
* NAMESPACE_ERR: Raised if the expression contains namespace prefixes
* which cannot be resolved by the specified
* <code>XPathNSResolver</code>.
*
* @see org.w3c.dom.xpath.XPathEvaluator#createExpression(String, XPathNSResolver)
