Javascritp(用戶端) XPath 初試– load xml document

下面是根據XPath教程的一次查詢嘗試！

  <script type="text/javascript">        function loadXMLDoc(fileName) {            if (window.XMLHttpRequest) {                xhttp = new XMLHttpRequest();            }            else {                //IE5                 xhttp = new ActiveXObject("Microsoft.XMLHTTP");            }            xhttp.open("GET", fileName, false);            xhttp.send("");            return xhttp.responseXML;        }        xml = loadXMLDoc("Book.xml");        var path = "/bookstore/book/title";        if (window.ActiveXObject) {            var nodes = xml.selectNodes(path);            for (i = 0; i < nodes.length; i++) {                document.write(nodes[i].childNodes[0].nodeValue);                document.write("<br/>");            }        }//Firefox之類瀏覽器        else if (document.implementation && document.implementation.createDocument) {            var nodes = xml.evaluate(path, xml, null, XPathReslt.ANY_TYPE, null);            var result = nodes.iterateNext();            while (result) {                document.write(result.childNodes[0].nodeValue);                document.write("<br/>");                result = nodes.iterateNext();            }        }    </script>
