Question

我正在做一个Phonegap应用程序，我想使用xml文件，即我想在xml中搜索特定节点。我使用的xml文件如下所示。

<bookstore>
  <book category="cooking">
  <title lang="en">Everyday Italian</title>
  <author>Giada De Laurentiis</author>
  <year>2005</year>
  <price>30.00</price>
  </book>
  <book category="children">
  <title lang="en">Harry Potter</title>
  <author>J K. Rowling</author>
  <year>2005</year>
  <price>29.99</price>
  </book>
  <book category="web">
  <title lang="en">Learning XML</title>
  <author>Erik T. Ray</author>
  <year>2003</year>
  <price>39.95</price>
 </book>

在这里，我想搜索图书的类别并显示该图书的所有详细信息。如果我搜索类别＆＃34; web＆＃34;，它将返回具有类别＆＃34; web＆的图书的详细信息＃34;

提前致谢.....

var xml = "<bookstore><book category='cooking'>aaaa</book></bookstore>";

如果您不想使用任何JavaScript库，可以试试这个：

<script type="text/javascript">
    function loadXMLString(txt) {
        if (window.DOMParser) {
            parser = new DOMParser();
            xmlDoc = parser.parseFromString(txt, "text/xml");
        } else // Internet Explorer
        {
            xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
            xmlDoc.async = false;
            xmlDoc.loadXML(txt);
        }
        return xmlDoc;
    }

    window.onload = function () {
        text = '<bookstore>' 
               + '<book category="cooking">' 
               + '<title lang="en">Everyday Italian</title>' 
               + '<author>Giada De Laurentiis</author>' 
               + '<year>2005</year>' 
               + '<price>30.00</price>' 
               + '</book>' 
               + '<book category="children">' 
               + '<title lang="en">Harry Potter</title>' 
               + '<author>J K. Rowling</author>' 
               + '<year>2005</year>' 
               + '<price>29.99</price>' 
               + '</book>' 
               + '<book category="web">' 
               + '<title lang="en">Learning XML</title>' 
               + '<author>Erik T. Ray</author>' 
               + '<year>2003</year>' 
               + '<price>39.95</price>' 
               + '</book>' 
               + '</bookstore>';

        xmlDoc = loadXMLString(text);

        x = xmlDoc.getElementsByTagName("book");
        for (i = 0; i < x.length; i++) {
            if (x[i].attributes["category"].value == "web") {
                var message = "";
                for (var j = 0; j < x[i].childNodes.length; j++) {
                    message += x[i].childNodes[j].nodeName + ':' + x[i].childNodes[j].textContent + '\n'
                }
                alert(message);
            }
        }
    }
</script>
