利用jQuery中的filter来过滤重复结构的xml数据

 

 

<?xml version="1.0" encoding="utf-8" ?>
<bookstore>
    <book>
        <title>Rain</title>
        <year>2010</year>
        <author>Martin</author>
    </book>
    <book>
        <title>Cloud</title>
        <year>2009</year>
        <author>Robert</author>
    </book>
    <book>
        <title>River</title>
        <year>2007</year>
        <author>Fred</author>
    </book>
</bookstore>

引入jQuery如下：

<script type="text/javascript" src="Scripts/jquery-1.4.1-vsdoc.js"></script>
<script type="text/javascript" src="Scripts/test.js"></script>

 

test.js的代码如下：

$(document).ready(function () {
    $.get("xmlData/Categories.xml", function (xml) {
                   $(xml).find("book").filter(
                    function (index) {
                        return "Rain" == $(this).find("title").text();
                    }
                   ).each(
                    function (index) {
                        alert($(this).find("author").text());
                            });
    });
});

输出结果：Martin
