我没有解析xml文档的经验,所以请耐心等待。在过去的几天里,我正在努力解析下面给出的xml示例!

在搜索互联网并阅读其他评论后,我得出结论,最好的办法是使用$ parseXML作为我处理的xml类型。

我验证了xml并使用了以下代码,但我一直得到无效的xml! 我的目标是获取属于一个<dict>的所有字符串值,并在<tr> 中使用它们。所以,如果专家帮我解决这个破碎的代码,我感激不尽。

这是我想将键值放在div中的方式:

var div = "<tr id=\""+i+"\">\n" +
"<td>"+i+"</td>\n" +
"<td><img src=\""+ categoryIcon +"\" height=\"42\" width=\"42\"></td>\n" +
"<td>\n" +
"<a href=\"javascript:doit('id=" + id + "&name=" + name + "&category=" + category + "&categoryIcon=" + categoryIcon + "','"+ country +"')\" onclick=\"selectLink(this);\">" + name + "</a><br> \n" +
"<br></td></tr>\n\n";

$("#myDiv").append(div);

javascript:

<html>
<head>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>
<script>
function myfunction(){
alert("me here");

var xml='<?xml version="1.0" encoding="UTF-8"?> <dict><key>ItemLists</key> <array><dict><key>id</key> <string>1</string> <key>name</key> <string>fruits</string> <key>category</key> <string>US Fruits</string> <key>categoryIcon</key> <string>http://www.somsite.com/categories/1.jpg</string> <key>country</key> <string>US</string> </dict> <dict><key>id</key> <string>2</string> <key>name</key> <string>Vegetable</string> <key>category</key> <string>Eu Vegetable</string> <key>categoryIcon</key> <string>http://www.somsite.com/categories/2.jpg</string> <key>country</key> <string>EU</string> </dict> </array> </dict>';
    xmlDoc = $.parseXML( xml ),
    $xml = $( xmlDoc ); 




$($xml).each(function(){

//alert($(this).find("dict>string").text());
//alert($(this).find("dict>key").text());
alert($(this).find("dict>categoryIcon>string").text());
});

};
</script>
</head>
<body>
<button onclick="myfunction()">parse</button> 
</body>
</html>

解析xml:

<?xml version="1.0" encoding="UTF-8"?>
<dict><key>ItemLists</key>
<array><dict><key>id</key>
<string>1</string>
<key>name</key>
<string>fruits</string>
<key>category</key>
<string>US Fruits</string>
<key>categoryIcon</key>
<string>http://www.somsite.com/categories/1.jpg</string>
<key>country</key>
<string>US</string>
</dict>

<dict><key>id</key>
<string>2</string>
<key>name</key>
<string>Vegetable</string>
<key>category</key>
<string>Eu Vegetable</string>
<key>categoryIcon</key>
<string>http://www.somsite.com/categories/2.jpg</string>
<key>country</key>
<string>EU</string>
</dict>

</array>
</dict>

    <script>
    function myfunction() {
        alert("me here");
        var xml = '<?xml version="1.0" encoding="UTF-8"?> <dict><key>ItemLists</key> <array><dict><key>id</key> <string>1</string> <key>name</key> <string>fruits</string> <key>category</key> <string>US Fruits</string> <key>categoryIcon</key> <string>http://www.somsite.com/categories/1.jpg</string> <key>country</key> <string>US</string> </dict> <dict><key>id</key> <string>2</string> <key>name</key> <string>Vegetable</string> <key>category</key> <string>Eu Vegetable</string> <key>categoryIcon</key> <string>http://www.somsite.com/categories/2.jpg</string> <key>country</key> <string>EU</string> </dict> </array> </dict>';
        xmlDoc = $.parseXML(xml),
        $xml = $(xmlDoc);

        $.each($xml.find('dict string'), function () {
            console.info($(this).text());
        });
    }
    </script>

或者您也可以在each声明$xml.find('dict>array dict string')

中执行此操作
