这是我的XML示例

      </ms:IN.NUMERICIVICI.2012>

    </gml:featureMember>

我必须在一些js变量中提取以下字段:

I have to extract in some js variables these fields:

• ms:nome
• ms:civico
• ms:istat
• ms:cap
• ms:comune

我还需要确保我的代码可以在IE，Firefox和Chrome上正常运行.

I need also to be sure that my code works right on IE, Firefox and Chrome.

我已经看到并尝试了一些在SO中找到的解决方案，但是没有用.

I've seen and tried several solutions that I've found here in SO but none work.

任何建议都非常感谢！

非常感谢您！

推荐答案

您可以像使用HTML一样使用jQuery和find()遍历XML元素.指定要选择的标记名称时，需要在选择器中省略名称空间前缀.

You can iterate through the XML elements using jQuery and find(), just like with HTML. When specifying tag names to select, you need to omit the namespace prefix in the selector.

var xmlText = $('#featureData').text(),
    $xmlData = $.parseXML(xmlText),
    $features = $('featureMember', $xmlData),
    extractedFeatures = [];

$features.each(function () {
    var $this = $(this),
        feature = {},
        items = [
            'nome',
            'civico',
            'istat',
            'cap',
            'comune'
        ],
        item;

    for (var i = 0; i < items.length; i++) {
        item = items[i];
        feature[item] = $this.find(item).text();
    }

    extractedFeatures.push(feature);
});

$('#output').text(JSON.stringify(extractedFeatures));
