如何解析xml響應

Question

我要求外部api，它給出以下響應。 它是XML格式。

這是方法，我如何使用

$('#trigger').click(function()
{
var token = '662d3330f192b4af77d5eef8de58f7e8c01a12a7';
var location = $('#Address').val();
var lat = $('#latitude').val();
var long = $('#longitude').val();
$.ajax({
    url: 'https://api.quickblox.com/data/Location',
    data: {
        token:'2100d8b55d4a389470b849de9378093dcda12903'
    },
    method: 'get',

    success: function(xml) {
        console.log(xml);
    }
});
});

這是我從服務器獲得的響應。

</data>

這是圖像的快照

如何從響應中獲取_id，created_at字段？

我在成功功能中嘗試過這樣

   success: function(xml) {
    console.log(xml);
    $(xml).filter('data').find('Location').each(function() 
    {
        var id = $(this).find('_id').text();
        var parentId = $(this).find('_parent_id').text();
        var createdAt = new Date($(this).find('created-at').text());
        var lat = parseFloat($(this).find('lat').text());
    });            
}

但是我什么也沒得到。 我怎樣才能做到這一點 ？

Answer 1

嘗試這個：

success: function(xml) {
    console.log(xml);
    var xmlDoc = $.parseXML(xml);
    $(xmlDoc).find("Location").each(function(idx, value) {
        var id = $(value).find("_id").text();
        var parentId = $(value).find('_parent_id').text();
        var createdAt = new Date(parseInt($(value).find('created-at').text()));
        var lat = parseFloat($(value).find('lat').text());
    });
}

最好在網絡上使用json

所以更換

 url: 'https://api.quickblox.com/data/Location'

同

 url: 'https://api.quickblox.com/data/Location.json'

可以毫無問題地訪問JSON
