通過使用Javascript或JQuery的元素值檢索XML節點

我正在處理一個問題，其中需要按特定屬性值篩選XML文檔並檢索所有匹配的節點。但是，我沒有得到理想的結果。通過使用Javascript或JQuery的元素值檢索XML節點

這是我用來遍歷兩個單獨的XML文檔的jQuery。爲了簡單起見，我正在對一個定義進行硬編碼。然後我需要通過definitionId過濾instanceData XML文檔並返回符合該條件的所有節點。

$(definitionData).find("Entity").each(function (index) { 
    var definitionId ="b1df0728-d761-e311-84c5-6c3be5a8bcd8"; 

    var instanceXmlRecords = $cm(instanceData).find("Entity").each(function() { 
    if ($(this).find("Id").text() == definitionId) { 
     return this; 
    } 
}); 
}

你可以補充足夠的重建中的問題你的問題？示例xml？你如何定義'cm'和'definitionData'？你想選擇什麼樣的XML？你使用的是什麼版本的jQuery？ –

Kevin，我想選擇符合條件的所有實體元素。我已將$ cm更改爲$以消除混淆。在這種情況下，我使用定義數據的唯一方法是檢索我需要用來過濾實例數據的正確ID。謝謝你快速的回覆。 –

你必須首先將XML字符串轉換爲XML文檔，那麼你可以通過標籤名稱的文件中搜索。離開命名空間。

http://jsfiddle.net/2D9MB/

var xml = $("#xml").text(); 
var xmlDoc = $.parseXML(xml); 
var definitionId ="b1df0728-d761-e311-84c5-6c3be5a8bcd8"; 
// find all entities that have an Id that contains the definitionId 
var entities = $(xmlDoc).find("Entity:has(Id:contains(" + definitionId + "))"); 
console.log(entities); // one entity

你甚至可以縮短最後一行是：

var entities = $(xmlDoc).find("Entity:contains(" + definitionId + ")");

此外，只需要清楚，您要過濾的是nodeText，而不是屬性值。 –

就是這樣。非常感謝！！！ –
