從XML文檔jQuery提取和顯示節點

我正在使用jQuery ajax調用WS-Trust服務來檢索SAML斷言。我的服務的響應包括完整的WS-Trust響應，並且我只需要doc中間的斷言。從XML文檔jQuery提取和顯示節點

的XML文檔是：

我有2個問題：

1 - 什麼是提取SAML2的最佳方式：斷言節點到一個新的XML對象？

2 - 然後將此對象轉換爲字符串以顯示在我的頁面主體中的最佳方式是什麼？

謝謝。

編輯，更新

TODO：在標籤

爲了使標籤的內容保留原始文檔大寫字母，也可以利用saml2\\:assertion元素outerHTML，saml2:Assertionsxml元素

的嘗試

html

<textarea></textarea>

// `ajax` method , options 
$.ajax() 
// `ajax` `.done()` , `success` callback 
.done(function(data, status, jqxhr) { 
     var xml = $(data.documentElement); 
     var assertion = xml 
     .children("ns3\\:requestedsecuritytoken") 
     .children("saml2\\:assertion"); 
     // raw xml , 
     // TODO: retain original document 
     // uppercase letters at tag 
     $("textarea").val(assertion[0].outerHTML); 
    });

我並不想這樣的作品，主要是因爲它迫使它的HTML，這使得一切小寫。另外，我需要嘗試並顯示原始XML，這只是顯示標籤的內容，而不是標籤本身。 – IanG 2014-09-05 06:12:26

查看更新後的帖子。謝謝 – guest271314 2014-09-05 06:40:13

謝謝，那釘了。 – IanG 2014-09-05 16:12:37
