需要幫助讀取XML @ JS

</vmext:Notification> 

System.log(myString) <-- the xml data from top 
var document = XMLManager.fromString(myString); 
var members = document.getElementsByTagName("vmext:EntityLink"); 
System.log(members.length) 

for (i = 0; i < members.length; i++){ 

System.log(members[i].attributes["ID"].value) 

}

我想從所有的vmext ID：EntityLink我剛剛返回NULL需要幫助讀取XML @ JS

如果你能幫助我將很樂意

你嘗試過這麼遠嗎？ – jediz

var document = XMLManager.fromString（myString）; var members = document.getElementsByTagName（「vmext：EntityLink」）。getAttribute（「id」）; SYSTEM.LOG（members.length）爲（I = 0; I

我得到這樣的過時間「無法調用」的Java腳本它在側面的VMware vrealize配器 VAR文件= XMLManager.fromString（MyString的）「空的」 –

它的一個小錯字。在下面的行中將您的ID替換爲id。

System.log(members[i].attributes["ID"].value)

而且您不需要在查找標記或元素中包含名稱空間。所以刪除vmext：從下面的行。

var members = document.getElementsByTagName("vmext:EntityLink");

這裏是工作的代碼，

<!DOCTYPE html> 
     <html> 
     <head> 
     <style> 
     .democlass { 
      color: red; 
     } 
     </style> 
     </head> 
     <body> 

     <h1 class="democlass">Hello World</h1> 

     <p>Click the button to display the value of the class attribute of the h1 element.</p> 

     <button onclick="myFunction()">Try it</button> 

     <p id="demo"></p> 

     <script> 
     function myFunction() { 
      var xml = '<?xml version="1.0" encoding="UTF-8"?>'

     +'</vmext:Notification>' 

      var document = parseXML(xml) 
      var members = 
        document.getElementsByTagName("vmext:EntityLink"); 
      console.log(members.length)

      } 
     } 
     function parseXML(val) { 
      if (document.implementation && 
    document.implementation.createDocument) { 
       xmlDoc = new DOMParser().parseFromString(val, 
    'text/xml'); 
      } 
      else if (window.ActiveXObject) { 
       xmlDoc = new ActiveXObject("Microsoft.XMLDOM"); 
       xmlDoc.loadXML(val); 
      } 
      else

       return null;

getAttributeNode; var members = document.getElementsByTagName（「vmext：EntityLink」）; SYSTEM.LOG（members.length）爲（I = 0; I

讀取屬性「attributes」以查找元素移除名稱空間「vmtext：」 – Yoganand
