xml.getelement標記名稱無法正常工作

Question

我已經讀取了字符串中的所有xml內容。現在我正在解析該字符串。 我解析IAS的代碼如下：

parser=new DOMParser(); 
     xmlDoc=parser.parseFromString(output,"text/xml");//output is a string which contains xml 

     var region= xmlDoc.getElementsByTagName("Region"); 
     console.log("Region lenght"+region.length); 

有一個標籤名地區並有很多地區的在我的XML字符串。但我面臨的問題是這個xmlDoc.getelementBytagName只返回1個元素。

我的XML字符串的摘錄如下：

Answer 1

JS

parser=new DOMParser(); 
    xmlDoc=parser.parseFromString(output,"text/xml");//output is a string which contains xml 

    var region= xmlDoc.getElementsByTagName("Regions"); // Regions 
    console.log("Region length"+region.length);
