【问题描述】：

这可能是一个相对简单的问题，但我发现很难在 javascript 中解析我的特定 xml 对象。

我的 XML 看起来像这样

<ns2:GetItemResponse xmlns:ns2="urn:ebay:apis:eBLBaseComponents">
<Ack>Success</Ack>
<Build>E1125_INTL_API_19070421_R1</Build>
  <Item>
    <AutoPay>false</AutoPay>
    <BuyItNowPrice>0.0</BuyItNowPrice>
    <BuyerProtection>ItemIneligible</BuyerProtection>
    <Charity>
     <CharityID>1135</CharityID>
     <CharityName>The Humane Society of the United States</CharityName>
     <CharityNumber>1726</CharityNumber>

</Item>

</ns2:GetItemResponse>

我基本上想显示 Item 属性和 Charity 属性，但我发现很难理解我尝试过这样做的这些对象的子节点

  parser = new DOMParser();
                var obj = request.responseXML; 
                console.log(obj.getElementsByTagName("Item")[0]);
                xmlDoc = parser.parseFromString(request.responseText, "text/xml");
                //  panel.innerHTML += "<br> " + xmlDoc.getElementsByTagName("ItemId")[0].childNodes[0].nodeValue ;
                //console.log(xmlDoc.getElementsByTagName("Timestamp")[0].childNodes[0].nodeValue);
                console.log(xmlDoc.getElementsByTagName("Item")[0].childNodes);

所有帮助将不胜感激

这能回答你的问题吗？ Parse XML using JavaScript
@JamesWhiteley 很遗憾不是因为我总是收到错误“无法读取未定义的属性 'childNodes'”

const  docXML = `

const parser = new DOMParser()
  ,   xmlDoc = parser.parseFromString(docXML, "text/xml");


console.log( '1st CharityName = ', xmlDoc.querySelector('Item CharityName').textContent )

.as-console-wrapper { max-height: 100% !important; top: 0; }
