NodeList在JAVA中返回带null的XML
我试图在以下步骤中解析XML，但返回的XML为空
步骤1：我得到以下XML字符串作为响应
<?xml version="1.0" encoding="UTF-8"?>

步骤2：我使用文档生成器构建XML
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
InputSource iSource = new InputSource(new StringReader(xmlResponse));
Document doc = dBuilder.parse(iSource);
doc.getDocumentElement().normalize();
步骤3：在执行下面的代码后，我获取节点并修改saml1p:Response的属性值，返回的XML为null
//Begin Issue seems to be in this block of code
NodeList samlResponse = doc.getElementsByTagName("saml1p:Response");
Element samlResponse = (Element) samlResponses.item(0);
samlResponse.setAttribute("InResponseTo", "_" + samlResponse.getAttribute("InResponseTo"));
//End Issue seems to be in this block of code
doc.getDocumentElement().normalize();
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
DOMSource source = new DOMSource(doc);
transformer.transform(source, new StreamResult(output));
上面的代码返回null，你知道为什么会出现这个问题吗
有趣的是，这段代码可以在生产环境中使用，但不能在我们的测试环境中使用
