在java中编辑xml内容并将其作为字符串传递，最好使用节点

我有一个xml文档，它将用作模板

<?xml version="1.0" encoding="UTF-8" standalone="no"?><entry xmlns="http://www.w3.org/2005/Atom" xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"><content type="application/xml"><m:properties><d:AccountEnabled>true</d:AccountEnabled><d:DisplayName>SampleAppTestj5</d:DisplayName><d:MailNickname>saTestj5</d:MailNickname><d:Password>Qwerty1234</d:Password><d:UserPrincipalName>saTestj5@identropy.us</d:UserPrincipalName></m:properties></content></entry>

现在，我尝试编辑标记值，例如将“saTestj5”更改为“saTestj6”，然后转换整个xml并将其存储在xml中。有人能告诉我如何才能做到这一点吗？我被告知这可以通过使用“节点”来完成，这有可能吗

使用jaxb或sax解析器，通过使用getter方法将其转换为对象，然后更改对象并转换回xml

试一试

"InputStream is = getClass().getClassLoader().getResourceAsStream("/payLoadXML.xml");"

DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
        DocumentBuilder docBuilder = null;
        docBuilder = docFactory.newDocumentBuilder();

        Document doc = null;
        InputStream is = getClass().getClassLoader().getResourceAsStream("/payLoadXML.xml");
        doc = docBuilder.parse(is);

        Node staff = doc.getElementsByTagName("m:properties").item(0);

        Text givenNameValue = doc.createTextNode("abc");
        Element givenName = doc.createElement("d:GivenName");
        givenName.appendChild(givenNameValue);
       staff.appendChild(givenName);
    TransformerFactory transformerFactory = TransformerFactory.newInstance();
        Transformer transformer = null;
        transformer = transformerFactory.newTransformer();

        DOMSource source = new DOMSource(doc);
        StringWriter writer = new StringWriter();
        StreamResult result = new StreamResult(writer);

        transformer.transform(source, result);
