以下是一些代码，但它仅适用于您的任务：
public static void main(String[] args) throws ParserConfigurationException, SAXException, IOException,
TransformerConfigurationException, TransformerException {
DocumentBuilderFactory f = DocumentBuilderFactory.newInstance();
f.setValidating(false);
DocumentBuilder builder = f.newDocumentBuilder();
Document doc = builder.parse(new InputSource(new ByteArrayInputStream(xml.getBytes("utf-8"))));
Node root = doc.getFirstChild();
NodeList rootChilds = root.getChildNodes();
Node product = null;
// Searching "name" and "Product" tags
for (int i = 0, j = rootChilds.getLength(); i < j; i++) {
Node item = rootChilds.item(i);
if ("name".equals(item.getNodeName())) {
doc.renameNode(item, item.getNamespaceURI(), "PersonalDetails");
}
if ("Product".equals(item.getNodeName())) {
product = item;
break;
}
}
// Creating "actions" tag
Node actions = doc.createElement("actions");
product.appendChild(actions);
// Removing "BusinessInteractionType" tag and copy its value to "element" tag
for (int i = 0, j = product.getChildNodes().getLength(); i < j; i++) {
Node item = product.getChildNodes().item(i);
if (item != null && "BusinessInteractionType".equals(item.getNodeName())) {
String value = item.getFirstChild().getNextSibling().getTextContent();
Element element = doc.createElement("element");
element.appendChild(doc.createTextNode(value));
actions.appendChild(element);
product.removeChild(item);
--i;
}
}
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty(OutputKeys.ENCODING, "utf-8");
transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "no");
transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");
DOMSource domSource = new DOMSource(doc);
StreamResult streamResult = new StreamResult(new StringWriter());
transformer.transform(domSource, streamResult);
System.out.println(streamResult.getWriter().toString());
}

如果要将XML元素转换为不同的XML元素，则需要使用XSLT：
static void extractBusinessActions(String xml,
Result result)
throws TransformerException {
String xslt =
"<?xml version='1.0'?>\n" +
"<xsl:stylesheet" +
" xmlns:xsl='http://www.w3.org/1999/XSL/Transform'" +
" version='1.0'>\n" +
" <xsl:template match='//Product'>\n" +
" <actions>\n" +
" <xsl:for-each select='BusinessInteractionType/name'>\n" +
" <element><xsl:value-of select='.'/></element>\n" +
" </xsl:for-each>\n" +
" </actions>\n" +
" </xsl:template>\n" +
" <xsl:template match='text()|@*'/>\n" +
"</xsl:stylesheet>\n";
Transformer transformer =
TransformerFactory.newInstance().newTransformer(
new StreamSource(new StringReader(xslt)));
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.transform(new StreamSource(new StringReader(xml)), result);
}
