Question

他们是IndentingXMLStreamWriter.java的替代品我在某些时候总是遇到某种问题，虽然它在一段时间后消失但我无法编译。所以我想知道它们是否是另一种缩进手动解析的XML文件的方法

虽然当编译为netbeans模块的一部分时，错误消息略有不同......路径会被〜替换为任何想知道= p

只是要清楚一点，这将是我如何使用stax

import com.sun.xml.internal.txw2.output.IndentingXMLStreamWriter;

XMLStreamWriter xsw = XMLOutputFactory.newInstance().createXMLStreamWriter(new FileOutputStream(new File("Blah")));
xsw = new IndentingXMLStreamWriter(xsw);
xsw.writeStartDocument();
xsw.writeStartElement("map");
for (Map.Entry<String, Date> entry : map.entrySet()) {
     xsw.writeEmptyElement("entry1");
     xsw.writeAttribute("Name", entry.getKey());
     xsw.writeAttribute("date", sdf.format(entry.getValue()));
 }
 xsw.writeEndElement();
 xsw.writeEndDocument();
 xsw.close();

Answer 1

如果将XML解析为org.w3c.Document的实例（例如使用DocumentBuilderFactory），则可以尝试以下操作。

使用Apache Xerces：

Document doc = ...;
OutputFormat format = new OutputFormat(doc);
format.setIndenting(true);
format.setIndent(2);
XMLSerializer serializer = new XMLSerializer(out, format);
serializer.serialize(doc);

或使用标准的TransformerFactory：

Document doc = ...;
Transformer t = TransformerFactory.newInstance().newTransformer();
t.setOutputProperty(OutputKeys.INDENT, "yes");
t.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");
t.transform(new DOMSource(doc), new StreamResult(out));

Answer 2

你可以使用Saxon。在s9api界面中，您可以执行类似

的操作

Processor p = new Processor();
Serializer s = p.newSerializer(System.out);
s.setOutputProperty(Property.INDENT, "yes");
XMLStreamWriter w = s.getXMLStreamWriter();

然后你有一个实现XMLStreamWriter接口的缩进序列化程序，如果你想使用它们，可以使用更多的格式化选项。
