您可以使用StAX（
javax.xml.stream）解析器并将
javax.xml.transform每个部分转换（）到DOM节点（
org.w3c.dom）：
import java.io.*;import javax.xml.stream.*;import javax.xml.transform.*;import javax.xml.transform.stax.StAXSource;import javax.xml.transform.dom.DOMResult;import org.w3c.dom.*public class Demo { public static void main(String[] args) throws Exception { XMLInputFactory xif = XMLInputFactory.newInstance(); XMLStreamReader xsr = xif.createXMLStreamReader(new FileReader("input.xml")); xsr.nextTag(); // Advance to statements element TransformerFactory tf = TransformerFactory.newInstance(); Transformer t = tf.newTransformer(); while(xsr.nextTag() == XMLStreamConstants.START_ELEMENT) { DOMResult result = new DOMResult(); t.transform(new StAXSource(xsr), result); Node domNode = result.getNode(); } }}另请参阅：
