xml中实体引用如何解析

Question

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE dmodule[
<!NOTATION svg PUBLIC "-//TEI//NOTATION W3C Scalable Vector Graphics Format//EN">
<!ENTITY AAA-DA10000-0-U8025-00514-A-04-1 SYSTEM "AAA-DA10000-0-U8025-00514-A-04-1.SVG" NDATA svg>
]>
 <dmodule>
<content>
<graphic  info="AAA-DA10000-0-U8025-00514-A-04-1"/>
</content>
</dmodule>

类似这种，xml中定义了实体引用，如何通过xmldocument或者别的方式读取出来。

Answer 1

 import java.io.File;

import javax.xml.parsers.DocumentBuilderFactory;

import org.w3c.dom.Comment;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.EntityReference;
import org.w3c.dom.Text;

public class Main {
  public static void main(String[] argv) throws Exception {
    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    factory.setValidating(true);

    factory.setExpandEntityReferences(false);
    Document doc = factory.newDocumentBuilder().parse(new File("filename")); //换成文件名

    Element root = doc.getDocumentElement();
    EntityReference eref = (EntityReference) root.getFirstChild();

    Comment comment = (Comment) eref.getFirstChild(); 

    Element elem = (Element) eref.getFirstChild().getNextSibling(); 

    Text text = (Text) eref.getLastChild(); 
  }
}
