Question

I have the following java code:

DocumentBuilder db=DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document doc=db.parse(new File(\"/opt/myfile\         


        

Answer 1

Below code work for me, It ignore DTD

Imports:

import java.io.ByteArrayInputStream;
import java.io.File;
import java.io.IOException;

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;

import org.w3c.dom.Document;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
import org.xml.sax.EntityResolver;
import org.xml.sax.InputSource;
import org.xml.sax.SAXException;

Code :

File fileName = new File("XML File Path");
DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
EntityResolver resolver = new EntityResolver () {
public InputSource resolveEntity (String publicId, String systemId) {
String empty = "";
ByteArrayInputStream bais = new ByteArrayInputStream(empty.getBytes());
                    System.out.println("resolveEntity:" + publicId + "|" + systemId);
                    return new InputSource(bais);
                    }
                    };
documentBuilder.setEntityResolver(resolver); 
Document document = documentBuilder.parse(fileName);
