Question

I got dtd in file and I cant remove it. When i try to parse it in Java I get ‘Caused by: java.net.SocketException: Network is unreachable: connect’, because its remote dtd. can I disable somehow dtd checking?

You should be able to specify your own EntityResolver, or use specific features of your parser? See here for some approaches.

A more complete example:

<?xml version='1.0'?> <!DOCTYPE foo PUBLIC '//FOO//' 'foo.dtd'> <foo>     <bar>Value</bar> </foo> 

And xpath usage:

import java.io.File; import java.io.IOException; import java.io.StringReader;  import javax.xml.parsers.DocumentBuilder; import javax.xml.parsers.DocumentBuilderFactory; import javax.xml.xpath.XPath; import javax.xml.xpath.XPathFactory;  import org.w3c.dom.Document; import org.xml.sax.EntityResolver; import org.xml.sax.InputSource; import org.xml.sax.SAXException;  public class Main {      public static void main(String[] args) throws Exception {         DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();         DocumentBuilder builder = factory.newDocumentBuilder();          builder.setEntityResolver(new EntityResolver() {              @Override             public InputSource resolveEntity(String publicId, String systemId)                     throws SAXException, IOException {                 System.out.println('Ignoring ' + publicId + ', ' + systemId);                 return new InputSource(new StringReader(''));             }         });         Document document = builder.parse(new File('src/foo.xml'));         XPathFactory xpathFactory = XPathFactory.newInstance();         XPath xpath = xpathFactory.newXPath();         String content = xpath.evaluate('/foo/bar/text()', document                 .getDocumentElement());         System.out.println(content);     } } 

Hope this helps…
