<p>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?</p>

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...
