Question

I’ve very little Java experience. I’m trying to force a document to be read as UTF-8, but have come stuck trying to hook the InputStream reader to the document builder.

Here’s what I have so far:

import javax.xml.xpath.*;
import javax.xml.parsers.*;
import org.w3c.dom.*;


if( pathToFile == null ) throw new Exception("You must supply a pathToFile parameter");

DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();

InputStreamReader in = new InputStreamReader( new FileInputStream( pathToFile ), "utf-8" );

BufferedReader reader = new BufferedReader ( new InputStreamReader ( in ) );

Element records = builder.parse(reader).getDocumentElement();

Be grateful if someone can provide me with some pointers

Answer 1

Assuming this is Groovy, you can rid yourself of a lot of the Java cruft:

Not tried it, but:

if( pathToFile == null ) throw new Exception("You must supply a pathToFile parameter");

Element records = new File( pathToFile ).withReader( "utf-8" ) { r ->
  DocumentBuilderFactory.newInstance().newDocumentBuilder().with { b ->
    b.parse( new InputSource( r ) ).documentElement
  }
}

should work…
