"Could not find a suitable SAX2 parser" when i try parsing XML with XOM Tutorial

I'm trying to find a simple way to get XML content in my Android app. I gave XOM a try. Creating XML is no problem, but when i try to parse some... the emulator crashes with a force close. I have no idea where to look.

I have the internet permissions set in the manifest.

In debug/variables i can see "Could not find a suitable SAX2 parser" and in logcat something the same

One thing that i don't get is the warning when i add the jar to my buildpath. Don't know if something has to do with that:

[2011-07-22 14:38:13 - XOM] Dx warning: Ignoring InnerClasses attribute for an anonymous inner class
(nu.xom.Element$1) that doesn't come with an
associated EnclosingMethod attribute. This class was probably produced by a
compiler that did not target the modern .class file format. The recommended
solution is to recompile the class from source, using an up-to-date compiler
and without specifying any "-target" type options. The consequence of ignoring
this warning is that reflective operations on this class will incorrectl开发者_如何学Cy
indicate that it is *not* an inner class.

The code:

package com.xb.xomtest;

import java.io.IOException;

import nu.xom.Builder;
import nu.xom.Document;
import nu.xom.ParsingException;
import android.app.Activity;
import android.os.Bundle;

public class main extends Activity {

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        try {
              Builder parser = new Builder();
              Document doc = parser.build("http://www.cafeconleche.org/");
            }
            catch (ParsingException ex) {
              //System.err.println("Cafe con Leche is malformed today. How embarrassing!");
            }
            catch (IOException ex) {
              //System.err.println("Could not connect to Cafe con Leche. The site may be down.");
            }


    }
}

The xom jar doesn't, by itself, include everything you need - and apparently doesn't include the standard android parser in its list of suitable ones.

excerpt from http://www.xom.nu/install.xhtml:

"Java 1.3 and earlier do not have a built-in XML parser so in these environments you'll also need to install XOM's supporting libraries. These include xalan.jar, xercesImpl.jar, normalizer.jar, and xml-apis.jar, and are found in the lib directory. The versions shipped with XOM are quite a bit faster and less buggy than the ones bundled with the JDK, so you may well want to use them even in Java 1.4 and later. "

For basic parsing, adding xercesImpl.jar along with xom-1.2.7.jar appears to be sufficient - my code, which had the same problem (complaining about a missing sax2 parser) now parses the input OK.

I get the same Dx warning about inner classes, so that doesn't appear to be fatal :-).
