import kml with java

I'm trying to import a mkl file with jak but i get the following error:

javax.xml.bind.UnmarshalException: unexpected element (uri:"http://earth.google.com/kml/2.2", local:"kml"). Expected elements are ... and then a big list

Does anyone else run into this problem?

This is the code:

final Kml kml = Kml.unmarshal(new File("../data/Eemskanaal.kml"));
        final Placemark placemark = (Placemark) kml.getFeature();
        Point point = (Point) placemark.getGeometry();
        List<Coordinate> coordinates = point.getCoordinates();
        for (Coordinate coordinate : coordinates) {
            System.out.println(coordinate.getLatitude());
            System.out.println(coordinate.getLongitude());
            System.out.println(coordinate.getAltitude());
        }

And this is the kml file:

<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://earth.google.com/kml/2.2">

Here is my quick and dirty way :)

public static Kml getKml(InputStream is) throws Exception {
    String str = IOUtils.toString( is );
    IOUtils.closeQuietly( is );
    str = StringUtils.replace( str, "xmlns=\"http://earth.google.com/kml/2.2\"", "xmlns=\"http://www.opengis.net/kml/2.2\" xmlns:gx=\"http://www.google.com/kml/ext/2.2\"" );
    ByteArrayInputStream bais = new ByteArrayInputStream( str.getBytes( "UTF-8" ) );
    return Kml.unmarshal(bais);
}

The namespace is incorrect, but if you have 1700 files and this is the only problem, you might consider simply using the two-argument form of Kml.unmarshal(File file, boolean validate).

final Kml kml = loadXMLFile("../data/Eemskanaal.kml");
private static Kml loadXMLFile(String path) {
        Kml kml = null;
        try {
            kml = Kml.unmarshal(path);
        } catch (RuntimeException ex) {
            kml = Kml.unmarshal(new File(path), false);
        }
        return kml;
    }

I've also used the following cheezy perl script to correct my files.

$ cat ~/bin/fixxmlns
#!/usr/bin/perl

for (@ARGV) {

    open (FH,"<$_");
    open (NFH,">$_.x");

    $look = 1;
    while ($r = <FH>) {
        if ($look && $r =~ /earth.google.com/) {
            $r = qq{<kml xmlns="http://www.opengis.net/kml/2.2" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:gx="http://www.google.com/kml/ext/2.2">\n};
            $look = 0;
            }
        print NFH $r;
    }
    close (NFH);
    close (FH);
    rename("$_", "$_.orig");
    rename("$_.x", "$_");
}
$ fixxmlns *.kml
$ find parentdir -name "*.kml" -print0 | xargs -0 fixxmlns

I am unfamiliar with Jak, but if you're using the OGC Schema, the namespace is different. You have 

http://earth.google.com/kml/2.2

The OGC namespace is

http://www.opengis.net/kml/2.2

The Google extension schema uses

http://www.google.com/kml/ext/2.2

as well. The namespace you're using was used by Google before KML was given to the OGC as an open standard.
