импорт кмл с явой

3 голосов
/ 08 февраля 2012

Я пытаюсь импортировать MKL-файл с помощью jak, но получаю следующую ошибку:

javax.xml.bind.UnmarshalException: непредвиденный элемент (uri: "http://earth.google.com/kml/2.2", local:" kml ")Ожидаемые элементы ... а затем большой список

Кто-нибудь еще сталкивался с этой проблемой?

Это код: 

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());
        }

И этоФайл kml:

Вот мой быстрый и грязный путь:) 

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);
}

Я незнаком с Jak, но если вы используете OGC Schema , пространство имен будет другим. У вас есть 

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

Пространство имен OGC 

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

Схема расширения Google использует 

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

также. Используемое вами пространство имен использовалось Google до того, как KML был передан OGC в качестве открытого стандарта.

Пространство имен неверно, но если у вас есть 1700 файлов, и это единственная проблема, вы можете рассмотреть возможность использования формы Kml.unmarshal с двумя аргументами (File file, логическая проверка). 

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;
    }

Я также использовал следующий сценарий cheezy perl для исправления моих файлов. 

$ 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
