Question

我正在尝试使用jak导入mkl文件，但是我收到以下错误：

javax.xml.bind.UnmarshalException：意外元素（uri：“http://earth.google.com/kml/2.2”，local：“kml”）。预期的要素是 ... 然后是一个大清单

有没有其他人遇到这个问题？

这是代码：

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());
        }

这是kml文件：

Answer 1

这是我快速而又肮脏的方式：）

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);
}

Answer 2

我对Jak不熟悉，但如果您使用OGC Schema，则名称空间不同。

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

OGC名称空间是

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

Google extension schema使用

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

也是。在将KML作为开放标准提供给OGC之前，Google使用了您正在使用的命名空间。

Answer 3

命名空间不正确，但如果您有1700个文件并且这是唯一的问题，您可以考虑简单地使用Kml.unmarshal的双参数形式（文件文件，布尔验证）。

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;
    }

我还使用了以下cheezy perl脚本来更正我的文件。

$ 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

用java导入kml
