来自Google地球的不同KML文件格式

Question

我正在从Google地球多边形创建KML文件。但是，创建的KML文件将以两种不同的格式显示。当一种类型出现在Google地球中时，将显示为链接。另一个将显示为纯文本。 显示为链接的KML格式如下：

<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://www.opengis.net/kml/2.2" xmlns:gx="http://www.google.com/kml/ext/2.2" xmlns:kml="http://www.opengis.net/kml/2.2" xmlns:atom="http://www.w3.org/2005/Atom">
<Placemark>
    <name>GHG</name>
    <ExtendedData>
        <Data name="stroke">
            <value>#555555</value>
        </Data>
        <Data name="stroke-width">
            <value>2</value>
        </Data>
        <Data name="stroke-opacity">
            <value>1</value>
        </Data>
        <Data name="fill">
            <value>#555555</value>
        </Data>
        <Data name="fill-opacity">
            <value>0.5</value>
        </Data>
        <Data name="Code">

        </Data>
    </ExtendedData>
    <Polygon>
        <outerBoundaryIs>
            <LinearRing>
                <coordinates>
                    35.54397940635681,33.17158011534832,0 35.54336249828339,33.16975707112739,0 35.54345905780792,33.16957296849484,0 35.54412424564362,33.17153521323674,0 35.54397940635681,33.17158011534832,0 
                </coordinates>
            </LinearRing>
        </outerBoundaryIs>
    </Polygon>
</Placemark>
</kml> 

以纯文本格式显示的图表的kml格式如下所示：

我需要解析这些kml文件，当格式标准化时，这是一个更容易的任务。我更喜欢第一种（GHG）格式。
