我一直在使用 Android 上的 Google“我的曲目”并将曲目导入 Google 地球。当我这样做时，我会在顶部看到时间栏，并且赛道会在你驾驶它时播放，就像你的赛道动画一样。我想删除该曲目的时间方面以及您在该曲目中所做的点的时间方面。
我进入 KML 文件，发现每个点都有一个时间戳。我一直在尝试首先使用以下方法删除负责实际轨道时间方面的元素：
xmlstarlet ed -d "kml/Document/Placemark/gx:MultiTrack/gx:Track/when" text.kml
至于地标，如果我能修正语法，我会假设这个过程是相似的。任何帮助将不胜感激。
Kml 结构如下，该元素是我要删除的元素，不确定 Google 地球是否会对那里没有元素或只是让它为空白感到满意。
xmlstarlet el -u text.kml
