從kml文件中刪除<where> timestamp元素Google我的足跡

Question

我一直在玩Android上的Google「My Tracks」，並將曲目導入Google Earth。當我這樣做的時候，我會得到頂部的時間欄，軌道會在你開車的時候播放，就像你的軌道動畫一樣。我想刪除該曲目的時間方面以及您在該曲目期間製作的點的時間方面。

我進入KML文件，看到每個點都有時間戳。我一直在試圖消除負責首先使用的實際軌道的時間方面的元素：

xmlstarlet ed -d "kml/Document/Placemark/gx:MultiTrack/gx:Track/when" text.kml 

至於我假設的過程是相似的，如果我能得到固定的語法正確的地標。任何幫助將不勝感激。

Kml結構如下所示，元素是我想要移除的元素，並不完全確定Google地球是否會在那裏沒有元素，或者只是空白。

xmlstarlet el -u text.kml

這是默認名稱空間問題（請參閱5.1: Namespaces and default namspace）。

xmlstarlet ed -N k=http://www.opengis.net/kml/2.2 -d '/k:kml/k:Document/k:Placemark/gx:MultiTrack/gx:Track/k:when' text.kml 

在1.2.0之前的版本中，也需要-N gx=http://www.google.com/kml/ext/2.2。
