如果 DistanceMeters 在单独的行中，只需执行:

If DistanceMeters is in a separated line, just do:

awk '!/DistanceMeters/' file
<Trackpoint><Time>2014-02-12T18:18:49+11:00</Time>
<Position><LatitudeDegrees>35.209656</LatitudeDegrees><LongitudeDegrees>28.99924</LongitudeDegrees></Position>
<AltitudeMeters>586.99994</AltitudeMeters>
<Cadence>4</Cadence>
<Extensions><TPX xmlns="http://www.garmin.com/xmlschemas/ActivityExtension/v2" CadenceSensor="Bike"><Speed>0.043145742</Speed></TPX></Extensions></Trackpoint>

要将其从文本块内删除，您可以执行以下操作:

To remove it from inside a text block, you can do:

awk '{sub(/<DistanceMeters>[^>]*>/,x)}8' file

或者使用sed:

sed 's/<DistanceMeters>[^>]*>//g' file

这两者都不是贪婪的，因此它不会破坏多次出现 块的行，而不是使用贪婪的 .*

Both this is none greedy, so it will not destroy lines with multiple occurrence of <DistanceMeters> blocks, as oppose to use the greedy .*
