Shell Programming and Scripting

Hi

Code:

awk 'NR!=1 && !f{ if($0 ~ /point/)f=1;else if(x)print x;}{if ($0 ~ /\/point/){f=0;x="";}else x=$0}END{print x}' f=0 file

Guru.

Thanks Guru. I ran the awk command you suggested. It certainly removes what I wanted, but it also seems to be knocking out some other parts of the file, that are essential.

I tried presenting the problem at its simplest, so as not to burden you guys with unnecessary complications, but I see that it would be better if I explained the whole thing out.

The file that I am trying to edit is a KML file. It stores GPS coordinates and is interpreted by both Google Earth and Google Maps to draw maps. The file contains many folders, some called `Waypoints', some called `Tracks', some called `Points' etc. The `Points' folder contains extra waypoints that do not form a part of the track. These only clutter up the map, so I want to nuke the entire Points folder. Sadly, the declaration of folder names is slightly clumsy in KML. A file looks like this

Code:

<Folder>
  <name>Waypoints</name>
  # SOME ESSENTIAL STUFF
  # SOME ESSENTIAL STUFF
</Folder>
<Folder>
  <name>Tracks</name>
  # SOME ESSENTIAL STUFF
  # SOME ESSENTIAL STUFF
  <Folder>
    <name>Points</name>
    # JUNK
    # JUNK
    # JUNK
  </Folder>
  # SOME ESSENTIAL STUFF
</Folder>

What I need to remove is all instances of the Points folder (there are more than one), i.e. from <Folder> to </Folder> when the name tag value is `Points'. Another way to look at it would be to remove <Folder> to </Folder> when the 1st line after <Folder> reads <name>Points</name>.

I hope this helps

Thanks in advance!

No joy?

Hi,

try:

Code:

awk '/Folder>/{s=$0;t=getline;if ($0 ~ /Points/){f=0} else {if (t) print s;f=1}}f' file

Output:

Code:

<Folder>
  <name>Waypoints</name>
  # SOME ESSENTIAL STUFF
  # SOME ESSENTIAL STUFF
</Folder>
<Folder>
  <name>Tracks</name>
  # SOME ESSENTIAL STUFF
  # SOME ESSENTIAL STUFF
  </Folder>
  # SOME ESSENTIAL STUFF
  </Folder>

Hi Cristoph

That takes out what I need, but again, it seems to delete parts of the script that it isn't meant to. For some reason, it removes the first 100 odd lines of script as well. I would post the input and output files, but they're huge. Would it help if you showed you both?

Thanks
