Top Forums Shell Programming and Scripting Extract fragments from file Post 302897824 by black_fender on Wednesday 16th of April 2014 08:41:41 AM

I have a new issue on this topic.
I've settled to this awk expression :

Code:
targetFile=log.xml
targetItem="string 1 string2"
awk '/<mi>/ || s {s=s?s"\n"$0:$0} /<\/mi>/{if (s ~ Item) print s; s=""}' Item=$targetItem $targetFile

I have problems in declaring Item variable which takes its value from $targetItem when $targetItem contains spaces. I tried to declare targetItem like this :
Code:
targetItem="string1\ string2"

but it doesn't work.
The awk expression takes "string2" as a value for $targetFile ....


...Nevermind I forgot to use double quotes :
Code:
awk '/<mi>/ || s {s=s?s"\n"$0:$0} /<\/mi>/{if (s ~ Item) print s; s=""}' Item="$targetItem" $targetFile

Applogize for taking your time with this.

NAME

       Audio::MPD::Common::Item - a generic collection item

VERSION

       version 1.120881

SYNOPSIS

	   my $item = Audio::MPD::Common::Item->new( %params );

DESCRIPTION

       Audio::MPD::Common::Item is a virtual class representing a generic item of mpd's collection. It can be either a song, a directory or a
       playlist.

       Depending on the params given to "new", it will create and return an Audio::MPD::Common::Item::Song, an Audio::MPD::Common::Item::Directory
       or an Audio::MPD::Common::Playlist object. Currently, the discrimination is done on the existence of the "file" key of %params.

METHODS

   my $item = Audio::MPD::Common::Item->new( %params );
       Create and return either an Audio::MPD::Common::Item::Song, an Audio::MPD::Common::Item::Directory or an Audio::MPD::Common::Playlist
       object, depending on the existence of a key "file", "directory" or "playlist" (respectively).
