becksram123 · #1 (**permalink**) 06-30-2009

hi ,
i m having a html file and this file looks like this

Code:

 <ssl>
      <name>PIA</name>
      <enabled>true</enabled>
      <listen-port>39370</listen-port>
    </ssl>
    <log>
      <name>PIA</name>
    </log>
    <execute-queue>
      <name>weblogic.kernel.Default</name>
      <thread-count>50</thread-count>
    </execute-queue>
    <listen-port>37390</listen-port>

i need to search only listen -port and i need to take a value from here i.e 39370,37390

thanks in advance

with regards ,
ram

you can try something like this:

Code:

awk 'BEGIN { FS=" "; OFS=" " }
 
{
 
        if ( $0 ~ /<listen-port>/  &&  $0 ~ /<\/listen-port>/ ){
                # <listen-port>39370</listen-port>
                split($0,A,"\\076")
 
                # 39370</listen-port>
                split(A[2],LP,"\\074")
 
                listen_port=LP[1]
                printf("listen port is  %s\n",listen_port)
        }
 
}
 END {
 
 }' xmlfile

even below may help you some. But if it is well-formatted XML, suggest you t o use XML parser in Perl to handler this kind of issue.

Code:

sed -n '/<listen-port>/{s/<listen-port>\(.*\)<\/listen-port>/\1/;p;}' yourfile

You can try this in perl!

Code:

#!/usr/local/bin/perl
open( INPUT_FILE, "$ARGV[0]" ) || die "Cannot open input file $ARGV[0]\n";
while ($line = <INPUT_FILE>)
        {
                chop $line;
                @base=split(/\>/,$line);
                $base[0] =~ s/[\<]*//;
                $LengthOfTag=length($base[0]);
                $TotalLength=length($line);
                $FinalLength=$TotalLength - $LengthOfTag - $LengthOfTag - 5;
                $val=substr($line,$LengthOfTag+2,$FinalLength);
                if ( $base[0] eq "listen-port" )
                {
                        print "$val\n";
                }
        }
close(INPUT_FILE);

grep '<listen-port>' filename | cut -d '>' -f2 | cut -d '<' -f1

GNU awk

Code:

awk 'BEGIN{ RS="</listen-port>"}{gsub(/.*<listen-port>/,"")}1' file

Code:

sed -n 's/<listen-port>\([[:digit:]][^<]*\).*$/\1/p'
