Hi Seders,

Given these lines in a file, say file.txt:
. . .
<tag: ptype>CC<tag: ptype> ( line a )
<tag: pdescr>International<tag: pdescr> ( line b )
<tag: pnum> <tag: pnum> ( line c )
. . .

I'd like to change the third line or line c to " <tag:XXXX> <tag:XXXX> " if and only if:

line a contains the word CC between the tags "<tag: ptype>"
there is a space character between the tags "<tag: pnum>" in line c.

Do you know how can i implement this using SED??? (or any other method)

Thanks

This is part of an XML file... I'm doing it on korn shell. thanks

Code:

awk '{ if( $0 ~ "^<tagpnum" ) { if ( $0 ~ ">CC<" ) { print "<tag:XXXX> <tag:XXXX>" } else { print } } else { print } }' file

Thanks,.. but i think this tests only line c (third line). I need to test the first line if it has a "CC" word on it..if it does...then i'll change the third line.

Code:

awk 'BEGIN{set=0} { if( $0 ~ "^<tagptype" ) { if ( $0 ~ ">CC<" ) { set=1; print } } else { if ($0 ~ "<tagpnum" ) { print "<tag:XXXX> <tag:XXXX>" } else { print } } }' file

As per your requirement, the above !


Can be optimized !

That was great! It worked! Thanks matrixmadhan!

I am just wondering..anyone know a sed version of this??? Please post it, i'll greatly appreciate it

Am afraid! That you didnt check the negative case,

Just now tested that and felt ashamed

Here is the proper code
for both the cases

Code:

awk 'BEGIN{set=0} { if( $0 ~ "^<tagptype" && $0 ~ ">CC<" ) { set=1; print } else { if ($0 ~ "<tagpnum" && set == 1 ) { print "<tag:XXXX> <tag:XXXX>" } else { print } }  }' file
