Removing and copying in shellscript
Hi,
I need to edit an xml file as such
Code:
<B="A"><![C]]></B>

so that the output is
Code:
<A><![C]]></A>

This is a massive xml file and the A B and C are always different however the output should always be the same.

Does anyone know any solution to this please?

thanks in advance

Hi,

I don't know if it will work with more complex files. Your example seems to simple, but give it a try:
Code:
$ cat infile
<B="A"><![C]]></B>
$ cat script.pl
use warnings;
use strict;

while ( <> ) {
        chomp;
        s#^[^"]+"([^"]+)">(<!\[[^]]+\]\]>).*$#<$1>$2</$1>#;
        printf "%s\n", $_;
}
$ perl script.pl infile
<A><![C]]></A>

Regards,
Birei

Code:
echo '<B="A"><![C]]></B>' | sed 's/<.="\(.\)">\(.*\)<.*/<\1>\2<\1>/g'

Like Birei said, will fail for complex patterns!
