Hope this will help you ..

perl -nle 'print $1 if /<\/(.+?)\>/g' file.xml | wc -l

It's not perl script it is UNIX ibm aix.

Did you try to execute the above command?

xml doesn't have "columns" per se so I'm not really sure what you want. Could you show a more complete input file and what you're expecting to get from it?

try also:

awk '{c+=gsub("</mdm:attribute>","&")} END {print c}' file.xml

The grep counts lines with matches, not matches. Preprocess the file so every > becomes a line feed and grep for "</mdm:attribute$".
