Thanks you rdrtx1,

With your command the half first part of the IP is replaced by 239.0.0.2 and the second part is 239.0.0.1

Is it possible to have a switching, for the Odd occurrences the IP 239.0.0.1 and for the Even occurrences the IP 238.0.0.2 ?

Regards,

It seems NR , do the modification in function of the line number and not the occurrence number.

It seems, In the first part the "grep <IP>" is on Odd line number and in the second part on Even

This Command works

Code:
awk 'BEGIN {a[1]="239.0.0.1"; a[0]="239.0.0.2" ; n=0} /<IP>/ {sub(">.*<",">" a[n%2] "<"); n++}; 1 ' tsp.xml

Thanks for your support
