replace the n'th occurance in a file
Hi All,

How can i replace the n'th occurance in a file. ?
I have a property file like

EAR;_TrackingEAR;META-INF/application.xml;xml;context-root;1;valeur
EAR;_TrackingEAR;META-INF/application.xml;xml;context-root;2;valeur2
EAR;_TrackingEAR;META-INF/application.xml;xml;context-root;3;valeur2

i need to replace the <context-root> tag value in the application.xml file with new value valeur,valeur2 etc
1 means update the first occurance with valeur,
2 means second occurance with valeur2
3 for third occurance ...

How can i do this using sed or any other command ??

Thanks in advance

Subin

Code:
awk 'BEGIN{FS=OFS=";"}{$7="valeur"$6}1' file
