Please edit your question to include sample input and output data. Do these strings occur on new lines, are there other delimeters? etc...

How do you define a "string"? Is "Ticket 1" one string or two? Are the quotes (") part of the string? Should we assume that a string is anything starting withTicket_until the next whitespace character? How aboutfooTicket_1? Should that be counted? Please edit your question and clarify.

You could use sed:
sed -i.BACKUP 's/"Ticket_.*"/"Ticket_Final"/g' <xml_file>
Explanation:
-i.BACKUP : It will substitute on the same file, but will keep a backup called xml_file.BACKUP, just in case it doesn't work as desired.
s/ORIGINAL_REGEXP/SUBSTITUTION/g : Substitutes (s) the ORIGINAL_REGEXP for SUBSTITUTION, for every occurence (g).
"Ticket_.*" : Anything like Ticket_... between quotation marks.

"Ticket_.*"will match the longest possible string between tso quotes, better to use"Ticket_[^"]*.

You are absolutely right, it will get every string till the final"it finds. But I think it is a must to still check for the first"it encounters, like"Ticket_[^"]*". But again it will accept anything just like"Ticket_"which I don't know if it is a requirement.

Would you mind explaining why? As far as I have used sed, which is very basic, thatgis there just in case there are several "Ticket_..." on the same line, otherwise just the first occurrence will be substituted.
– Isaac
Jul 28 '15 at 7:43
well, if there are several"Ticket_.*"matches on the same line,.*eats (at least) from the first through the last, and 1 is the most you can get out of it anyway.
