Select and replace the first instance:

SEARCH: (?s)\A.*?<tr>\s*\K.*?(\s*</tr>)(?=$)
REPLACE BY: NEW CONTENT $1

or

SEARCH: (?s)\A.*?<tr>\s*\K.*?(\s*</tr>)
REPLACE BY: NEW CONTENT $1

Select and replace the last instance:

SEARCH: (?s)<tr>.*</tr>.*?<tr>\K.+?(?=</tr>.*?\z)
REPLACE BY: \r NEW CONTENS $1 \r

or

SEARCH: (?s)\A.*<tr>\K.+?(?=</tr>)
REPLACE BY: \r NEW CONTENS $1 \r
