how to match values of a line by values of another line? - regex

Question

I have a css file with the following structure:
#reg-1 {
top: 7.13%;
left: 7.36%;
height: 16.06%;
width: 85.14%;
}
#reg-1-magTarget {
top: 64.13%;
left: 36.36%;
height: 12.06%;
width: 99.14%;
}
#reg-2 {
top: 26.25%;
left: 21.49%;
height: 26.17%;
width: 55.19%;
}
#reg-2-magTarget {
top: 33.09%;
left: 17.27%;
height: 26.41%;
width: 45.04%;
}
And wanted to find a way to match the values of "#reg-1 {" by replacing the ones of "#reg-1-magTarget {" in notepad++ with regular expressions
to something like this:
#reg-1 {
top: 7.13%;
left: 7.36%;
height: 16.06%;
width: 85.14%;
}
#reg-1-magTarget {
top: 7.13%;
left: 7.36%;
height: 16.06%;
width: 85.14%;
}
#reg-2 {
top: 26.25%;
left: 21.49%;
height: 26.17%;
width: 55.19%;
}
#reg-2-magTarget {
top: 26.25%;
left: 21.49%;
height: 26.17%;
width: 55.19%;
}
I really don't know much about this but I was interested and I was trying combinations
I began to structure little by little the regex necessary to match it
try first
#reg-(\d) {
then I corrected it with this
#reg-(\d{1,2}) {
then i completed it
#reg-(\d{1,2}) {(\r\n)top:\s\d{1,2}(\r\n)left:\s\d{1,2}
then change to
#reg-(\d{1,9})-magTarget(\s){(\r\n)top:(\s)(\d{1,9})(\r\n)left:(\ s)(\d{1,9})
then search, I think it could work something like:
^(.+?)\h+:\h+"
by
$0$1
what makes this
Afghanistan: ''
be
Afghanistan : 'Afghanistan'

Answer 1

You can try (regex101):
(#reg-\d+)(.*?})\s+\1-magTarget.*?}
And for replacement
\1 \2\n\1-magTarget \2
Note: check Regular expression and . matches newline:

Answer 2

Find what:
(#reg-\d+)([^}]*})\R\K\1-magTarget[^}]*}
The pattern matches:
(#reg-\d+) Capture group 1, match #reg- and 1+ digits
([^}]*}) Capture group 2, Match 0+ times any char except } and then match }
\R\K Match a newline and then forget what is matched so far
\1-magTarget A backreference to the same what is matched in group 1, followed by matching -magTarget
[^}]*} Match 0+ times any char except } and then match }
Replace with:
\1-magTarget \2
See a regex101 demo.
But perhaps you can prevent the duplication of the css by writing the result as:
#reg-1, #reg-1-magTarget {
top: 7.13%;
left: 7.36%;
height: 16.06%;
width: 85.14%;
}
#reg-2, #reg-2-magTarget {
top: 26.25%;
left: 21.49%;
height: 26.17%;
width: 55.19%;
}
Find what:
(#reg-\d+)([^}]*})\R\1-magTarget[^}]*}
Replace with:
\1, \1-magTarget\2
