There is likely a simpler way, but here is an easy three step process.
1. Text > Add/Remove Line Numbers... . Select “Insert”, check “Include space
after number”:
1 1001405001
2 0000(10)0000
3 001320000001
4 0(16)5000000
5 021(10)0000(11)
6 010101000
2. Text > Process Lines Containing... . Search string “\(\d+\)”. Check “Grep”,
“Copy to new document”:
2 0000(10)0000
4 0(16)5000000
5 021(10)0000(11)
3. Command-F (or Search > Find....). Search string “[ )]\d*\(?”. Replacement
string ” ” (a single space). Check “Grep”.Click “Replace All”.
2 10
4 16
5 10 11
In the result, each line contains a line number and one or more parenthesized
numbers, separated by spaces.
Explanation of the grep search: You want to keep the initial line number and
the parenthesized numbers, and remove everything else, replacing it by spaces.
The search string is a description of an “everything else”:
“[ )]”– An “everything else” begins with a space (which must be the space
following the line number, since those are the only spaces in the file) or the
closing parenthesis of a parenthesized number.
“\d+” — The string of contiguous digits following the space or closing
parenthesis are an “everything else” number.
“\(?” — The “everything else” number is either at the end of the line or it is
followed by the opening parenthesis of a parenthesized number. So if it is
followed by an opening parenthesis, then that is part of the “everything else”,
too.
