so how do you differ between the 'good' blank lines, which you want to keep, and the 'bad' ones, which you want removed?

Try this:

Code:
sed -e '/^$/d;' -e '/^[0-9]*$/{x;p;x;}' filename

You'll have to manually remove a blank line at the top of the file though.

It seems that you which to keep only the blank lines after the lines matching "textn":

script:
Code:
awk '! /^$/; /textn/ { print("") }' infile

input file:
Code:
$ cat infile
number

number:number ---> number:number

text1
.
textn

number

number:number--->number:number

text1
.
textn

number

number:number--->number:number

text1
.
textn

output:
Code:
number
number:number ---> number:number
text1
.
textn

number
number:number--->number:number
text1
.
textn

number
number:number--->number:number
text1
