sed: how to replace string by another line
hi experts,

i would like to do some html-file replacements and encounter the following problem: after cleaning up the file a bit i'd like to replace a regex with a reference and the content of another line. example:

Code:
/<title>\([^\-]*\) - Wikipedia<\/title>/

should be replaced by \1 (the title itself) PLUS underscore followed by the content of line lets say no. 5. so I guess it would similar to this:

Code:
s/<title>\([^\-]*\) - Wikipedia<\/title>/\1_*reference to line no. 5*/g

I'm sure this is not the solution but i don't know how to do it either. can anyone help?

thanks

chris

Code:
$ echo "/<title>\([^\-]*\) . Wikipedia<\/title>/" | awk '{print $0"\1_*reference to line no. 5*/g"}'
/<title>\([^\-]*\) . Wikipedia<\/title>/\1_*reference to line no. 5*/g

thanks for the quick reply. the problem here is that I would like to do the replacement as part of a sed script stored in a file. so I just use sed -f script.sed old.html > new.html. the file contains stuff like

Code:
/<!DOCTYPE html PUBLIC "-\/\/W3C\/\/DTD XHTML 1.0 Transitional\/\/EN"/,/<head>/d
s/	//g
s/<title>\([^\-]*\) - Wikipedia<\/title>/\1\t/g
/<meta http-equiv="Content-Type"/,/<!-- bodytext -->/d

is it also possible to add the replacement to such a sed script?

br
