If you grep for the line containing <lastmod> and exclude those lines from the stream, you can then pipe that to the next command.

Be sure to make a backup copy before you do any of this.

ummmmmm

....

grep -v <pattern> <filename> >> newfile.txt

?

so

grep -v lastmod originalfile.txt > newfile.txt

Once everything is gone that you don't want, maybe sed would work better for the substitution part?
