Subject: Editing a text file and then replacing existing file

I have a script that I use to find text in a file and then delete the
line(s) the text is on. That part works. What I have been unsuccessfully
trying to do is take the new text and overwrite the existing file that I
did the search and delete on. Here is my existing code that finds the
lines and deletes them:

path='c:\ruby192\my_projects\IIS_Logs\ex11012607.log'
search_text = %r{/memberinfo/downline/tree/can.asp}
search_text2 = %r{/memberinfo/downline/tree/disto.asp}
search_text3 = %r{/styles/default.css}
search_text4 = %r{/scripts/generalscript.js}
search_text5 = %r{/memberinfo/downline/tree/upl.asp}
search_text6 = %r{/scripts/wz_jsgraphics.js}
search_text7 = %r{/memberinfo/downline/tree/disfo2.asp}
search_text8 = %r{/styles/png.htc}
File.open(path, 'a+') do |file|
  file.each_line do |line|
      puts(line) unless line =~ search_text ||
  puts(line) unless line =~ search_text2 ||
      puts(line) unless line =~ search_text3 ||
      puts(line) unless line =~ search_text4 ||
      puts(line) unless line =~ search_text5 ||
      puts(line) unless line =~ search_text6 ||
      puts(line) unless line =~ search_text7 ||
      puts(line) unless line =~ search_text8
   end
file.write(line)
file.close
end
