It works for me...

irb(main):001:0> a = "<purpose>Reauthorization of collaborative weather 
modification
irb(main):002:0" research program within Department of Commerce/NOAA 
Weather modification
irb(main):003:0" research appropriations</purpose>
irb(main):004:0" "
=> "<purpose>Reauthorization of collaborative weather 
modification\nresearch program within Department of Commerce/NOAA 
Weather modification\nresearch appropriations</purpose>\n"
irb(main):005:0> a.gsub!(/<purpose>(.*)<\/purpose>/mi, 
'<row><entry><text><emph
irb(main):006:1' face="b">Purpose: </emph><entry><text>\1')
=> "<row><entry><text><emph\nface=\"b\">Purpose: 
</emph><entry><text>Reauthorization of collaborative weather 
modification\nresearch program within Department of Commerce/NOAA 
Weather modification\nresearch appropriations\n"
irb(main):007:0> a
=> "<row><entry><text><emph\nface=\"b\">Purpose: 
</emph><entry><text>Reauthorization of collaborative weather 
modification\nresearch program within Department of Commerce/NOAA 
Weather modification\nresearch appropriations\n"
