I get back, I need to change several of the HTML entities (><&), = I thought I
could stack the gsub! commands so they would be something like this:

my_string.gsub!(/>/, "<").gsub!(/</, ">)=

but I found that work, so for now I'm using:

my_string.gsub!(/>/, "<")
my_string.gsub!(/</, ">)

which works, but I'm sure is horribly inefficient. Is there a better wa= y to do
multiple global substitutions on a string?

Why would it be inefficient? It looks like the same thing to me= .
