Careful! name="(.+?) (.+?)" will not do what you want, because there is
nothing keeping the (.+?) from matching past the first quote character.
You'll end up replacing all the spaces from the first occurence of name="
to the last occurence of ".
What you want is:
Find
name="([^"]*?) ([^"]*?)"
Replace
name="\1_\2"
Or even just:
Find (there's a trailing space)
name="([^"]*?)
Replace
name="\1_

Right, you need to do a loop within a loop, which you can't do with a
straightforward find & replace.
Here's one way to do it, in Perl:
#!perl -pi
s/name="([^"]*)"/ ($x = $1) =~ tr, ,_,; qq{name="$x"} /ge;
