[LUG] VIM regexp problem

["Jon Haynes" <jon@xxxxxxxxxxxxxxxx>]

Trying to get VIM to globally search for a value at the start of a line
and then replace other values later on in the line with the initial value.

simple mockup e.g.
  <var id="FOO" r="R0" g="G5" b="R2">

I want each line like this to be converted to:
  <var id="FOO" r="FOO" g="G5" b="FOO">

I've got as far as:

  :%g/<var id="\([0-9A-Z]]*\)"/ s/R[0-9]/\1/g

...but it isn't working :-(

The problem is that \1 isn't getting the pattern from the first regular
expression.

Anybody know how to get the second command to pick up the regexp from the
first?

Thanks in advance.
Jon
