regex 1

[w5000]

hello,
could someone please tell why the red regex does not work - I need to be sure line contains on first filed
if and then [numbers][whitespace]=[whitespace] and the rest not important here

$ echo "if1     sfdsf\nif12 = jfsflk\n   if4    =       sfsf"|awk '$1~/^if[0-9]+/'
if1     sfdsf
if12 = jfsflk
   if4    =       sfsf
$ echo "if1     sfdsf\nif12 = jfsflk\n   if4    =       sfsf"|awk '$1~/^if[0-9]+[COLOR=#EF2929][[:space:]]*=[[:space:]]*[/color]/'
$ echo "if1     sfdsf\nif12 = jfsflk\n   if4    =       sfsf"|awk '$1~/^if[0-9]+[COLOR=#EF2929][ \t]+=[ \t]+[/color]/'
$
