Extract colored text from pattern

[azure_glass]

Hi there is a way to extract text from line to a var?

example:

[color= red]big ogre [/color] smashes [color= blue]tiny elf [/color] , with wooden club hinting his head.

pattern: (^(.*) (smashes|wounding) (.*)\.$)

Magic Code

My code: echo(matches[3] .. " ".. matches[4] .." ".. (matches[5]))

output:
[color= red]big ogre [/color] smashes [color= blue]tiny elf [/color]
