[R] regexp,grep: capturing more than one substring

I would like to have a function that retrieve matching strings in the same way as with java.util.regex (java 1.4.2).
First of all: Is it possible to achiev this with grep(... perl=TRUE,value=TRUE )?
As I would call this function very often with large data, I'm reluctant to use Sjava for performance reasons.
Is this a wrong assumption that using Java directly would be slower or use more memory than to have a native R function?
Does someone already has a solution for this :)
