I have string with me :

Strings are: 

"Receiving datame2->$@<CTR>&CTData=<G><TT>d</TT>00<X>Approved</CTR>" **should match**

"Receiving datame2->$@<CTR>&CTData=<G><R>^@^<T>0Y<X>Approved</CTR>" **should not match**

I would like to write regex that do match the 

Receiving datame2(alltextin between)CTR(alldata in between)G(alldata in between)00(rest all data)

And .vice verse other then this should be rejected.

can i have to 2 Regular expression one for accepting and other one for rejecting the data. Other then this.

Try this for matching the first example in your question. The second example will be automatically rejected with the same regular expression.

Receiving datame2[^<]+<CTR>[^<]+<G>.+(?=00).+
