Hi,

Please read example to get my requirement.

 String: "cancer of lung is example string to dig out the cancer."

I want to get cancer only in case when "cancer" is following "of lung".

is there any single regular expression which can do this.

Regards,

Ashwani
 

I got it.

i can use this

[a-zA-Z]+(?=( )of( )lung) 

 but take the below example

"lung cancer of lung is called as something of lung "

now my requirement is i want "cancer lung" and "something lung" through one regular expression.

any help.
