java - Regex that matches a string and not a word -

i'd see internal libraries used in java project searching through code for

import com.mycompany.someproject.path.classname; 

let's project's title 'myproject'. regex match lines begin with

import com.mycompany. 

and exclude:

myproject.path... 

matched lines be:

import com.mycompany.tool.path.someclass; import com.mycompany.sallysproject.path.someotherclass; 

and exclude internal project imports:

import com.mycompany.myproject.* 

this should work:

import com\.mycompany\.(?!myproject\.).* 

explanation:

import com\.mycompany\. - line must start import com.mycompany.. pretty self-explanatory; note need escape periods -- \. -- match periods, , not "any character".

(?!myproject\.) - called "negative lookahead". overall match succeed if pattern inside parentheses (except ?!) not match.

.* - after import com.mycompany. (except myproject.) matched.
