Please advice a regular expression to find all string which are not ended with ".pdf". So, it should find stings "some string" and "some stringpdf", but not the strings like "some string.pdf"
Thanks, Aleksey Asiutin

If that's all you need, you can use a regexp to find .pdf-ended strings, and then reject them when they match, and accept the restLeo supports Monica Cellio– Leo supports Monica Cellio2013-02-07 14:32:06 +00:00Commented Feb 7, 2013 at 14:32

@Jack you're right, regexp is too mucch for such small task, thank you for pointing it out.Leo supports Monica Cellio– Leo supports Monica Cellio2013-02-07 18:51:34 +00:00Commented Feb 7, 2013 at 18:51

here's the regex
/^(?!.*\.pdf$).*/
example:
var r = /^(?!.*\.pdf$).*/;
r.test("some string"); //true
r.test("some stringpdf"); //true
r.test("some string.pdf"); //false
in actually, I recommend the suggestion from @Nannuo Lei.

If you are going to test individual string's you can use this regex
/^(?!.*\.pdf$).*$/
If there are multiple string's to be matched within the string,you can use
/(\s|^)(?![^\s]+\.pdf(\s|$))[^\s]+/
