Problem with adding input to file ( using regex )
Problem: trying to read in the lines of the 1300 files i am looping through and parsing them with the regex i have - then saving the new lines into new files. When i try to add the lines into a Set, however, nothing is added. I'll attach a sample of one of the input files and the program as it is now, below. Any help would be greatly appreciated. Thanks.
Sample file:
癹/?惣M?t?C|怄紆鯅嶨垝鶨蔖疢2 0 0 3A D M . j p g? R A S T E R :W o r k s p a c e=L : \ a l b e r t a \ A r c G I S \ s l i d e s \ ;R a s t e r D a t a s e t=2 0 0 3A D M . j p g ; R a s t e rD a t a s e tR a s t e rB a n d 5Zq阊獋 繭? 4L : \ a l b e r t a \ A r c G I S \ s l i d e s \\R a s t e rW o r k s p a c e=L : \ a l b e r t a \ A r c G I S \ s l i d e s \ ;R a s t e rD a t aZ嶺浶?獆 繭?
