Today I upgraded to Ultra-Edit 12. Ultra-Edit is my favorite text editor. It features line numbering, find and replace using regular expressions, syntax highlighting, nine additional clipboards, word count, spell checking, hex editor, trailing space trim, and formatting to uppercase, lowercase, or capitalize.
As usual it is the regular expression find and replace that is the most useful. I can easily remove all the blank lines from my text. I can convert lines of text into a comma separated list or convert a comma separated list into lines of text. For XML I prefer to use an old version of XML Spy that can do some validation.
