How can I remove junk characters with regex? -


i have web application reads contents of web page , parses sentences using nlp algorithm. have been using regex split contents single sentences , parsing them.

i remove characters  sentences. these characters, imagine, because of html encoding.

i cannot use regex [^\w\d]+ or variations because need punctuations intact. of course add individual exceptions each of punctuation [^\w\d\.,:]+ , on, if there easier way this, character class knows a... funny character?

any appreciated. thanks.

edit: app built php , using simple file_get_contents() fetch html data site , reading contents inside <p> tags.

this mentioned in comments @thegreatco able create character class of "special" characters. can use hex code values create range in character class. special character on ascii 127 this.

[\x80-\xfe]

that match basic characters. reference sake, here's list of ascii character table hex codes.

this page discusses different ways can reference special characters in regex.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
