Pattern.DOTALL with String.replaceAll

Question

I have a multiline HTML document that I am trying to get some stuff from. I\'m using java\'s regex (I know - XML parsers bla bla bla, just bear with me here please :) ).

Answer 1

Attach (?s) to the front of your pattern :

input = input.replaceAll("(?s)<object classid=\"java:com\\.sun\\.java\\.help\\.impl\\.JHSecondaryViewer.*?object>", "buh bye!");

From the Javadoc:

Dotall mode can also be enabled via the embedded flag expression (?s). (The s is a mnemonic for "single-line" mode, which is what this is called in Perl.)

Other flags work this way as well

Special constructs (non-capturing)

...

(?idmsux-idmsux) Nothing, but turns match flags i d m s u x on - off

On a side note, if your goal is to remove unsafe objects from HTML from an untrusted source, please don't use regular expressions, and please don't blacklist tags.
