This should be a simple question, but I cannot find the answer. I need is to replace my Regex Match with blank space. What is the Syntax for this? Here is my Expression:

Matcher alphaSourceMatch = Pattern.compile('(?mi)<\\/?\\w*\\b[^>]*>').matcher(alphaSource);

I would simply like to replace the pattern with ' '.

  • Do you have an example of the text that this pattern is used against? Maybe a before & after (as you would expect it)...

  • Its extremely long and cryptic. It is an HTML email. I know that this matcher works, it's just a matter now of replacing the matches with blank space...how is that written? @MarkPond Sep 18, 2015 at 17:02
  • @MarkPond Essentially it just removes the content of all tags in an HTML email...leaving me with the plain text Sep 18, 2015 at 17:07

You just need to append the .replaceAll(' ') method to your Matcher instance to replace every match with a space.

Matcher alphaSourceMatch = Pattern.compile('(?mi)<\\/?\\w*\\b[^>]*>').matcher(alphaSource);
String replacedText = alphaSourceMatch.replaceAll(' ');

Docs: Matcher.replaceAll(string)

  • Thank you! Straightforward enough. I will give it a try. Sep 18, 2015 at 17:09
  • Updated my example, since replaceAll returns a string.
