Question

Suppose I have a long java String , I need to wrap all whitespaces (length >=2) with <pre></pre> tag… , How to achieve that ?

ex :

before :
String str = "<font color=\"#000000\">A B  C   D</font>"

after :
<font color=\"#000000\">A B<pre>  </pre>C<pre>   </pre>D</font>

Between A and B is one whitespace , and not wrapped.
Between B and C is two whitespaces , and it is wrapped.
Between C and D is three whitespaces , and it is wrapped,too.

How to achieve that in RegExp ? Thanks a lot !

Answer 1

How about a CSS solution using white-space:

white-space: pre

With this sequences of white space are not collapsed. So:

<font color="#000000" style="white-space:pre">A B  C   D</font>
