RE: Remove blank lines

Thanks for replying. But it doesn't seem to work as expected. Either way, i 
will solve it otherwise, i will execute a script which will take care of it 
(all it takes is one line of code).

Thanks again!

I think that the following should do the trick:

            <replaceregexp flags="g" byline="false">
                <regexp pattern="\r\n[\s]*\r\n[\s]*\r\n"/>
                  <substitution expression="&#13;&#10;&#13;&#10;"/>
                  <fileset dir="${dist}">
                        <filename name="**/*.php"/>
                  </fileset>
            </replaceregexp>
Where "\r\n[\s]*\r\n[\s]*\r\n" means 2 blank lines and
"&#13;&#10;&#13;&#10;" means 1 blank line, so the maximum of blank lines
will be 1.

Subject: Remove blank lines
Hi,

I'm having troubles finding out how to actually remove blank lines.

I have a regular expression which will match all blank lines, but since
it
needs to be replaced with something, you get the problem ;)
            <replaceregexp flags="g" byline="true">
                <regexp pattern="^[\s]*$"/>
                  <substitution expression=""/>
                  <fileset dir="${dist}">
                        <filename name="**/*.php"/>
                  </fileset>
            </replaceregexp>
To be honest, what i would really like to achieve is to have it remove
blank lines only if there are two or more blanklines in a row, so it
still
leaves one blank line.
ie.

1. $foo = 'bar';
2. blank line
3. blank line
4. $user =& new User();
5. blank line
6. $user->doSomething();
would result in

1. $foo = 'bar';
2. blank line
3. $user =& new User();
4. blank line
5. $user->doSomething();
Thanks a lot in advance!

Regards,
J�rgen
