Question

I got this problem, when edit my xml everything on a next line renders two breaklines

<![CDATA[Line one Line two Line three ]]> 

Renders in flash as

 Line One  Line Two  Line Three 

Now I researched this before and it had something to do with hidden breakline characters, Im using Flexbuilder and or Aptana to edit the xml, but how do I avoid having two breaklines when I want one.

Answer 1

Flash interprets both \r and \n as new line characters. If your input contains windows line endings (\r\n), then you see a blank line in the output.

To solve your problem, use the following regex to replace two consecutive occurrences of \r and \n with one before you output your data.

var newline:RegExp = /\r\n|\n\r/g; var input:String = 'your XML CDATA input'; var output:String = input.replace(newline, '\n'); 

Actually it is unlikely that \n\r ever occurs, but since we are already replacing, we can fix these invalid line endings as well.
