title: How to check for and remove a newline (\n) in the first line of a text field in actionscript?
body: <p>In the script, sometimes a newline is added in the beginning of the text field (am using a textArea in adobe flex 3), and later on that newline might need to be removed (after other text has been added).  I was wondering how to check if there is a newline at the beginning of the text field and then how to remove it.  Thanks in advance. </p>
