If you see extra spacing between lines in the text content after loading and parsing XML document using AS3 in Flash, you have landed to the right blog post.
These extra line spcaes are caused due to \n newline characters and other whoite spaces present in the xml document. Good news is that you can easily remove these using the following snippet:
your_textfield.condenseWhite = true;
Make sure you add these lines after the action script code where xml data has already been loaded into the text fields. Condensing the “white space” removes all the extra line spacing.
Also, if your TextField uses Flash UIScrollbar Component, use the following snippet to readjust the scrollbars:
Hope that helps.
