Topic: text position in the xml-file


I use the pro-version and its work fine.
But I have one wish - how can I centered the text in my xml.file for the menue ?
I know nothing about xml ...

This version will not work:

<NAV main_onColor="#FFFFFF" main_offColor="#FFFFFF" sub_onColor="#FFFFFF" sub_offColor="#CCCCCC" align="center" navWidth="800" x_padding="70" y_padding="4">

Best regards
