Change dynamic text position using xml file

Hi everyone, this is my first post and I’m still new to flash, but I take flash as my final task. I’m making something : input like text editor and picture editor using php, the output is swf, i’m using xml for the content. But i don’t understand how to change position dynamix text in flash with using xml.
here is my xml:

<?xml version=“1.0” encoding=“UTF-8” standalone=“yes”?>
<content>
<text>try1</text>
<posX>10</posX>
<posY>30</posY>
</content>

i can show the text but can’t use posX and posY for the dynamix position, dunno what syntax to use it.

here is my try, (fla, swf, and xml file)
sorry if my english is bad. thanks^^
