Xml/flash

i got this xml code from the portfolio tutorial :

[color=blue]<?xml version=“1.0” ?>
<portfolio>
<picture title = “work 1”
thumb = “portfolio_images/thumbs/work1.jpg”
description = “portfolio_text/work1.txt”
image = “portfolio_images/work1.jpg” />

<picture title = “work 2”
thumb = “portfolio_images/thumbs/work2.jpg”
description = “portfolio_text/work2.txt”
image = “portfolio_images/work2.jpg” />

<picture title = “work 3”
thumb = “portfolio_images/thumbs/work3.jpg”
description = “portfolio_text/work3.txt”
image = “portfolio_images/work3.jpg” />
</portfolio>[/color]
