解析assets里的xml文件

比如解析如下文件

<?xml version="1.0" encoding="utf-8" ?>

<!-- n:Name f:filename d:description p:price-->

<product>

   <P n="Dracaena fragrans" f="fb001.png" d="" p="15"/>

   <P n="Epipremnum" f="fb002.png" d="" p="15"/>

   <P n="Pachira aquatica" f="fb003.png" d="" p="15"/>

   <P n="Chrysalidocarpus" f="fb004.png" d="" p="15"/>

   <P n="Polyscias" f="fb005.png" d="" p="15"/>

</product>
