您已发布的XML是非常无效（&字符必须转义和标签必须被关闭），但这里是如何利用一些类似的XML使用SimpleXML。

$categories = simplexml_load_string(
    '<categories> 
     <category categoryid="1100" categoryname="Baby Clothing" categorylevel="1"/> 
     <category categoryid="1101" categoryname="Dresses" categorylevel="2"/> 
     <category categoryid="1102" categoryname="Trousers &amp; Jeans" categorylevel="2"/> 
    </categories>' 
); 

foreach ($categories->category as $category) 
{ 
    echo $category['categoryname'], "<br />\n"; 
}
