这有点像我的XML:

<?xml version="1.0" encoding="UTF-8"?> 
<citizen> 
  <military> 
    <rank-points>62750</rank-points> 
    <stars>1</stars> 
    <total-damage>18243</total-damage> 
    <rank>Commander</rank> 
    <fight-count>0</fight-count> 
  </military> 
</citizen> 

现在,我想使用PHP导入标签"rank-points"中的内容

$rank = $xml->{'military'}->rank-points;

但是,因为XML标签的名称中带有" - ",所以它不起作用.结果始终为0.
