在PHP5中解析复杂的多个XML属性

Question

Hi guys first post on this site so excuse the formatting.

I'm new to xml parsing with php and well this xml feed has me stumped. I get using purely element based formats, but attributes this complex not so much. I tried to get the site to change to easier element based format but they're sticking with this format using attributes and I'm having a hard time pulling all the data in a listing/ranking style format particularly for each members' rankings and points.

example of xml file with only 2 members, but in reality there could 100s and 1000s depending on team id.

<sitemembers>
  <members>
    <member>
      <name>username</name>
      <team id="1200">team1 name</team>
      <rank>
        <today rank="34" points="613.30" results="70"/>
        <yesterday rank="33" points="614.20" results="70"/>
        <lastweek rank="60" points="541.70" results="68"/>
        <lastmonth rank="163" points="415.60" results="63"/>
      </rank>
      <awards>
        <global gold="0" silver="0" bronze="0" medal="1"/>
        <local gold="5" silver="2" bronze="0" medal="3"/>
      </awards>
    </member>
    <member>
      <name>username2</name>
      <team id="1200">team1 name</team>
      <rank>
        <today rank="46" points="577.80" results="178"/>
        <yesterday rank="45" points="580.00" results="178"/>
        <lastweek rank="40" points="586.60" results="178"/>
        <lastmonth rank="75" points="503.60" results="169"/>
      </rank>
      <awards>
        <global gold="0" silver="0" bronze="0" medal="0"/>
        <local gold="0" silver="2" bronze="2" medal="6"/>
      </awards>
    </member>
  </members>
</sitemembers>

and the output wanted in format

    Members ranking for team1 name (teamid: 1200)

    1. username
    Current rank: 34 : 613.30 pts (submissions: 70)
    Yesterday rank: 33 : 614.20 ps (submissions: 70)
    Last week rank: 60 : 541.70 pts (submissions: 68)
    Last month rank: 163 : 415.60 (submissions: 63)
    Global awards: 1 medals - [Gold: 0 Silver: 0 Bronze: 0]
    Local awards: 3 medals - [Gold: 5 Silver: 2 Bronze: 0]

    2. username2
    Current rank: 46 : 577.80 pts (submissions: 178)
    Yesterday rank: 45 : 580.00 ps (submissions: 178)
    Last week rank: 40 : 588.60 pts (submissions: 178)
    Last month rank: 75 : 503.60 (submissions: 169)
    Global awards: 0 medals - [Gold: 0 Silver: 0 Bronze: 0]
    Local awards: 6 medals - [Gold: 0 Silver: 2 Bronze: 2]

Any help is appreciated in steering me in the right direction. Thanks

Use SimpleXML

$sitemembers = simplexml_load_string($xml);

echo '<ol>';
foreach ($sitemembers->members->member as $member)
{
    $today = $member->rank->today;
    echo '<li>', $member->name, '<br />',
         'Current rank: ', $today['rank'], ' : ', $today['points'];
    // etc...
    echo '</li>';
}
echo '</ol>';
