麻烦遍历XML文件节点

Question

I have properly parsed one XML feed, and have inputted that data into a table on my site. However, I am dealing with a slightly more complicated feed, and am having trouble finding tree nodes.

XML Feed: http://xml.pinnaclesports.com/pinnaclefeed.aspx?sporttype=Football&sportsubtype=NFL

Declare variables:

$AwayLine = (string)$xml2->spread_visiting;  
$HomeLine = (string)$xml2->home_visiting;

From my understanding, the feed is broken down as(obviously, im wrong):

foreach ($xml2->event->period[0]->spread as $Spread) {  
    $AwayLine = $Spread->spread_visiting;   
    $HomeLine = $Spread->spread_home;  
}

Based on the XML path, every item is seen as an event. Every event has multiple periods. Every period has a spread. Every spread includes spread_visiting and spread_home. However, I only need the spreads in the first period, or period[0]

Any help would be greatly appreciated!

Answer 1

Both events and periods are missing from your statement, so it should be:

foreach ($xml2->events->event as $event) {
    foreach ($event->periods->period[0]->spread as $spread) {
    }
}

Not 100% sure about it, but you might be able to write this as well:

foreach ($xml2->events->event->periods->period[0]->spread as $spread) { }
