使用simplexml_load_file从XML提要中提取数据

Question

I'm trying to extract data from a XML feed using simplexml_load_file. This is what I have now:

    <?php 
        $anobii = simplexml_load_file('http://www.anobii.com/rss_shelf?s=01fe251a6c442bbf8a');
        foreach ($anobii->entry as $anobiiinfo):
            $title=$anobiiinfo->rss->channel->item->title;
            $desc=$anobiiinfo->rss->channel->item->description;       
            echo "<span> ",$title,"</span><br><span> ",$desc,"</span>";
        endforeach;
    ?>

The problem is that I don't know the right separators to tell the script the portions it needs to extract (rss->channel->item->title).

Answer 1

Yous should follow the xml tree structure to get the individual items.

<?php 
        $feedUrl = 'http://www.anobii.com/rss_shelf?s=01fe251a6c442bbf8a';
        $rawFeed = file_get_contents($feedUrl);
        $anobii = new SimpleXmlElement($rawFeed);

        foreach ($anobii->channel->item as $anobiiinfo):
            $title=$anobiiinfo->title;
            $desc=$anobiiinfo->description;       
            echo "<span> ",$title,"</span> <br/> <span> ",$desc,"</span>";
        endforeach;
    ?>
