Question

可能重复：
foreach and simplexml

我的XML文档加载正确但我不确定如何创建一个简单的foreach我可以为Feed中给出的每个项目加载[PictureHref] [Title]和[PriceDisplay]

我在文档中找不到明确的例子。

目前我的PHP代码包含以下内容：

$mainUrl = 'http://api.trademe.co.nz/v1/Member/{id}/Listings/All.xml';
$xmlFeed = simplexml_load_file($mainUrl);

XML

<Listings xmlns="http://api.trademe.co.nz/v1" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">

        <Listing>

</Listings>

Answer 1

你需要的只是

$url = simplexml_load_file("__YOUR__URL___");
$listing = $url->List->Listing;

echo "<pre>";
echo $listing->PictureHref, PHP_EOL;
echo $listing->Title, PHP_EOL;
echo $listing->PriceDisplay, PHP_EOL;

Answer 2

虽然我建议使用DOMDocument而不是SimpleXML，但是在SimpleXML中你是如何做到这一点的：

$data = array();

foreach($xmlFeed->List as $item) {
    $data[] = array(
        (string) $item->Listing->PictureHref,
        (string) $item->Listing->Title,
        (string) $item->Listing->PriceDisplay
    );
}

你可以看到它（sorta，我必须改变一些事情）at CodePad

simpleXML创建foreach
