如何在XML中包含名稱空間時將PHP用於PHP？

我正在尋找一種方法來獲取以下XML文件中的kuler:swatchHexColor值。我嘗試了幾種方法，但沒有運氣。我在下面嘗試了這一點，但做得不好。如何在XML中包含名稱空間時將PHP用於PHP？

再次嘗試將hexColor值放入變量中。

$feed = simplexml_load_file('url'); 
$kuler = $feed->children('http://kuler.adobe.com/kuler/API/rss/'); 
foreach ($kuler->themeItem as $themeItem) { 
    echo $themeItem->swatch; 
}

這應該被標記爲[標籤：PHP]而不是[標籤：jquery] – Alexander

你說過你在使用jQuery，但是你正在顯示PHP代碼。 –

對不起，我的意思是PHP。很抱歉。全新的這東西。 – kangoroo

有兩種常見的方式做到這一點在PHP。首先，使用簡單的XML擴展（如你已經這樣做）：

$feed = simple_xml_load_file('url'); 
// resister the kuler namespace 
$feed->registerXpathNamespace('kuler', 'http://kuler.adobe.com/kuler/API/rss/'); 
// get elements regardless of their position in tree -> // 
$result = $feed->xpath('//kuler:swatchHexColor'); 

// iterate through the result set 
foreach ($result as $item) { 
    echo $item, PHP_EOL; 
}

您還可以使用DOM擴展：

$feed = new DOMDocument(); 
$feed->load('url'); 

// create an xpath selector for the document 
$selector = new DOMXPath($feed); 
// register the kuler namespace 
$selector->registerNamespace('kuler', 'http://kuler.adobe.com/kuler/API/rss/'); 

// get elements regardless of postion in tree -> // 
$result = $selector->query('//kuler:swatchHexColor'); 

// iterate trough the result set 
foreach ($result as $node) { 
    // do what you want with the node ... 
    echo $node->nodeValue, PHP_EOL; 
}
