php - 如何解析博客rss文件

Question

我正在下載一些RSS格式的博客。這是一個例子：

<rss xmlns:opensearch="http://a9.com/-/spec/opensearch/1.1/"  xmlns:dc="http://purl.org/dc/elements/1.1/" version="2.0"> 
<channel> 
<title>

http://www.google.com/search?hl=en&q=john+doe+clippingsconverter&tbm=blg 
</link> 
<description>1 result</description> 
<opensearch:totalResults>1</opensearch:totalResults> 
<opensearch:startIndex>1</opensearch:startIndex> 
<opensearch:itemsPerPage>1</opensearch:itemsPerPage>

</item> 
</channel> 
</rss> 

我使用這個代碼：

$feed = file_get_contents($SearchURL); 
$xml = new SimpleXmlElement($feed); 

foreach ($xml->channel->item as $entry){ 
    echo $entry->title; 
    echo $entry->description; 
} 

我收到此錯誤信息：

Warning: SimpleXMLElement::__construct() [simplexmlelement.--construct]: Entity: line 21: parser error : Input is not proper UTF-8, indicate encoding ! 

我發現下載的飼料確實不這行在頂部，這可能會解釋錯誤。

<?xml version="1.0" encoding="UTF-8"?> 

感謝您的幫助。

Answer 1

檢查使用函數utf8_encode

$feed = utf8_encode(file_get_contents($SearchURL));
