PHP的SimpleXML找到HTML标签的文本XML元素内

Question

如何在XML PHP变量设置为一切<STRONG>标签中所示：

<SAVED_EXPORT> 
    <metatag_description> 
    Some text here? The &lt;strong&gt; Cambro High-Impact 12" x 16" Dietary Tray&lt;/strong&gt; is the solution. Comprised of high-impact, ligh 
    </metatag_description> 
</SAVED_EXPORT> 

<? foreach($xml as $SAVED_EXPORT) { 

     $header = $SAVED_EXPORT->metadescription; 
     echo $header[0]; 
     } 
?> 

我希望它只是吐出：寒武高影响12" ×16" 膳食托盘，而不是所有的描述

Answer 1

尝试增加，而不是你的回音下面的表达式：

if (preg_match("/\&lt\;strong\&gt\;(.*?)\&lt\;\/strong\&gt\;/si", $header[0], $match) == true) 
{ 
    echo $match[1]; 
} 

Answer 2

使用strpos和substr：

$string = 'Some text here? The <strong> Cambro High-Impact 12" x 16" Dietary  Tray</strong> is the solution. Comprised of high-impact, ligh'; 

// Tag to look for 
$tag  = 'strong'; 
$start_tag = '<' . $tag . '>'; 
$end_tag = '</' . $tag . '>'; 

// Determine position of search pattern <strong> 
$begin = strpos($string, $start_tag); 
// Add the lenght of the tag string: 
$begin += strlen($start_tag); 
// Determine position of search pattern </strong> 
$end = strpos($string, $end_tag); 
// Calculate length: 
$length = $end - $begin; 

// echo the trimmed substring 
echo trim(substr($string, $begin, $length));
