Question

以下是简单的html我想删除所有span标签，只是想要0.65的值。请有人帮我解决这个问题。

<span class="smw smw-inline smw-basic smw-ct-default smw-visible" data-symbol="GSD.V" data-type="inline" data-refresh-frequency="5" data-source="live"> 
<span class="smw-market-data-field smw-field-l1" data-field="l1">0.65</span> 
</span> 

Answer 1

您可以删除使用preg_replace('/<[^>]*>/', '', $content);

所有标签，你也可以删除使用这只span标签preg_replace('/<span[^>]+\>/i', '', $content);：

<?php 
$content = '<div><span class="smw smw-inline smw-basic smw-ct-default smw-visible" data-symbol="GSD.V" data-type="inline" data-refresh-frequency="5" data-source="live"> 
<span class="smw-market-data-field smw-field-l1" data-field="l1">0.65</span> 
</span></div>'; 

echo $string = preg_replace('/<[^>]*>/', '', $content); 

echo $new_string = preg_replace('/<span[^>]+\>/i', '', $content); 
?> 

Answer 2

我假设PHP和Perl此非常相似。 ...

s{\</?span[^>]*/?>}{}gism

Answer 3

您可以preg_replace和正则表达式做到这一点：

<?php 

$html = '<span class="smw smw-inline smw-basic smw-ct-default smw-visible" data-symbol="GSD.V" data-type="inline" data-refresh-frequency="5" data-source="live"> 
<span class="smw-market-data-field smw-field-l1" data-field="l1">0.65</span> 
</span>'; 

$without_span = $html; 
$without_span = preg_replace('#\n\r#', '', $without_span); 
$without_span = preg_replace('#\n#', '', $without_span); 

while(preg_match_all('#(<span.*?>)(.*?)(</span>)#', $without_span)) { 
    $without_span = preg_replace('#(<span.*?>)(.*?)(</span>)#', '$2', $without_span); 
} 

print_r($without_span); 

Answer 4

请尝试以下代码这一点。

$string = '<span class="smw smw-inline smw-basic smw-ct-default smw-visible" data-symbol="GSD.V" data-type="inline" data-refresh-frequency="5" data-source="live"> 
<span class="smw-market-data-field smw-field-l1" data-field="l1">0.65</span> 
</span>'; 

echo strip_tags($string);
