Question

如何申请一个字符串正则表达式来从以下字符串

Is simply dummy text of the printing and typesetting industry. 
[video src="http://duel.evotechaustin.com/wp-content/uploads/2010/09/kramer.m4v"   width="480" height="360" id="b-test" class="player" ] 
Lorem Ipsum has been the industry's standard dummy text ever since the 1500s.

[video src="http://duel.evotechaustin.com/wp-content/uploads/2010/09/kramer.m4v" width="480" height="360" id="b-test" class="player" ] 

和DOM有不管怎么说得到相同的

Answer 1

preg_match("/\[video[^\]]+\]/i", $subject, $matches); 

$matches[0]包含

[video src="http://duel.evotechaustin.com/wp-content/uploads/2010/09/kramer.m4v" width="480" height="360" id="b-test" class="player"] 

Answer 2

这是一个短代码，你可以轻松地使用WordPress Shortcode API处理这些简码：

function video_shortcode($atts, $content = null) { 
    // do whatever you want to to 
} 
add_shortcode('video', 'video_shortcode'); 

在$atts数组，你将拥有所有从视频简码的属性列表：

array(
    "src" => "http://duel.evotechaustin.com/wp-content/uploads/2010/09/kramer.m4v", 
    "width" => "480", 
    "height" => "360", 
    "id" => "b-test", 
    "class" => "player" 
) 

Answer 3

使用子和的indexOf

的考试ple，

htmlString = document.getElementById('div').innerHtml(); 
startIndex = htmlString.indexOf("[video"); 
endIndex = htmlString.indexOf("]", startIndex); 
output = htmlString.substring(startIndex, endIndex);
