span标记中的preg_replace字符

Question

我有这样的字符串

<span style="font-size: 11pt; font-family: arial, helvetica, sans-serif;">I want replace this text to other text</span>
<span style="font-size: 18pt; font-family: arial, helvetica, sans-serif;">I want replace this text to other text</span>

我想使用PHP来实现它

    <span style="font-size: 11pt; font-family: arial, helvetica, sans-serif;">I want replace <a href="#">this text</a> to other text</span>
<span style="font-size: 18pt; font-family: arial, helvetica, sans-serif;">I want replace this text to other text</span>

我想只有文字有span样式字体大小：11pt替换 请帮帮我 感谢

根据你的意见，这个正则表达式将起作用

((?:.*?<span.*?style\s*=\s*"font-size\s*:\s*11pt[^>]*>))(.+?)(this text)(.*?(?<=<\/span>|$))
