我想删除文章正文中带有大括号的任何段落。
例如，从这段内容中：
<p>While orthotic inserts are able to provide great support and pain relief, they aren’t quite as good as a specialty shoe. Remember that an ill-fitting insert can cause permanent damage and talk to a podiatrist about your foot pain for the best recommendation. Click here if you want to learn more about pain in the foot arch unrelated to plantar fasciitis.</p> <h2>Related Posts</h2> <h2>So What Are These Socks Really Good For?</h2> <h2>Are the bottom of your feet causing you problems?</h2> <h2>A PF Relief Guide</h2> <h2>What is Foot Reflexology & What is it Good For?</h2> <h2>Leave a Reply Cancel reply</h2> <p>Your email address will not be published. Required fields are marked *</p> <p>Name</p> <p>Email</p> <p>Website</p> <p>five − = 2 .hide-if-no-js { display: none !important; } </p><h2>Food For Thought January 2016</h2> <h2>Show Us Some Social Love!!</h2> <h2>Recent Posts</h2> <li> The Climate Pledge of Resistance</li> <li> Green Activism in Boulder, Colorado</li> <li> The Truth About Money and Happiness</li> <li> Why Is There So Much Skepticism About Climate Change?</li> <li> Which Device Would Work Best For You?</li>
我想删除这部分：
<p>five − = 2 .hide-if-no-js { display: none !important; } </p>
使用以下正则表达式：<p>.*?{.*?}.*?</p>
出于某种奇怪的原因，它删除了整篇文章，而不是包含大括号的这一段......
我用正则表达式代码做错了什么？谢谢！
懒惰/贪婪的量词并不总是按预期工作，而不是与不包括<的字符串匹配，这对我有用：<p>[^<]*{[^<]*</p>
试试这个：
var str = '<p>While orthotic inserts are able to provide great support and pain relief, they aren’t quite as good as a specialty shoe. Remember that an ill-fitting insert can cause permanent damage and talk to a podiatrist about your foot pain for the best recommendation. Click here if you want to learn more about pain in the foot arch unrelated to plantar fasciitis.</p> <h2>Related Posts</h2> <h2>So What Are These Socks Really Good For?</h2> <h2>Are the bottom of your feet causing you problems?</h2> <h2>A PF Relief Guide</h2> <h2>What is Foot Reflexology & What is it Good For?</h2> <h2>Leave a Reply Cancel reply</h2> <p>Your email address will not be published. Required fields are marked *</p> <p>Name</p> <p>Email</p> <p>Website</p> <p>five − = 2 .hide-if-no-js { display: none !important; } </p><h2>Food For Thought January 2016</h2> <h2>Show Us Some Social Love!!</h2> <h2>Recent Posts</h2> <li> The Climate Pledge of Resistance</li> <li> Green Activism in Boulder, Colorado</li> <li> The Truth About Money and Happiness</li> <li> Why Is There So Much Skepticism About Climate Change?</li> <li> Which Device Would Work Best For You?</li>';
var result = str.replace(/(<p>[^<]*{.*</p>)/, '');
console.log(result);正则表达式演示
我建议采用两步法（解析和分析文本节点）。
下面你会发现Python和PHP的例子（显然可以用于其他语言）：
