Please tell me how to modify this regular expression.

Dear experts, please tell me how to write a regular expression. Grab a piece of content from a web page:

<code><div class="location fl">
        <span class="fl">商家地址：</span><span class="fl info-detail">北京市朝阳区亚运村阳光广场北门对面</span>
      </div></code>

The regex I wrote is:

<code>"<div class=\"location fl\">\s*?<span class=\"fl\">.*?</span><span class=\"fl info - detail\">(.*?)</span>\s*?</div>"</code>

It can pass on the regular expression tester, but the result cannot be obtained on PHP. How should it be modified?

Using xpath, it can be solved. "//div//span[contains(@class,'info-detail')]/text()[1]"
