Question

Using php and Regex I am attempting to add <li>Valid in US</li> in the last UL after the last LI or to simply put after the last LI.

When debugging I cannot even get the contents of the last UL tag. This code brings up nothing when I do a var_dump (I have also tried preg_match_all with it):

if (preg_match("/((<ul>(.*?)<\/ul>/s){3})", $desc, $WARRANTY) == true)
var_dump($WARRANTY);

This is contents of $desc:

<h1>Stuff</h1>
<p>description</p>
<hr />
<strong>Features &amp; Benefits</strong>
<ul>
  <li>feat</li>
  <li>feat</li>
  <li>feat</li>
</ul>
<hr />
<strong>Specifications</strong>
<ul>
  <li>spec</li>
  <li>spec</li>
  <li>spec</li>
</ul>
<hr />
<strong>Warranty Information for a certain product</strong>
<ul>
  <li>3 Years Parts</li>
  <li>3 Years Labor</li>
</ul>
<div> <a href="/ahref" target="_blank">See more products from MFG </a></div>

Answer 1

If you want to match the <ul> tag with only 2 <li> tags in it, you can use this regex:

<ul>\s*(<li>[^<]+</li>\s*){2}</ul>

I can suggest another hacky way of adding the third li tag:

• use this regex:

  <ul>\s*(?:<li>[^<]+</li>\s*){2}(<)/ul>

• and replace the match in the first group with your <li></li> content followed by a < – because that’s what has been captured by the group (<)
