字符串缺失分隔符上的单个捕获组的PCRE正则表达式

Question

I have html with this sort of node value:

80% Polyester 10% Cotton 10% Rayon

It can also be like these:

90% Cotton 10% Rayon

Or:

100% Cotton

EDIT -- ALSO the text to capture might be more than one word like:

90% Egyptian Cotton 10% Polyester

What I need to do in PHP is change it to be like:

<li>80% Polyester</li>
<li>10% Cotton</li>
<li>10% Rayon</li>

I'm not sure how to get the capture group quite right... maybe there needs to be two capture groups that can happen 1+ times?

preg_match('/<p>([1-9]?[0-9]?% [^\d<]+|^100% )+<\/p>/', '<p>80% Polyester 10% Cotton 10% Rayon</p>', $matches);

This only finds 1 match for: 10% Rayon... what am I doing wrong for it not to capture all 3 groups?

EDIT: PLEASE FORGET ABOUT THE HTML TAGS

I stripped the tags from the question because people can't get over the whole regex and html issue... think of this as just a data string please.

Answer 1

You may use this preg_replace:

$repl = preg_replace('/([\d.]+%\h*\pL+(?:\h+\pL+)*)\h*/', 
                     '<li>$1</li>
', $str);

RegEx Demo

([\d.]+%\h*\pL+(?:\h+\pL+)*)\h* matches and groups 1+ digits followed by % followed by 0+ spaces followed by 1+ letter and space characters.
