通过空格和括号将句子（HTML代码）拆分为单词

Question

例如，我想拆分以下HTML代码：

<a href="http://www.google.com">Google</a>

输出应该用空格和尖括号分隔

Array(
[0] => <
[1] => a
[2] => href="http://www.google.com"
[4] => >
[5] => Google
[6] => <
[7] => /a
[8] => >

Answer 1

不确定您要实现的目标，但是对于您的示例，您可以使用包含结果中捕获的分隔符部分的选项PREG_SPLIT_DELIM_CAPTURE：

$result = preg_split('/([<>])| /', $txt, -1, PREG_SPLIT_DELIM_CAPTURE | PREG_SPLIT_NO_EMPTY);

Answer 2

>>> '<a href="http://www.google.com">Google</a>'
    .match(/(<)(\w+)\s+(href=\"[\w\/:.]+\")\s*(>)(.*)?(<)(\/\w)(>)/)

 ["<a href="http://www.google.com">Google</a>" 
  ,"<", "a", "href="http://www.google.com"", ">", "Google", "<", "/a", ">"]
