The regular expression can be optimized a little more or maybe he could use a DOM library to parse the content.

Dom parsing in this case is unnecessary and much slower.

Feel free to propose an improvement of regular expressions.

Here are the expressions most used in the code:


$selectors = array(

'cls'=> array('prefix'=>".",
'regex_css'=>"/\.([a-z][a-z0-9\-_]*)[^a-z0-9\-_]/Usim",
'find_in_html'=>"/<[^>]*\s+class=['\"]\s*(?:([^'\"]+)\b\s*)*['\"]/ism"),

'id'=> array(
'prefix'=>"#",
'regex_css'=>"/#([a-z][a-z0-9\-_]*)[^a-z0-9\-_]/im",
'find_in_html'=>"/<[^>]*\s+id=['\"]([^'\"]+)['\"]/im"),

'tags'=> array(
'prefix'=>"",
'regex_css'=>"/^([^\.#@:][a-z0-9\-_]*)\b/im",
'find_in_html'=>"/<([a-z][^\s><]*)\b/i")

);
