◆ parseLinkAttrs()

Auth_OpenID_Parse::parseLinkAttrs (   $html)

Find all link tags in a string representing a HTML document and return a list of their attributes.

Todo:
This is quite ineffective and may fail with the default pcre.backtrack_limit of 100000 in PHP 5.2, if $html is big. It should rather use stripos (in PHP5) or strpos()+strtoupper() in PHP4 to manage this.
Parameters
string$htmlThe text to parse
Returns
array $list An array of arrays of attributes, one for each link tag
