preg_match regex not quite working

[DH]

I need to parse some HTML tags and display the style classes, and have
it partly working, but need some regex / preg_match advise.

If the tag is <td class="red" colspan="1"> I can display "td.red"

If the tag is <td colspan="1" class="red"> my regex doesn't display the
desired "td.red" ... I can't figure out how to skip over colspan="1" if
the class doesn't immediately follow the HTML tag name.


$lines = explode("\n", $html);

foreach($lines as $line){

if(stristr($lin e, '<') && strstr($line, 'class=')){

if(preg_match("/<+([a-z]+) class=\"+([_a-z0-9-]+)\"/", $line,
$matches)){

echo
'<b>'.htmlspeci alchars($matche s[1].'.'.$matches[2]).'</b><br><br>'."\n ";

}

}

}


TIA.

Re: preg_match regex not quite working

Okay, i ran the script, and i noticed that it wasn't picking up any
spaces between the differen't rules, so it would pick up [space]class=
but it wont pick up [space]somthing[space]class, or maybe not even
just somthing[space]class,

when i modifed your regex code, i used the (.*) after the [a-z] so it
would take anything else in the code and put it into the matches. What
this means, is that it will match everything between the original tag
name and the class.

Ex:
<td colspan="1" rawr="woo" class="red">
will return
Array
(
[0] => <td colspan="1" rawr="woo" class="red"
[1] => td
[2] => colspan="1" rawr="woo"
[3] => red
)
(directly from php code)

and also, any thing after the class="red" does NOT match at all, so
your final result will be

echo
'<b>'.htmlspeci alchars($matche s[1].'.'.$matches[count($matches)-1]).'</b><br><br>'."\n ";
instead of just $matches[2];

Thanks for the reply. There are 80+ un-documented stylesheet classes in
a form generator named phpMyEdit, which I use extensively for admin
forms in web site projects.

Various styles appear in various page modes (add, change, copy, delete,
view, list, etc.). Every time I think I've tracked down all the
available style classes, something new is added, or else I find a
previously overlooked class.

In order to create a dynamic stylesheet (style.php) that evaluates the
current page mode (add, change, etc.) before defining colors and cell
borders, I need to make sure I've gathered ALL the relevant style classes.

In the next stable release of phpMyEdit (or currently in CVS) there will
be $_REQUEST vars that indicate with certainty the currently active page
mode (or which button was last clicked). It's likely there will also be
some new style classes, and I don't want to have to gather them
individually by hand (again).

IMHO, a better form generator does not exist, and the amount of brain
damage required to write something comparable to phpMyEdit is a waste of
time.

Thanks again for the regex help.
