collecting values in array from tags ??

[PHPycho]

Hello forums.
Supppose i had following format in a string

$string = '<tag value="1">Name1</tag>
<tag value="2">Name2</tag>
:
:
<tag value="n">Namen</tag>';

I would like to collect those values and names in an array as

$array['name'] = array('Name1', 'Name2', .., 'Namen');
$array['value'] = array('1', '2', .., 'n');

Any suggestions and hints are warmly welcome.

If by tags you mean html form elements, you could use the same name attribute in multiple tags like this:

<tag name="somename[]" value="2">Name1</tag>
<tag name="somename[]" value="4">Name2</tag>

But of course this would give you a single array with key value pairs. You could then use a foreach loop to build a second array with the values of the original array as the keys of the new one.

You can use [man]preg_match_all()[/man] with a regex like

'/\<tag value="([^"]*)"\>([^<])*\<\/tag>/i'

I didn't check if it works, but this is what it is supposed to do:
- find string <tag value=" (< is because < is a special character)
- match character which isn't " 0 or more times
- then find "> (again > must be escaped)
- then match character which isn't < (this time < is inside character class, so it doesn't need to be ascaped - i think) 0 or more times
- and find closing </tag>
- i at the end means case-insensitive search and / something / are delimiters for this regex
