How to call a class function from XML

am 03.10.2007 21:44:58 von Sandy.Pittendrigh

Let's say I have some XML that looks vaguely like:

I want to use the div line to call a class function, I.E. $this-
>mkNav();
without creating a hard-coded switch statement.

.....I'd like to say something like:
$cnt=0;
foreach ($xml->xpath("/template/div") as $adiv)
{
$this->divs[$cnt] = '

';
$myfunc = $adiv[@src];

$this->divs[$cnt] .= $myfunc;
.....or maybe something like:
eval ("$this->divs[$cnt] .= $myfunc");

$this->divs[$cnt] .= '

';
$cnt++;
}

....but of course none of the above works.
I don't want to have to remember to modify a switch
statement every time I add a new function to the class,
that might end up specified in the XML.

Hi

You could parse the xml file with php xslt processor. The Xslt
Processor class has
a function called registerPHPFunction(). You can find it in the doc!
The you you
could do something like this

// this line calls the php function
$this->divs[$cnt] = ;

Maybe this is a solution of your problem
