getAttribute()

[Philipp L. <le...@hi...>]

I put my little own getAttribute() function in the class. Did I miss
something or is there really only getAttributes(), and if there's no
attribute of that kind available it causes an error? That were my experience
with v2.20. Well I use a DTD to my XML that even expands some attributes to
a value if none is given but I guess DTDs aren't parsed.

Another question, how can/ should I comment the class now that I did a
little change? I tried to scan the mozilla license for some information. I
hope it's not illegal to redistribute the class inside my package (it's not
the core, I just use it for the free QML-interpreter at
http://questml.com ).

My own function actually returns not null but an empty string if the
attribute is not found, which I think is not really standard but very nice
for my own purpoes. Now in case it's not a workaround for something that's
already in the class here goes my source (just as reference with no intend
to have it in any "official" version).

    function getAttribute($absoluteXPath, $attributeName)
    {
        $attributeValue = "";
        $attributes = $this->getAttributes($absoluteXPath);
        foreach ($attributes as $key => $value)
        {
            if ($key == $attributeName && $attributeValue == "")
                $attributeValue = $value;
        }

        return $attributeValue;
    }
