[PHP] Re: xml_set_character_data_handler logic
Cardinal from IRC answered my question. It turns out that when you indent
your childs with tabs, it sees those tabs as cdata of the root element. I
had the following XML file:
sampleDBName
sampleUser
localhost
The tabs in front of the child elements were treated as CDATA of the
root node.

[PHP] Re: [PHP-DEV] toString() in SimpleXML?
Hi Marcus,
Marcus Boerger wrote:
having a function __toString() would interfere with the mapping ideas of
SimpleXML. However it is there internally so you simply do one of the
following:
php -r '$x=SimpleXML_load_string("blablabla"); echo
$x, "\n"; var_dump((string)$x);'
I'm aware of that. But how would something like nodeValue() interfere
with the mapping ideas behind SimpleXML? IMHO, casts are not intuitive
in a development process, especially not when you need them as much as
you would in SimpleXML. Now it just feels like working around a problem
when coding.
further questions please to [EMAIL PROTECTED]

Hi,
I have a feature request. Maybe it would be a good idea to have a
toString() or perhaps nodeValue() method in SimpleXML's SimpleXMLElement
class? It might make it more obvious that the element is still a
SimpleXMLElement object when you want to actually use it (when you print
it, the value automagically casts to a string internally, so users might
think that it will be casted to a string when you directly access it
without a specified property/method, which is not the case). I know that
the docs say that you should cast it to a string when you want to do a
comparison, but apart from that just being an example, maybe my
suggestion is a more obvious one to notice?
regards,
Leendert
