Re: SimpleXML bug

We can (and I think we should) solve the attribute/child node ambiguity using the new array-syntax overloading, i.e., use $root['child'] for the attribute, and $root->child for nested elements. We should definitely stay away from having to use functions, either way. As for the array behavior, it's trickier, we need to think about it. Using an object that can cast itself to an array and implements the 'get' method (to fetch its value) may be the right answer. Zeev At 02:29 05/09/2003, Shane Caraveo wrote:

The problem is one of simplicity ;) I ran into the same problem a couple days ago. In the two examples, an array of element 'child' is expected. That array may be one or more elements. SimpleXML turns multiple children of the same element name into array's, but a single child is not. I'm not sure what the right answere is for it though, other than conditionaly checking for a single child. There's a part of me that thinks that children should be accessed via a function, but then you start getting dom-like: $root->childNodes()[0] and it always works. It also prevents problems with something like: <root child="test"> <child>abcd</child> </root> Shane Sterling Hughes wrote:

Zeev seems to be working on foreach and simplexml, but the above behaviour is the correct one. Why should the first loop? If I did: <?php foreach ("hello" as $world) {

        var_dump($world);

} ?> what would i get? -Sterling On Thu, 2003-09-04 at 18:24, Sebastian Bergmann wrote:

The following script <?php $root = simplexml_load_string(' <root>

     <child />
