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>

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 $root = simplexml_load_string(' <root><child /></root> '); foreach ($root->child as $child) {var_dump($child);} ?> does not print anything while <?php $root = simplexml_load_string(' <root><child /> <child /></root> '); foreach ($root->child as $child) {var_dump($child);} ?> correctly prints object(simplexml_element)#2 (0) { } object(simplexml_element)#3 (0) { } -- Sebastian Bergmannhttp://sebastian-bergmann.de/ http://phpOpenTracker.de/Das Buch zu PHP 5: http://professionelle-softwareentwicklung-mit-php5.de/
