Re: [PHP] DOM: browse childnodes but not recursively
28 maj 2005 kl. 19.32 skrev Jared Williams:
childNodes contains the textnodes too, in this case the whitespace
between each of .
So, to put it in short words; how do I do to browse the
content of the element id="5" withuot doing it recursively? I
want to receive a list when I call childNodes (or equivalent)
that gives me the elements with id 51-56, and a length of 6.
for($child = $elements->item(0)->firstChild; $child; $child =
$child->nextSibling)
if ($child->nodeType == XML_ELEMENT_NODE)
echo $child->getAttribute('id'), "\n";
Thanks for the answer!
It doesn't really work in my case, since I'm trying to create a
recursive function according the following:
1. I perform a search using xPath and get a search result as a
DOMNodeList.
2. This list I send to a function that takes it as input, and whats
function is to create a multidimensional array.
3. Foreach item in the list I check if it has any children.
4. If so, I do the recursive call, with the list of children as input.
So far so good, but when I come to the second loop, when the input is
the list from the childNodes, everything stops working...
Sincerely
Victor

childNodes contains the textnodes too, in this case the whitespace between each
of .
