Hello,
I use the following XML-file to store some useless facts I want to
display using PHP. I wrote some PHP code to generate HTML, because I do
not have any knowledge of stylesheets etc etc. The problem arises that
the php-function next_sibling from the DOMXML library doesn't seem to
do what it should. See the code later in this message.
Look at the lines below the comment line : # Cycle all item-elements
Why is the next sibling of my Item-node, a text-node? I use PHP 4.3.10.
By the way: why doesn't the domxml_open_file-function validate my XML
against the mentioned DTD-file?
Any help would be greatly appreciated.
