    Problem with domnode->next_sibling()

    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_fil e-function validate my XML
    against the mentioned DTD-file?

    Any help would be greatly appreciated.

      Why is the next sibling of my Item-node, a text-node? I use PHP 4.3.10.
      W/s are probably treates as anonymous text nodes. In this case, you'll
      need to strip them. Try calling your function with
      DOMXML_LOAD_DON T_KEEP_BLANKS.
      By the way: why doesn't the domxml_open_fil e-function validate my XML against the mentioned DTD-file?
      Try calling the function with DOMXML_LOAD_VAL IDATING.

      See PHP manual on how to use flags/modes.

          Whiskey,

          Great! That really worked for me (skipping blancs). Now I'll have a
          look at the validating part. Many thanks on giving more insight in this
          strange DOMXML behaviour.
