PHP-DOMxml

Hi all, I hv spent too much time trying to solve this by myself and hope someone out there can help me out.. I am trying to use the DOM xml parser to parse my xml data.. The problem is that the parser reads only the parent and child elements but when the child nodes repeat themselves inside of child nodes, the parser simply refuses to read them.. Can anyone give me a suggestion as to how I can resolve this?? thnx in adv to all.. Sands
