Function get_elements_by_tagname() is only defined for the DocumentRoot-Element rather than for any DocumentElement.

if you want to search for tagnames with namespaces, do it the following way:

(it's a work around, not a really proper solution..)



$dom = domxml_open_mem($xmlval);

$ctx=xpath_new_context($dom); 

$ctx->xpath_register_ns("yns","http://your.name.space/uri");

$nodes = $dom->get_elements_by_tagname("yns:tagname",$ctx);
