parsing entities

hello, I am parsing an xhtml template throught the php xml expat parser. But the problem is that it removes all entities from the xhtml template such as &nbsp; or &amp; (in href anchors attributes) The entities can't be handle with xml_set_default_handler because some entities are inside an attribute (title, href) and are then printed before the tag. How can I fix this? I don't understand how those other functions work: http://www.php.net/manual/en/function.xml-set-external-entity-ref-handler.php http://www.php.net/manual/en/function.xml-set-unparsed-entity-decl-handler.php Could it be the solution? Another problem is that it changes tags like <img /> by <img></img>. Is there a way to avoid this? + Cheers (PS - I am also curious about how the fuction xml_set_start_namespace_decl_handler() work. Does someone know some informations about?)
