The third parameter,
attribs
, contains an associative array with the element's attributes (if any).The keys of this array are the attribute names, the values are the attribute values.Attribute names are case-folded on the same criteria as element names.Attribute values are not case-folded. The original order of the attributes can be retrieved by walking throughattribs
