XML Expat getting attribute names?

[alohaaaron]

Hi, I'm able to parse out XML elements and get the values of the attributes but not the names. For example I get ContactPricing and Price and the values 20 and 28 but I can't get the "email" or "phone".

$parser=xml_parser_create();
$element_attrs = array();

function start($parser,$element_name,$element_attrs) {
  global $element_attrs; //array of attributes
}

function stop($parser,$element_name) {
  echo "<br />";
}

function characterData($parser,$data) {
  global $element_attrs; //array of attributes
  echo $data;

  if (is_array($element_attrs)) {
      while(list($key,$val) = each($element_attrs)) {
        echo "<br>$key</br>"; //doesn't print out anything
        echo "<br>$val</br>"; //doesn't print out anything		
      }
  }
}


test data in xml file
<ContactPricing>
     <Price contactType="email">20</Price>
     <Price contactType="phone">28</Price>
</ContactPricing>

for those of you that might like to know how this was resolved, or how to use xml_parser without using the more usual xml_parse_into_struct, you need to set the default handler (or discrete character and element handlers) with the relevant xml_set_*_handler() functions and then create the handlers to deal with the data. Although the OP had half-hearted handlers in the original post, he had failed to tell php what the handlers actually were, and also had failed actually to parse the xml with xml_parse.

as (nearly) always, the php manual gives all the necessary information

however, this is not a sensible method of parsing xml data to extract variables. xml_parse_into_struct() is a more logical choice and if you are using a system that is less than a few years old (or if older then upgrade-blocked) then the simplexml extension is far more flexible.
