The problem I'm having is that the XML data that comes back from the

parser to read the values using that format. (And I don't have
control over the host) As a first step, I just want to retrieve the
"eventname", "venuename", and "venuecity" data from within the
"result" tags at the bottom of the data.
I'm really hoping this is possible with PHP - - - can someone please
steer me in the right direction and tell my what I should change in
the below script? The $tag value is not getting a value string, due
to the XML-data....
Here's my present script:
<?php
$insideitem = false;
$tag = "";
$eventname = "";
$venuename = "";
$venuecity = "";
function startElement($parser, $name, $attrs) {
global $insideitem, $tag, $eventname, $venuename, $venuecity;
if ($insideitem) {
$tag = $name;
} elseif ($name == "RESULT") {
echo "found result";
$insideitem = true;
}
}
?>
You'll get these from the attributes array, which is an associative
array:
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
<http://www.php.net/manual/en/ref.xml.php#xml.case-folding> on the
same criteria as element names.Attribute values are /not/ case-folded.
From:
http://www.php.net/manual/en/function.xml-set-element-handler.php
So $venuecity - $attrs['venuecity'], etc.

OK. I was able to get hold of the file. Here's a small part of the
listing:
<f n="venueneighborhood">xphoenix;Paradise Valley;Greater Phoenix</f>
<f n="eventname">Remembering Amy</f>
<f n="eventsortname">REMEMBERING AMY</f>
<f n="eventid">3288076</f>
<f n="venueneighborhoodid">670;409;1957</f>
<f n="venuestate">AZ</f>
What you want to do here is to process the file, as you were doing,
checking for the attribute value you want, then capture
the element data once the attribute name is found. Here's a way to do
that (not tested but should work):
$eventname = "";
$venuename = "";
$venuecity = "";
$found = "";
function startElement($parser, $name, $attrs) {
global $eventname, $venuename, $venuecity;
// speed up the parsing since all the values have been found
if(!empty($eventname) && !empty($eventname) && !empty($eventname) {
return;
}
$found = $attrs['n'];
}
function characterData($parser, $data) {
global $eventname, $venuename, $venuecity;
// speed up the parsing since all the values have been found
if(!empty($eventname) && !empty($eventname) && !empty($eventname) {
return;
}
switch ($found) {
case 'eventname':
$eventname = $data;
break;
case 'venuename':
$venuename = $data;
break;
case 'venuecity':
$venuecity = $data;
break;
}
}
