Midterm

So, I did an NHL score retrieval system, using asterisk, PHP, XML, and Festival.

Here’s the code, using Shawn’s XML parser code:

#!/usr/local/bin/php -q

var $next;

function xml2array($xml_string)
{

xml_parser_set_option($Parser, XML_OPTION_CASE_FOLDING, 0);
xml_parser_set_option($Parser, XML_OPTION_SKIP_WHITE, 1);
xml_parse_into_struct($Parser, $xml_string, $Xml_Values);
xml_parser_free($Parser);
$XmlClass = array();
$LastObj = array();
$NowObj = &$XmlClass;

foreach($Xml_Values as $Xml_Key => $Xml_Value)
{
$Index = count($NowObj);
if ($Xml_Value[“type”] == “complete”)
{
$NowObj[$Index] = new Myxml;

if (isset($Xml_Value[“tag”]))
{
