I'm trying to write PHP code that will not only parse the XML but also
allow me to sort the parsed information by the values parsed.
Current code
==========
class RSSParser {
var $insideitem = false;
var $tag = "";
var $ServerName = "";
var $ServerStatus = "";
var $ServerType = "";
var $ServerPopulation = "";
function startElement($parser, $tagName, $attrs) {
if ($this->insideitem) {
$this->tag = $tagName;
} elseif ($tagName == "SERVER") {
$this->insideitem = true;
while (list ($key, $val) = each($attrs)) {
switch ($key) {
case "NAME":
$this->ServerName .= $val;
break;
case "TYPE":
$this->ServerType .= $val;
break;
}
}
}
}
function endElement($parser, $tagName) {
if ($tagName == "SERVER") {
printf("<tr>\n");
if ($this->ServerType) {
printf("<td>%s <i>(%s)</i></td>\n", $this->ServerName,
$this->ServerType);
} else {
printf("<td>%s</td>\n", $this->ServerName);
}
if ($this->ServerPopulation > 0) {
printf("<td>%s</td>\n", $this->ServerPopulation);
} else {
printf("<td>%s</td>\n", $this->ServerStatus);
}
printf("</tr>\n");
$this->ServerName = "";
$this->ServerType = "";
$this->ServerPopulation = "";
$this->ServerStatus = "";
$this->insideitem = false;
}
}
function serverData($parser, $data) {
if ($this->insideitem) {
switch ($this->tag) {
case "POPULATION":
$this->ServerPopulation .= $data;
break;
case "STATUS":
$this->ServerStatus .= $data;
break;
}
}
}
}
$xml_parser = xml_parser_create();
$rss_parser = new RSSParser();
xml_set_object($xml_parser,&$rss_parser);
xml_set_element_handler($xml_parser, "startElement", "endElement");
xml_set_character_data_handler($xml_parser, "serverData");
$fp = fopen("http://www.camelotherald.com/xml/servers.xml","r
<http://www.camelotherald.com/xml/servers.xml> ")
or die("Error reading RSS data.");
while ($data = fread($fp, 4096))
xml_parse($xml_parser, $data, feof($fp))
or die(sprintf("XML error: %s at line %d",
xml_error_string(xml_get_error_code($xml_parser)),
xml_get_current_line_number($xml_parser)));
fclose($fp);
xml_parser_free($xml_parser);
============
I've reviewed many online and book references and none have been helpful
in helping me to determine the way(s) in which I could do such a sort
from the parse code I have found to work very well. I have tried
looking for a way to also append multiple XML RSS files in one (all
sharing the same structure) into one and then sort according by a value
there. I am new to PHP and XML.
Any help and references would be greatly appreciated.
