Help with setting XML data up in PHP

[gbice]

I have code that is reading server information and outputting data from a separate site. The below code is built to monitor several servers - and I only want to monitor ONE server. Let's assume the server name I wanted to monitor was "bobsled" - how would I pare down the below PHP info to read only information from the "bobsled" server?

Thanks! New to XML.

<?php

$insideitem = false;
$tag = &quot;&quot;;
$da_server = &quot;&quot;;
$da_population = &quot;&quot;;
$da_type =&quot;&quot;;
$da_status = &quot;&quot;;
$da_totalpop=0;

function startElement($parser, $tagName, $attrs) {
global $insideitem,$tag, $da_server, $da_type;
if ($insideitem) {
$tag = $tagName;
} elseif ($tagName == &quot;SERVER&quot
{

$insideitem = true;
while (list ($key, $val) = each ($attrs)) {
switch($key) {
case &quot;NAME&quot;: $da_server=$val;break;
case &quot;TYPE&quot;: $da_type=$val;break;
} // end case
} // end while
}

}

function characterData($parser, $data) {
global $insideitem, $tag, $da_server, $da_population, $da_type, $da_status,$da_totalpop;
if ($insideitem) {

switch ($tag) {
case &quot;POPULATION&quot;: $da_population .= $data; $da_totalpop += $data; break;
case &quot;STATUS&quot;: $da_status .= $data; break;
}
}
}

function endElement($parser, $tagName) {
global $insideitem, $tag, $da_server, $da_population, $da_type, $da_status;
if ($tagName == &quot;SERVER&quot {
print &quot;<TR><TD><b>$da_server</b>&quot;;
if ($da_type) { print &quot;(<i>$da_type</i>)&quot;; }
print &quot;</TD>&quot;;
print &quot;<TD>$da_status</TD>&quot;;
print &quot;<TD>$da_population</TD></TR>\n&quot;;

$da_server = &quot;&quot;;
$da_population = &quot;&quot;;
$da_status = &quot;&quot;;
$da_type = &quot;&quot;;
$insideitem = false;
}
}

// gotta have this for the php-NUKE block stuff to work
global $da_totalpop;

// Create an XML parser
$xml_parser = xml_parser_create();

// Set the functions to handle opening and closing tags
xml_set_element_handler($xml_parser, &quot;startElement&quot;, &quot;endElement&quot;

// Set the function to handle blocks of character data
xml_set_character_data_handler($xml_parser, &quot;characterData&quot;

// print &quot;<hr>\n&quot;;
print &quot;<TABLE BORDER=0 WIDTH=0%>\n<TR>\n&quot;;
print &quot;<TD><B>Server</B></TD><TD><B>Status</B></TD><TD><B>Users</B></TD>\n&quot;;
print &quot;</TR>\n&quot;;

// Open the XML file for reading
$fp = fopen(&quot;

http://www.camelotherald.com/xml/servers.xml&quot;,&quot;r&quot;)

or die(&quot;Error reading RSS data.&quot;

// Read the XML file 4KB at a time
while ($data = fread($fp, 4096))

// Parse each 4KB chunk with the XML parser created above
xml_parse($xml_parser, $data, feof($fp))
or die(sprintf(&quot;XML error: %s at line %d&quot;,
xml_error_string(xml_get_error_code($xml_parser)),
xml_get_current_line_number($xml_parser)));

// Close the XML filef
fclose($fp);

print &quot;<TR><TD>Total Users</TD><TD></TD><TD>$da_totalpop</TD></TR>\n&quot;;
print &quot;</TABLE>\n&quot;;

// free up used memory
xml_parser_free($xml_parser);
