[The Mog]

hi guys,

I guess its something small but i am overlooking something somewhere

 
<?php
 
if ($_GET['lat'] != "" && $_GET['lng'] != ""){
 $file = utf8_encode("http://ws.geonames.org/findNearbyPlaceName?lat=".$_GET['lat']."&lng=".$_GET['lng']."&style=full");
 $content = false;
 $tag = "";
 $name = "";
 $countryName = "";
 $adminName1 = "";
 function startElement($parser, $tagname, $attrs) {
    global $content, $tag, $name, $countryName, $adminName1;
    if ($content) {
      $tag = $tagname;
    } elseif ($tagname == "geonames") {
      $content = true;
    }
  }
  function endElement($parser, $tagname) {
      global $content, $tag, $name, $countryName, $adminName1;
      if ($tagname == "geonames") {
        // printf("<a href='%s'>%s</a>",trim($url),trim($name));
         print "Name: ".$name."<br>";
         print "Admin Name: ".$adminName1."<br>";
         print "Country: ".$countryName."<br>";
         $name = "";
         $countryName = "";
         $adminName1 = "";
         $content = false;
      }
  }
  function characterData($parser, $data) {
    global $content, $tag, $name, $countryName, $adminName1;
      if ($content) {
        switch ($tag) {
        case "name":
          $name .= $data;
          break;
        case "countryName":
          $countryName .= $data;
          break;
        case "adminName1":
          $adminName1 .= $data;
          break;
        }
      }
    }
  $xml_parser = xml_parser_create();
  xml_set_element_handler($xml_parser, "startElement", "endElement");
  xml_set_character_data_handler($xml_parser, "characterData");
  $fp = fopen($file,"r")or die("Cant open file");// The name and location of your XML file
  while ($data = fread($fp, 4096)) //4mb chunks recomended
    if(!(xml_parse($xml_parser, $data, feof($fp)))){
    die("Error on line " . xml_get_current_line_number($xml_parser));
    }
    fclose($fp);
    xml_parser_free($xml_parser);
 }
 ?>

Any help will be great

Thanks

Hi Guys,

I found the problem,

for some reason you have to use CAPS ??? Can someone please explain why to me?

 if ($_GET['lat'] != "" && $_GET['lng'] != ""){
 $file = utf8_encode("http://ws.geonames.org/findNearbyPlaceName?lat=".$_GET['lat']."&lng=".$_GET['lng']."&style=full");
 $content = false;
 $tag = "";
 $name = "";
 $countryName = "";
 $adminName1 = "";
 function startElement($parser, $tagname, $attrs) {
    global $content, $tag, $name, $countryName, $adminName1;
    if ($content) {
      $tag = $tagname;
    } elseif ($tagname == "GEONAMES") {
      $content = true;
    }
  }
  function endElement($parser, $tagname) {
      global $content, $tag, $name, $countryName, $adminName1;
      if ($tagname == "GEONAMES") {
        // printf("<a href='%s'>%s</a>",trim($url),trim($name));
         print "Name: ".$name."<br>";
         print "Admin Name: ".$adminName1."<br>";
         print "Country: ".$countryName."<br>";
         $name = "";
         $countryName = "";
         $adminName1 = "";
         $content = false;
      }
  }
  function characterData($parser, $data) {
    global $content, $tag, $name, $countryName, $adminName1;
      if ($content) {
        switch ($tag) {
        case "NAME":
          $name .= $data;
          break;
        case "COUNTRYNAME":
          $countryName .= $data;
          break;
        case "ADMINNAME1":
          $adminName1 .= $data;
          break;
        }
      }
    }
  $xml_parser = xml_parser_create();
  xml_set_element_handler($xml_parser, "startElement", "endElement");
  xml_set_character_data_handler($xml_parser, "characterData");
  $fp = fopen($file,"r")or die("Cant open file");// The name and location of your XML file
  while ($data = fread($fp, 4096)) //4mb chunks recomended
    if(!(xml_parse($xml_parser, $data, feof($fp)))){
    die("Error on line " . xml_get_current_line_number($xml_parser));
    }
    fclose($fp);
    xml_parser_free($xml_parser);
 }
 ?>

Hi,

I've not had much experience with XML, but with the XML I've seen, the tags are always in CAPS.

So, if PHP's string comparisons are case-sensitive, it's probably why you have to use CAPS for your tag name comparison.

Would be my guess
