Parsing XML problem: Unable to open file

[jjfletch]

I'm parsing an XML file and displaying the results, but I'm having problems open the xml url. I keep getting the error message:

failed to open stream: HTTP request failed! HTTP/1.0 400 Bad Request 

Here's the code:

$file="http://somexmlfile.com/";

$counter = 0;
$type = 0;
$tag = "";
$itemInfo = array();
$channelInfo = array();


function opening_element($xmlParser, $name, $attribute){
        global $tag, $type;
        $tag = $name;
        if($name == "RESULTLIST"){
                $type = 1;
        }
        else if($name == "RESULT"){
                $type = 2;
        }
}//end opening element

function c_data($xmlParser, $data){
        global $tag, $type, $channelInfo, $itemInfo, $counter;
        $data = trim(htmlspecialchars($data));

    if($tag == "TITLE" || $tag == "DESCRIPTION"){

            if($type == 1){
                    $channelInfo[strtolower($tag)] .= $data;
            }//end checking channel

            else if($type == 2){
                    $itemInfo[$counter][strtolower($tag)] .= $data;
            }//end checking for item
    }//end checking tag
}//end cdata funct


function closing_element($xmlParser, $name){
        global $tag, $type, $counter;
        $tag = "";

    if($name == "RESULT"){
            $type = 0;
            $counter++;
    }
    else if($name == "RESULTLIST"){
    $type = 0;
    }
}//end closing_element

$xmlParser = xml_parser_create();

xml_parser_set_option($xmlParser, XML_OPTION_CASE_FOLDING, TRUE);
xml_parser_set_option($xmlParser, XML_OPTION_SKIP_WHITE, TRUE);

xml_set_element_handler($xmlParser, "opening_element", "closing_element");
xml_set_character_data_handler($xmlParser, "c_data");

$fp = $file;

foreach($fp as $line){
if(!xml_parse($xmlParser, $line)){
die("Could not parse file.");
}
}

Can anyone shed some light?

You have to read from the file.

[jjfletch]

Actually, I did also try:

if(!($fp = fopen($file, "r"))) {
        die("could not open XML input");
} 

But, it yielded the same error.

[laserlight]

Try this script:

<?php
if(!($fp = fopen($file, "r"))) {
        die("could not open XML input");
}

foreach ($fp as $line) {
	echo $line;
}
?>

Do you see a problem?

If you dont, read the PHP Manual on [man]fopen/man and [man]xml_parse/man. You could also take a look at [man]file_get_contents/man.

Nope, I tried file_get_contents and variations of fopen, but it all yielded the same error. I know that the url is an xml file, so I don't understand why it's not working.

1. Test that you can open the file and print its contents without using any xml related function.
2. Test that you can parse the XML in a string without opening a file.
