Read contents of an external XML page and then parse its contents

[jjfletch]

I have a URL that generates an XML page. I'm trying to read its contents and parse the information. But, I keep receiving these error messages:

Warning: filesize(): Stat failed for http://xmlurlgoeshere
(errno=2 - No such file or directory) in ... on line 100

Warning: fread(): Length parameter must be greater than 0. in ... on line 100

Here's the code:

function startElement($parser, $name, $attrs) {
        print "<B>$name => </B> ";
}

function endElement($parser, $name) {
        print "\n";
}

function characterData($parser, $value) {
        print "$value<BR>";
}

$simpleparser = xml_parser_create();
xml_set_element_handler($simpleparser, "startElement", "endElement");
xml_set_character_data_handler($simpleparser, "characterData");

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

while($data = fread($fp, filesize($file))) {
        if(!xml_parse($simpleparser, $data, feof($fp))) {
        die(xml_error_string(xml_get_error_code($simpleparser)));
        }
}

xml_parser_free($simpleparser);

[man]filesize[/man] does not work on http: URLs. So you'd need to specify something else in [man]fread[/man] (which, after all, is why it is in a loop and why xml_parse() takes an argument to say whether the file has ended or not).

Great, thank you much Weedpacket. I changed

while($data = fread($fp, filesize($file))) { 

to

while ($data = fread($fp, 4096)){ 

And it worked....

Now I just need to figure out how to format results... 🙂 Stay tuned for more questions!
