i found a more primitive fsockopen technique but then i found out it was a
problem with my isp restricting curl and fsockopen and i was getting a
permission denied error
here is the fsockopen technique that i was able to use at an isp that didn;t
support cURL
i also created a simple parser here without using xml_parser but it doesn;lt
do any error checking for input or output
but it worked fine for what i needed.
you will need to modify the custom xml start and the first part of post data
for your particular host

<?php
//script by Theron Patrick tpatrick_at_swbell.net
// pullpage function by Nick bouton http://www.nickbouton.com/.

$CustomerID = "123456";
$method = "POST";
$host = "[hostserver]"; //just ending in the .com not the whole url
$usepath="[path]"; //the relative path on the srve to the xml post file
example:/xml.asp

//add output tags as necessary to the xml_array.
//only tags in the xml_array will be output.
// They should be set to the matching input form variable so that the form
variable will be input or
//if no form variable submitted the computed output will be sent out

//sample inputs/output

$xml_array[Address]=$HTTP_POST_VARS[Address];
$xml_array[City]=$HTTP_POST_VARS[City];
$xml_array[State]=$HTTP_POST_VARS[State];
$xml_array[Zip]=$HTTP_POST_VARS[Zip];

// create first part of xml post data
$postdata .="<?xml version=\"1.0\" ?><RecordSet><CustomerID>". $CustomerID
."</CustomerID><Record>";

//create middle record data of xml post

while (list($key, $value) = each

       $postdata.= "<". $key.">" .$value."</".$key .">";
  $output_array[$key]="";
}

// append last part of xml post data
$postdata .="</Record></RecordSet>";

// if custom xml disregard above and use custom xml instead
// also, you can comment out the form and post directly to this php script
// setting the posted xml variable name to custom_xml

if($custom_xml){

$postdata ="<?xml version=\"1.0\" ?><RecordSet><CustomerID>". $CustomerID
."</CustomerID>". $custom_xml . "</RecordSet>";

}

//if you do not want the form to show you can comment out the line below
//include('input_form.htm');

function pullpage( $method, $host, $usepath, $postdata) {
# open socket to filehandle
$fp = fsockopen( $host, 80, &$errno, &$errstr, 120 );

  Subject: Retrieving XML file through an HTTP url requiring athentication

        Hello everybody and Happy New Year 2004!

        I have a question for you all:

        I need to retrieve an XML file from an ASP server, so that I can use
it with PHP and XSLT to use the informations the way I want.
        The XML file is generated through an ASPX page under http and it
need a password to be accessible.
        My problem is that if I use the address directly into my borwser
like:
        http : // username:passw@ www .thesite.com /ghj/trioze.aspx , my
browser displays correctly the page.
        Now, using cURL with this code:

          echo "Initializing cURL session...<br>";
          $ch = curl_init("http : // www .thesite.com /ghj/trioze.aspx ");
          echo "Setting cURL options...<br>";
          //curl_setopt($ch, CURLOPT_URL, "http : // www .thesite.com
/ghj/trioze.aspx ");
          curl_setopt($ch, CURLOPT_USERPWD, "username:passw");
          curl_setopt($ch, CURLOPT_FILE, $fp);
          curl_setopt($ch, CURLOPT_HEADER, 1);
          echo "Executing cURL options...<br>";
          curl_exec($ch);
          curl_close($ch);
          fclose($fp);

        I get a 401 Acces Denied error. I know the aspx request is made
through the 'get' method. I know also that cURL is using the same method.
Why does it not work? Is there any additionnal informations I need to send
with the curl_setopt()? Maybe it is too obvious and I am not getting it.
        If anybody can help, that would be fantastic!

        Many thanks anyway!

        Christian
