Server A using xmlreader to read XML from xmlwriter on server B

Question

I have two servers

Server A reads http://www.some-url.com/xmlwriter_src.php using

$reader = new XMLReader();
$reader->open('http://www.some-url.com/xmlwriter_src.php');
while ($reader->read()) 
{
  /* -- do something -- */
}

Server B creates an xml stream

$writer = new XMLWriter();
$writer->openURI('php://output');
$writer->startDocument("1.0");

$writer->startElement("records");
while(!$recordset->EOF)
{
  $writer->startElement($fieldname) 
  $writer->text($recordset->fields[$fieldname]);
  $writer->endElement();
  $recordset->movenext();
}

the xmlreader on server A keeps complaining that server B doesnt respond, even though I can see the xml result in the browser.

It takes less than a second to generate

If i copy the xml to a static file, the xmlreader outputs the file.

By default the writter will buffer your output. Once you are done you MUST call flush().

$writer = new XMLWriter();
$writer->openURI('php://output');
$writer->startDocument("1.0");

$writer->startElement("records");
while(!$recordset->EOF)
{
  $writer->startElement($fieldname) 
  $writer->text($recordset->fields[$fieldname]);
  $writer->endElement();
  $recordset->movenext();
}
$writer->flush();

By the way: where do you close the records element?
