XML Error - Extra content at end of document? - php

Question

My XML is looking perfect but not working. I get a error on line 2 at column 1: Extra content at the end of the document
Other answers from other posts aren't helping
<?php
$csv = array_map(function($v){return str_getcsv($v, "|");},file('quotes.csv'));
$hdrs = array_shift($csv);
$count = 0;
$xml = '<?xml version="1.0" encoding="UTF-8"?>';
$xml .= '<quotes>';
foreach($csv as $k=>$v) {
$xml .= '<record id="' . ++$count .'">';
foreach($hdrs as $h=>$i) {
$xml .= '<' . $i . '>' . htmlspecialchars($v[$h], ENT_XML1, 'UTF-8') . '</' . $i . '>';
}
$xml .= '</record>';
}
$xml .= '</quotes>';
header ("Content-Type:text/xml");
echo $xml;
?>
Expected Output
<quotes>
<record id="1">

Answer 1

Use the XMLWriter, its quite easy and it will generate valid XML. Doing your own manually is always likely to cause little anomalies.
$lines = array_map(function($v){return str_getcsv($v, "|");},file('quotes.csv'));
$hdrs = array_shift($lines);
$count = 0;
header ("Content-Type:text/xml");
$xml = new XMLWriter();
$xml->openUri('php://stdout');
$xml->startDocument();
$xml->setIndent(true);
$xml->startElement('quotes');
foreach($lines as $line) {
$xml->startElement("record");
$xml->writeAttribute('id', ++$count);
foreach($hdrs as $i=>$name) {
$xml->writeElement($name, htmlspecialchars($line[$i], ENT_XML1, 'UTF-8') );
}
$xml->endElement();
}
$xml->endElement();
$xml->endDocument();
$xml->flush();
