Hi I'm using a class to parse my XML.
I have to parse request XML and response XML, and I'd like to do it with the same parser. When I parse the response XML, I keep getting junk after document element error.
I narrowed my XML down to <?xml version="1.0" encoding="UTF-8" ?><check></check> and I'm still getting the error, so the only thing I could think of is the second <?xml ..?> header being parsed as 'junk'.
What I basically want to do is reset the XML parser so it can start off as a new document, but I don't want to create a new parser object. Is this possible?
Edit:
I'm using the following code in my XmlParser object.
<?php
class XmlComponent extends Object {
private $parser, $c, $current_tag;
public $contents;
function initialize(&$controller, $settings = array())
{
$this->controller =& $controller;
$this->parser = xml_parser_create();
xml_set_object($this->parser, $this);
xml_set_element_handler($this->parser, "tag_open", "tag_close");
xml_set_character_data_handler($this->parser, "cdata");
xml_parser_set_option($this->parser, XML_OPTION_CASE_FOLDING, 0);
if (isset($settings['xml'])) {
$contents = $settings['xml'];
}
if (isset($settings['file'])) {
$f = fopen($settings['file'], 'r');
$contents = fread($f, filesize($settings['file']));
fclose($f);
}
debug($this->parse($contents));
}
public function parse($xml)
{
$xml = trim(preg_replace("/>\s+</", '><', $xml));
$this->contents = array();
$this->c = &$this->contents;
xml_parse($this->parser, $xml);
return xml_error_string(xml_get_error_code($this->parser))."\r\n".$xml;
}
//*/
public function xml($root)
{
$xml = '';
foreach ($root as $tag=>$elem) {
if (substr($tag, 0,1) != '@') {
foreach ($elem as $val) {
$xml .= '<'.$tag;
if (is_array($val) && isset($val['@attributes'])) {
foreach($val['@attributes'] as $a_key => $a_val) {
$xml .= ' '.$a_key.'="'.$a_val.'"';
}
}
$xml .= '>';
if (is_array($val) && isset($val['@data'])) {
$xml .= $val['@data'];
}
$xml .= $this->xml($val);
$xml .= '</'.$tag.'>';
}
}
}
return $xml;
}

private function tag_open($parser, $tag, $attributes)
{
if (!empty($attributes)) { $this->c[$tag][] = array('@attributes' => $attributes, '@parent' => &$this->c); }
else { $this->c[$tag][] = array('@parent' => &$this->c); }
$this->c =& $this->c[$tag][count($this->c[$tag]) - 1];
