[Resolved] How do you parse XML into an array of objects?

[ppowell]

I can't find anything within native PHP to do this: I have to take an XML file and parse it into, not an array proper, but an array of objects.

I don't have a clue as to understanding nodes or blah blah blah so I'm converting it using xml_parse_into_struct() into a 3-dim array and parsing that 3-dim array into an array of objects.

But it doesn't work. Here is my code:

	function &generateResultFromXML($willRetrieveDisplay = false, $willOrder = false) {							// STATIC OBJECT ARRAY METHOD
		global $basePath;		
		$this->clearResult();																				// CLEAR PREVIOUS LATENT RESULTSET OBJECT
		$subSection = $this->getSubSection();
		$fileID = @fopen("$basePath/xml/${subSection}.xml", 'r');
		if (!$fileID) {
		 $this->dbAP->isSuccessful = false;
		 $this->setErrorArray(array('action' => 'Could not retrieve XML file for result generating'));
		} else {
		 $xmlContents = @fread($fileID, filesize("$basePath/xml/${subSection}.xml"));
		 @fclose($fileID);
		}

	if ($this->dbAP->isSuccessful) {
	 $parser = @xml_parser_create();
	 @xml_parser_set_option($parser, XML_OPTION_CASE_FOLDING, 0);
	 @xml_parser_set_option($parser, XML_OPTION_SKIP_WHITE, 1);
	 @xml_parse_into_struct($parser, $xmlContents, $xmlArray, $tags);
	 @xml_parser_free($parser);
	}

	if ($this->dbAP->isSuccessful && is_array($xmlArray) && @sizeof($xmlArray) > 0) {
	 // NOW YOU MUST LOOP THROUGH $xmlArray AND CONVERT IT INTO AN OBJECT ARRAY RESULTSET
	 $result = array();
	 $objKeyArray = @array_keys($xmlArray[1]['attributes']);
	 for ($i = 1; $i < sizeof($xmlArray) - 1; $i++) {
	  array_walk(&$result, 
	   create_function('$a = 0', 'global $objKeyArray; if ($result[$a]) $a++; foreach ($objKeyArray as $field) $a->$field = $xmlArray[$i][\'attributes\'][$field];'),
	  		      $xmlArray);
	  @reset($objKeyArray);
	 }
	}

	if ($this->dbAP->isSuccessful) return $result;

}

Help appreciated!

Thanx

Never mind I got it:

	/**
	 * Generate resultset from XML source
	 *
	 * @access protected
	 * @param boolean $willRetrieveDisplay (default false)
	 * @param boolean $willOrder (default false)
	 * @return object $result
	 */
	function &generateResultFromXML($willRetrieveDisplay = false, $willOrder = false) {							// STATIC OBJECT ARRAY METHOD
		global $basePath;		
		$this->clearResult();																				// CLEAR PREVIOUS LATENT RESULTSET OBJECT
		$subSection = $this->getSubSection();
		$fileID = @fopen("$basePath/xml/${subSection}.xml", 'r');
		if (!$fileID) {
		 $this->dbAP->isSuccessful = false;
		 $this->setErrorArray(array('action' => 'Could not retrieve XML file for result generating'));
		} else {
		 $xmlContents = @fread($fileID, filesize("$basePath/xml/${subSection}.xml"));
		 @fclose($fileID);
		}

	if ($this->dbAP->isSuccessful) {
	 $parser = @xml_parser_create();
	 @xml_parser_set_option($parser, XML_OPTION_CASE_FOLDING, 0);
	 @xml_parser_set_option($parser, XML_OPTION_SKIP_WHITE, 1);
	 @xml_parse_into_struct($parser, $xmlContents, $xmlArray, $tags);
	 @xml_parser_free($parser);
	}

	if ($this->dbAP->isSuccessful && is_array($xmlArray) && @sizeof($xmlArray) > 0) {
	 // NOW YOU MUST LOOP THROUGH $xmlArray AND CONVERT IT INTO AN OBJECT ARRAY RESULTSET
	 $result = array();
	 $objKeyArray = @array_keys($xmlArray[1]['attributes']);
	 for ($i = 1; $i < sizeof($xmlArray) - 1; $i++) {
	  foreach ($objKeyArray as $field) $obj->$field = $xmlArray[$i]['attributes'][$field];
	  array_push($result, $obj);
	  @reset($objKeyArray);
	  $obj = null;
	 }
	}

	if ($this->dbAP->isSuccessful) $this->setResult($result);

}
