Generating XML file code, assistance please

Perception

Hi all,

I have been writing a CMS for generating XML files to be used by actionscript, so far I can create new, edit, etc. One of the features requires the playlist to be generated so a user can define the order in which items playout (Digital Signage application) Defining the order is done, I then need to generate an XML file from the playlist.

I can generate this file by reading the directory and stripping out the required tags from each file in the directory using the following code

//read in files
$arr_filename = cms_main::readdir_ext('../../data/');

//parse files for data & load into arrays
$i = $z = 0 ;
	if(isset($arr_filename) && !empty($arr_filename) && $arr_filename != ''){
		foreach($arr_filename as $key => $value){
			$menu_xml = new xmlparser('../../data/'.$value,'r');
			$arr_id[$z]    = $menu_xml->read_section('menu', 'id');
			$arr_subid[$z] = $menu_xml->read_section('menu', 'subid');
			$arr_link[$z]  = $menu_xml->read_section('menu', 'link');
			$z++ ;
			}
			}

// Write new xml file
$xmluser = new xmlparser('../../data/cms_order/play.xml','w');
	$xmluser->xml_declaration();
	$xmluser->xml_section('playorder');
	$i = $z = 0;
	foreach($arr_filename as $key => $value){
			$xmluser->write_value('id', $arr_id[$z]);
			$xmluser->write_value('subid', $arr_subid[$z]);
			$xmluser->write_value('link', $arr_filename[$z]);
			$z++ ;
			}

$xmluser->xml_section_buffer();
$xmluser->xml_section_end('playorder');
$xmluser->_xmlparser();

which generates the following XML

<?xml version="1.0" encoding="utf-8"?>
<playorder>
<id>2</id>
	<subid>-</subid>
	<link>00001.xml</link>
	<id>1</id>
	<subid>3</subid>
	<link>8b1bb.xml</link>
	<id>1</id>
	<subid>2</subid>
	<link>476ff.xml</link>
	<id>1</id>
	<subid>4</subid>
	<link>b95d9.xml</link>
	<id>0</id>
	<subid>-</subid>
	<link>67380.xml</link>
	<id>1</id>
	<subid>-</subid>
	<link>94c6a.xml</link>

</playorder>

However I want to generate the following xml

<?xml version="1.0" encoding="utf-8"?>
<playorder>
<id>2</id>
<file>
	<subid>-</subid>
	<link>00001.xml</link>
	<id>1</id>
</file>
<file>
	<subid>3</subid>
	<link>8b1bb.xml</link>
	<id>1</id>
</file>
<file>
	<subid>2</subid>
	<link>476ff.xml</link>
	<id>1</id>
</file>
<file>
	<subid>4</subid>
	<link>b95d9.xml</link>
	<id>0</id>
</file>
<file>
	<subid>-</subid>
	<link>67380.xml</link>
	<id>1</id>
</file>
<file>
	<subid>-</subid>
	<link>94c6a.xml</link>
<id>1</id>
</file>
</playorder>

I have tried the following

// Write new xml file
$xmluser = new xmlparser('../../data/cms_order/play.xml','w');
	$xmluser->xml_declaration();
	$xmluser->xml_section('playorder');
	$i = $z = 0;
	foreach($arr_filename as $key => $value){
			$xmluser->xml_section('file');
			$xmluser->write_value('id', $arr_id[$z]);
			$xmluser->write_value('subid', $arr_subid[$z]);
			$xmluser->write_value('link', $arr_filename[$z]);
			$xmluser->xml_section_end('file');
			$z++ ;
			}

$xmluser->xml_section_buffer();
$xmluser->xml_section_end('playorder');
$xmluser->_xmlparser();

But all that gives me is :

<?xml version="1.0" encoding="utf-8"?>
<playorder>
<id>2</id>
<file>
</file>
<file>
</file>
<file>
</file>
<file>
</file>
<file>
</file>
<file>
</file>
	<subid>-</subid>
	<link>00001.xml</link>
	<id>1</id>
	<subid>3</subid>
	<link>8b1bb.xml</link>
	<id>1</id>
	<subid>2</subid>
	<link>476ff.xml</link>
	<id>1</id>
	<subid>2</subid>
	<link>476ff.xml</link>
	<id>1</id>
	<subid>4</subid>
	<link>b95d9.xml</link>
	<id>0</id>
	<subid>-</subid>
	<link>67380.xml</link>
	<id>1</id>
	<subid>-</subid>
	<link>94c6a.xml</link>
<id>1</id>
</playorder>

Any and all assistance would be greatly helpful

What is this XmlParser class you're using?

Perception

Sorry ment to include this

function xmlparser($xml_file, $mode){
		// For Remote (only read-only)
		//
		if ($mode == "o"){
			if (!fopen($xml_file, "r")){
				die ("Remote XML-File <b>$xml_file</b> not found!");
			}
		}
		else{
			if ((!file_exists($xml_file)) && ($mode == "r")){
				die ("XML-File <b>$xml_file</b> not found!");
			}
		}

	$this->filename = $xml_file;

	switch ($mode){
	case "r":
		$this->file_handle = fopen($xml_file, "r");
		$this->content = fread($this->file_handle, filesize($xml_file));
		fclose($this->file_handle);
		break;

	case "o":
		ob_start();
		$this->content = ob_get_contents();
		ob_end_flush();
		break;

	case "w":
		// If file exists, open and load in buffer, then we make it writable
		//
		if (file_exists($xml_file)){
			$this->file_handle = fopen($xml_file, "r");
			$this->content = fread($this->file_handle, filesize($xml_file));
			@fclose($this->file_handle);
		}
		else{
			// create, if its not exists
			//
			touch($xml_file);
			chmod($xml_file, 0777);
		}

		while (false == is_writeable($xml_file)){
			sleep(2);
			$this->writings++;

			if ($this->writings > 10)
			{
				die ("<br />Can\'t write to file, BREAK!<br />");
			}
		}

		$this->file_handle = fopen($xml_file, "w");
		break;

	default :
		die ("Unknown modus for XML-File $this->filename.");
	}
}
//*************************************************************
	// Close XML
	//
	function _xmlparser(){
		clearstatcache();
		@fclose($this->file_handle);
	}

also included are the classes for the following

function write_value($tag, $value){
		$this->sections .= "\t<".$tag.">".$value."</".$tag.">\n";
	}

function xml_section_buffer(){
	fwrite ($this->file_handle, $this->sections);
}

function xml_declaration(){
	fwrite ($this->file_handle, '<?xml version="1.0" encoding="utf-8"?>');
}
function xml_section($section){
	fwrite ($this->file_handle, "<".$section.">\n");
}

function xml_section_end($section){
	fwrite ($this->file_handle, "\n</".$section.">\n");
}

I hope this helps, I am better at writing actionscript than php and this has been written with a lot of trial and error

I spent too long looking at the code, all I needed to do was write a new function, sometimes it helps to spend time with your three yr son, it sort of clears the brain. the new function as below


function xml_special_write($tag1, $value1, $tag2, $value2, $tag3, $value3) {
		$this->sections .= "\t<file>\n\t\t<".$tag1.">".$value1."</".$tag1.">\n\t\t<".$tag2.">".$value2."</".$tag2.">\n\t\t<".$tag3.">".$value3."</".$tag3.">\n</file>\n" ;
}

thanks to those who looked
