With using DomDocument class.

Like this:

<?
  $sXML = '<root><element><key>a</key><value>b</value></element></root>';
  $doc = new DOMDocument();
  $doc->preserveWhiteSpace = false;
  $doc->formatOutput   = true;
  $doc->loadXML($sXML);
  echo $doc->saveXML();
?>

From here.

In queries can't be unicode characters, at least, I couldn't find way to do it. Of course, in a result can be unicode characters as I already described. Also, it is very important how do you save your unit, if it is saved as unicode, again, you will have problems.

If you need to redirect page and pass $_POST variable (or any other variable) you should use following code:

<?php
header("HTTP/1.0 307 Temporary redirect");
header("Location: http://localhost/test.php");
?>

I am too lazy, I know.

Here is recursive way:

<?php
	function rec_listFiles( $from = '.')
	{
		if(! is_dir($from))
		return false;

		$files = array();
		if( $dh = opendir($from))
		{
			while( false !== ($file = readdir($dh)))
			{
				// Skip '.' and '..'
				if( $file == '.' || $file == '..')
				continue;
				$path = $from . '/' . $file;
				if( is_dir($path) )
				$files += rec_listFiles($path);
				else
				$files[] = $path;
			}
			closedir($dh);
		}
		return $files;
	}
?>
And here is iterative: 
<?php
	function listFiles( $from = '.')
	{
		if(! is_dir($from))
		return false;
		$files = array();
		$dirs = array( $from);
		while( NULL !== ($dir = array_pop( $dirs)))
		{
			if( $dh = opendir($dir))
			{
				while( false !== ($file = readdir($dh)))
				{
					if( $file == '.' || $file == '..')
					continue;
					$path = $dir . '/' . $file;
					if( is_dir($path))
					$dirs[] = $path;
					else
					$files[] = $path;
				}
				closedir($dh);
			}
		}

		return $files;
	}
?>
Searching for a file in a directory tree: 
<?php
	function rec_listFiles( $fileName, $from = '.', &$pathOut)
	{
		if ($pathOut != '')
			return true;
		else
		{

			if(! is_dir($from))
				return false;

			if( $dh = opendir($from))
			{
				while( false !== ($file = readdir($dh)))
				{
					// Skip '.' and '..'
					if( $file == '.' || $file == '..')
						continue;
					$path = $from . '/' . $file;
					if( is_dir($path) )
					{
						//echo $path.'<p/>';
						rec_listFiles($fileName, $path, $pathOut);
					}
					else
					{
						if ($fileName == $file)
						{
							$pathOut = $path;
						}
					}
				}
			closedir($dh);
			}
			if ($pathOut == '')
				return false;
			else
				return true;
		}
	}

	$pom = '';
	if (rec_listFiles('mod_newsflash.php', '.', $pom))
	echo $pom;
	else
	echo 'Could not find file.';
