Searching with XML

Hi,

I have been given an XML database to work with which i have never worked with before. What i need to do is convert the following php code to work with an XML database?

<?php
	$search_text=trim($_POST['search_text']);

		$kt=split(" ",$search_text);//Breaking the string to array of words
			// Now let us generate the sql 
		while(list($key,$val)=each($kt)){
		if($val<>" " and strlen($val) > 0){$q .= " title like '%$val%' or ";}
									
		$q=substr($q,0,(strLen($q)-3));
		// this will remove the last or from the string. 
		$query="select * from news where $q ";
		$nt=mysql_query($query);
		$countrowssa = mysql_num_rows($nt);
			if ($countrowssa < 1){
				echo "Sorry there are no results matching your search criteria, Please try again.";
								 }
				echo mysql_error();
			while($row=mysql_fetch_array($nt)){

  print $row[title];
	
		} // End if form submitted
?>

Code (markup):

Any ideas how i can get this to work with an XML database?

Cheers,
Adam

 

Anyone know how i would do this?

 

I think you're not describing clearly enough what you want to do. Also, an example of this XML database would be quite helpful.

 

Basically the top example of code searches a table called news in an SQL database.

I want to use this same code but in place of searching a table in an SQL database i want to search a XML database called db.xml
