Writing to XML file

Hi All,

I was originally going to use .txt files, then thought it'd be way better to use .xml files. So, now I have to write to them. My issue is, how to read between the "lines". Right now I have:

PHP Code:


			
if(isset($_POST['newpost'])){
    //get the info from the form, post to text file.
    $title = stripslashes($_POST['title']);
    $category = stripslashes($_POST['category']);
    $body = stripslashes($_POST['body']);
    
    //add data XML style
    $data = "<post>" . "\n" . "<category>". $category . "</category>" . "\n" . "<title>" . $title . "</title>" . "\n" . "<date>" . $todaysdate . "</date>" . "\n" . "<body>" . "\n". $body . "</body>" . "\n" . "</post>". "\n\r";
    
    //add data to CSV Text File
    //$data = $category . "||" . $title . "||" . $body . "\n";
    //open file and store contents
    $file = fopen('posts.xml','a+');
    if (!$file) {echo 'ERROR: Unable to open file.'; exit;} 
    //post current post, then write $currentdata back to file
    // Write the data to the file
    fwrite($file, $data);
    // Close the file
    fclose($file);
    
    $postupdated = "You have created a new post!";
}

...which posts fine to the file. However, if I have:

Code:

<?xml version="1.0" standalone="yes"?>
<posts>
  <post>
    <title>Some people like meat.</title>
    <category>Meat</category>
    <pubDate>2008-January-15</pubDate>
  </post>
</posts>

What is the best way to get the <posts> and then write to it without messing the xml file up?

Code:

<?xml version="1.0" standalone="yes"?>
<posts>
     //insert $data here
</posts>

What I am thinking is I should get all the <post> data from the XML file and store it in $dataxml then add $data to it, then write it back to the file.

Would that be the best way?

Thanks
