The way to order the nodes in XML-files by an attribute (desc or asc):



<?php

// open the XML-file

$xml = domxml_open_file("our_file.xml");



// get the root element

$root = $xml->document_element(); 

// get the list of the nodes

$nodes = $root->child_nodes(); 



// create the array 'messages' of the nodes

foreach($nodes as $node)

{

 if ($node->node_name() == 'photo')

 {

     $currentMessage['thumbnail'] = $node->get_attribute('thumbnail');

     $currentMessage['filename'] = $node->get_attribute('filename');

     $currentMessage['idnum'] = $picnum[md5($node->get_attribute('filename'))];

     $messages[] = $currentMessage;

 }

}



// sort all the nodes by idnum (asc/desc is "1: -1" or "-1: 1")

$compare_func = create_function('$a, $b', 'return ($a[\'idnum\']==$b[\'idnum\'])? 0: (($a[\'idnum\']>$b[\'idnum\'])? 1: -1);');

usort($messages, $compare_func);



// create the new XML-data

$doc = domxml_new_doc("1.0");

$root = $doc->create_element("photos");

$root = $doc->append_child($root);

for($ee=0;$ee<count($messages);$ee++)

{

    $msgNode = $root->new_child('photo');

    foreach($messages[$ee] as $description => $result)

    {

        $msgNode->set_attribute($description,$result);

    }

}



// write down the XML-file

$text = $doc->dump_mem(true);

$fp = fopen("our_file.xml","w");

fwrite($fp,$text);

fclose($fp);

?>

A very useful undocumented feature if you are opening hundreds of xml docs (my script processes 20,000) is DomDocument->free.

This clears the allocated the memory used by the xml file which is not done automatically by just opening a new file on the same variable.



Example:



<?

$dir="/path/to/xml/files/";

if ($dh = opendir($dir)) {

    while (($file = readdir($dh)) !== false) {

        if(is_file($dir.$file))

        {

            echo $file . "\\n";

            $dom=domxml_open_file($dir.$file);



            #...

            #You xml processor here

            #...

            $dom->free();

        }

    }

    closedir($dh);

}



?>

But. if thr path is some hipelink like www.somth.com/data.xml

another way to resolve path's problem is to use  realpath() function

for example:



<?php

$file=$_REQUEST['file'];

$xmlPath = realpath("../xml/");

$fileXML ="$file";

  if(!$dom = domxml_open_file($xmlPath."/".$fileXML)) {

    echo "error opening the file";

    exit;

}

?>



N.B. you have to put the final slash ( / ) beetween path and file name!

For me, on Windows XP, the solution with  file_get_contents works, the one with domxml_open_file does not. It seems the latter caches the loaded file. Quite confusing.

If you want to work on both Windows and Linux, I found appending the following to the front of your file path works:



$xmlPath = dirname(__FILE__) . "/";

$xmlDOM = domxml_open_file($xmlPath . "file.xml");



(rather than the "\\" in a previous post on this page which only works on Windows).



This should get around the I/O errors.

You can load your own DTD's within your XML Doc like this:



<?php

$domxml = domxml_open_file('test.xml',DOMXML_LOAD_VALIDATING,$error);

?>



I hope this helps....

If you're working on a windows machine and don't want to use full paths , just use...



$showfile = file_get_contents($path . "/" . $fileName);



if(!$domDoc = domxml_open_mem($showfile)) {

    echo "Couldn't load xml...";    

    exit;

}



Because file_get_contents() can use relative paths on Win, it keeps your code more portable...

domxml documentation is a moving target, for 4.2.3 a working example is:



<?

$xmlpath = dirname(__FILE__) . "\\";

$xmldoc = domxml_open_file( $xmlpath . "test.xml");

$xsldoc = domxml_xslt_stylesheet_file ( $xmlpath . "test.xsl");

$result = $xsldoc->process($xmldoc);

print $result->dump_mem();

?>



RTFS is a working method in this case (lucky guesses work also from time tor time) :-)

Using PHP 4.2.3 and Win2K.



The XML file needs to be referenced using the full filesystem path name, even if its in the same directory.

Using PHP 4.1.2, Win2K, IIS.

I found that if the path to the XML source file is too long then the file isn't picked up. I haven't tested it to see how long the path can be or whether this is still an issue in PHP 4.2
