List files from directory in XML file

[maxabee]

Hello,

I have a photo gallery app that displays images from an xml file.

What I would like is a way to get the xml file to list all files in a given directory rather than having to type them in manually.

The xml format is like:
<images>
<image>images/image1.jpg</image>

<image>images/image2.jpg</image>

<image>images/image3.jpg</image>

<image>images/image4.jpg</image>

<image>images/image5.jpg</image>
</images>

Any ideas?

Thanks!

seeing that the format of the xml file is structured why dont u just right a php function that will grab the edit the file continuosly grabbing the file names out of the xml doc and putting them into an array.

(use a copy not the orginal)

1. open xml file
2. start a loop that will end once it finds </images>
3. as long as condition is true find the part between <image>sss</image>
4. insert into array
   delete this part from the xml file.
5. loop

duno if that would do the job?

you could also check out the php manual, look under the xml functions. i think you might a function there that does what you are looking for.

This is what I ended up with, found some other tips at Kirupa.com:

Function right($rightstring, $rightlength) {
return(substr($rightstring, -$rightlength));
}

$filename="images.xml";
$imgdirname = "../../homepageslides/";
$gallerypath=$imgdirname."/";
$file=fopen($filename, "w") or die("Could not open $filename!");
fwrite($file, "<images path=\"".$gallerypath."\">");
$q=0;
$imgdir = opendir($imgdirname);
//echo "Reading directory $imgdirname ...\n";
While (False != ($imgfile = ReadDir($imgdir) ) )
{
If( ($imgfile != ".") And ($imgfile != "..") )
{

	If (Right($imgfile, 4) == ".jpg")
	{
		$imgfilename[$q] = $imgfile;
		fwrite($file, "<pic><image>[url]http://www.url.com/homepageslides/[/url]$imgfile</image><caption></caption></pic>");
		//echo "Wrote $imgfile \r";
		$q++;
	}
}

}
CloseDir($imgdir);
fwrite($file, "</gallery>");
fclose($file);
echo "Slideshow Update Complete"

Thanks for your help!
