proXML url parsing issue
Jan 25^th, 2006, 6:52pm

Hello

It seems as though the url parser for the proXML library only handles certain domain names/DNS properly, and not IP addresses & bonjour names.

For example, the following code works in my applet:

Code:


shareAtomFeedIO = new XMLInOut(this);
// load the Atom Feed from the URL. 
shareAtomFeed = shareAtomFeedIO.loadElementFrom("http://share.dj/share/feeds/Multimedia.xml");

this does not:
Code:


shareAtomFeedIO = new XMLInOut(this);
// load the Atom Feed from the URL. 
shareAtomFeed = shareAtomFeedIO.loadElementFrom("http://hokkaido.local/share/feeds/Multimedia.xml");

nor does

Code:


shareAtomFeedIO = new XMLInOut(this);
// load the Atom Feed from the URL. 
shareAtomFeed = shareAtomFeedIO.loadElementFrom("http://127.0.0.1/share/feeds/Multimedia.xml");

I do not get a url lookup error, I recieve a:

Code:


proxml.InvalidDocumentException: This is not a parsable URL
at proxml.XMLInOut.handleStartTag(XMLInOut.java:459)

java.lang.NullPointerException
at Temporary_902_5427.parseAtomXML(Temporary_902_5427.java:120)
at Temporary_902_5427.setup(Temporary_902_5427.java:34)
at processing.core.PApplet.display(PApplet.java:1259)
at processing.core.PGraphics.requestDisplay(PGraphics.java:520)
at processing.core.PApplet.run(PApplet.java:1142)
at java.lang.Thread.run(Thread.java:552)

Is there a chance that proXML could be updated to work with localhost, 127.0.0.1 and rendez... bonjour .local name spaces?

Thank you.

Thanks for the library, btw, I met your partner Markus at Share in NYC, the version of >tree< with audio is really mesmerizing - beautifully done! Heres the Share link : btw http://share.dj/share/event_info.php?eventID=296

Okay I checked it

No idea with the local stuff, I will take a look on that if I have more time.

http://colab.hunter.cuny.edu/colabcms/feeds/Multimedia.xml

This is not working because
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
is missing to make it a valid xml document.

proXML first checks this line because this makes it easy to ensure you really load XML so proXML is not getting into trouble, maybe I will enable proXML to load XML files without this startline.

While I realize that there's a good reason to not parse invalid XML, there are times when someone wants to do so...if you have webspace with PHP you can circumvent this issue with proXML by making a page that is a proxy for the XML you're trying to parse, e.g.,
Code:

<?
header("Content-type: text/xml; charset=UTF-8");
$someurl = "http://colab.hunter.cuny.edu/colabcms/feeds/Multimedia.xml";

$xml = get_file_safely($someurl);

$xml = (preg_match("#^<\?\s?xml\s*version=.+?\?>#", $xml)) ? $xml : '<?xml version="1.0" encoding="UTF-8" standalone="yes"?>'.$xml;

echo $xml;

function get_file_safely($url) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
    $rawhtml = curl_exec ($ch);
    curl_close ($ch); 

return $rawhtml;
}
?>

where $someurl is the .xml file URL you're trying to parse.

If you copy the code above into a file on your server and rename it something like xmlfixer.php, it will take an XML file and look to see if it's missing the beginning <?xml... tag, and add it if it's not there. All you need to do is point proXML at the php file as the URL.
