I'm trying to build a Quartz Composition that uses an XML file as a
data source. What I need is similar to the RSS patch, but
retrieving arbitrary XML. I've tried the JavaScript patch, but it
appears not to support the
For example, if I create a JavaScript patch with this script:
req = new XMLHttpRequest();
req.onreadystatechange = processReqChange;
req.open("GET", url, true);
req.send(null);
I get the error "Can't find variable: XMLHttpRequest".
I know that I could write a Cocoa app that retrieves the XML and
passes it into Quartz to render, but that would mean that my
composition can't run as a screen saver, in QuickTime, etc.,
wherever a Quartz Composition can run. And it'd also make the
development loop slower (sigh) having to bounce between QC and IB.
Any suggestions?
