Retrieve aeProjectLink from XMP data with Extendscript
Please help! I am trying to get this path stored as a string /Users/dracusin/Desktop/CollectorTestProject.aep
This is from the files XMP. I can see the line in bridge(vie FileInfo) but not in the AE metadata panel.
Here is my current function:
function GetMetaData(){
var item = app.project.activeItem;
var selectedFile = new File($.fileName);
var itemPath = selectedFile.parent.fsName;
var filePath = itemPath + "/" + item.name;
var fileRef = new File(filePath);if (fileRef instanceof File) {
if (ExternalObject.AdobeXMPScript == undefined) {
ExternalObject.AdobeXMPScript = new ExternalObject('lib:AdobeXMPScript');
}
var xmpFile = new XMPFile(filePath, XMPConst.FILE_UNKNOWN, XMPConst.OPEN_FOR_READ);
var xmp = xmpFile.getXMP();
var newXML = xmp.getProperty(XMPConst.NS_CREATOR_ATOM, 'fullPath');
alert("Error: " + newXML);
xmpFile.closeFile();
}
}
This line returns the correct data for some reason:
var newXML = xmp.getProperty(XMPConst.NS_XMP, ‘CreateDate’).toString();
2019-11-27T19:49:44ZThis line does not:
var newXML = xmp.getProperty(XMPConst.NS_CREATOR_ATOM, ‘fullPath’);
/Users/dracusin/Desktop/TestProject.aepAny ideas?

I couldn’t figure out the clean way to do this — NS_CREATOR_ATOM doesn’t seem to be a registered namespace — so here’s a hacky code fragment to do it instead:
var xmpFile = new XMPFile(filePath, XMPConst.FILE_UNKNOWN, XMPConst.OPEN_FOR_READ);
var xmp = xmpFile.getXMP();// take the whole XMP object and make it into a string so we can parse it manually
var xmpString = xmp.dumpObject().toString();// use a regular expression to find the fullPath item of the aeProjectLink struct of the creatorAtom
var creatorFsName = xmpString.match(RegExp('(.*creatorAtom:fullPath = ")(.*)(")'))[2];alert(creatorFsName);
You should add some error checking to this, because as written, it will fail hard if there’s no project link data.

Thank you Walter! This works perfect for what I need. I was so excited when this worked I jumped out of my seat.
