Add keywords with script - XMP

[LeoMari-eL6mBl]

Hello everyone!

I need a script to add words in my keywords. It's possible?

I'm trying this:

activeDocument.XMPString ("ok Script");

ActiveDocument.Save (); // dont work

Thank cooperation!

function save(doc, path){

    try{

        doc.save();

    }catch(e){

        doc.saveAs( Folder(path) );

    }

}

save( app.activeDocument, '~/Desktop' );

Try it:

var key = prompt("Input keyword","");
if (key!=null) {
  var st = app.activeDocument.XMPString;
  var str = "";
  if (st.match(/dc:subject/)==null) {
     str = "<dc:subject><rdf:bag><rdf:li>"
        + key + "</rdf:li></rdf:bag></dc:subject></dc:title>";
     st.replace("</dc:title>",str);
     app.activeDocument.XMPString = st;
  }
  else {
     str = "<rdf:li>" + key + "</rdf:li></rdf:Bag>";
     st = st.replace("</rdf:Bag>",str);
     app.activeDocument.XMPString = st;
  }
  app.activeDocument.save();
}

Hello my friends,

I ran the scripts but my Keywords still empty.

Am I doing something wrong?

Thanks for the collaboration..

As an option:

function save(doc, path, name){

    try{

        doc.save();

    }catch(e){

        doc.saveAs( File(path + '/' + name) );

    }

}

function setKeywords(keywords){

    var xmp = activeDocument.XMPString.toString(),

        startSubject = '<dc:subject><rdf:Bag>',

        endSubject = '</rdf:Bag></dc:subject>',

        words = keywords.split('\n');

        keywords = '';

    for(var i = 0; i < words.length; i++){

        keywords += '<rdf:li>' + words + '</rdf:li>';

    }

    if( xmp.indexOf(startSubject) > 0 ){

        activeDocument.XMPString = xmp.replace( xmp.slice(xmp.indexOf(startSubject) + startSubject.length, xmp.indexOf(endSubject)), keywords );

    }

        else{

            activeDocument.XMPString = xmp.replace('</dc:title>', '</dc:title>' + startSubject + keywords + endSubject);

        }

    save( app.activeDocument, '~/Desktop', 'Add keywords from script' );

}

setKeywords('One\nTwo\nThree\nFour\nFive');
