Bulk convertion of xrefs to text

this might work for one file you opened:

var doc = app.FirstOpenDoc;
//get the map of the xml file:
var tempxmlMap = ReadXML(doc.Name)
//gather xrefs from the map:
var xmlXRefs = tempxmlMap..xref;
//loop through the xrefs found in the map:
for( var i = 0; i < xmlXRefs.length( ); i++ ) {
    var sHref = xmlXRefs.@href.toString( );
    //PartofsHref = sHref.replace(/#.*/g, "") //use regex magic to extract the part of the xref you need
    var xrefList=new File("D:\\xref.txt");
    if(!xrefList.exists) {
                xrefList.open('w');
            } else {
                xrefList.open('a');
            }
    xrefList.writeln(doc.Name + "\trefers to:\t" + sHref); //or PartofsHref instead of sHref
    xrefList.close();
}
//function to get check validity and get the map:
function ReadXML(filename) {
    var xmlMap;
    var oFile = File(filename);
    if( oFile.open( 'r' ) ){
        sContents = oFile.read( oFile.length );
        oFile.close( );
        try {
            xmlMap = new XML( sContents );
        }
        catch(err) {
            $.writeln(filename + "\t" + err.toString().replace("\n", " "))
            return false
        }
    }
    return xmlMap;
}

you may adapt the script to make it loop through several files.
