I am trying to get started with Mirth Connect. want to create a channel that would accept an XML and convert it in to HL7. As a result i wan to create an ADT and OBR messages.

Can anyone help me on this please?

Am sharing my experience that how you can convert XML into HL7 using Javascript codes for source transformer

   var length = msg['orderList']['order'].length();
   var rcount = 0;
   for(var i=0;i<length;i++)
   {
    var SEG = new XML("<OBR/>");
    SEG['OBR.1']['OBR.1.1']=i+1;
    SEG['OBR.16']['OBR.16.1']=msg['orderList']['order'][i]['provider'].toString();
    tmp['OBR'][i]=SEG;
    var reslen = msg['orderList']['order'][i]['result'].length();
    logger.info(reslen);
    for(var j=0;j<reslen;j++)
    {
        var RSEG = new XML("<OBX/>");
        RSEG['OBX.1']['OBX.1.1'] = rcount;
        RSEG['OBX.3']['OBX.3.1'] = msg['orderList']['order'][i]['result'][j]['resultcode'].toString();
        RSEG['OBX.3']['OBX.3.2']=msg['orderList']['order'][i]['result'][j]['text'].toString();
        RSEG['OBX.7'] = msg['orderList']['order'][i]['result'][j]['range'].toString();
        RSEG['OBX.6']['OBX.6.2'] = msg['orderList']['order'][i]['result'][j]['unit'].toString();
        tmp['OBX'][rcount]=RSEG;
        rcount++;
    }
}
logger.info(SerializerFactory.getSerializer('HL7V2').fromXML(tmp));

Dont forgot to create a HL& template in source outbound
