Exception when I parse XML file

when i call mehtod getIdFromDatabasefor get id from my XML database but show me exception [Fatal Error] :1:1: Content is not allowed in prolog.

Call method getIdFromDatabase:

nameLayer =getIdLayerFromDatabase("//Project/Layer[Name="+"'"+Name+"'"+"]/@idLayer","ProjectDataBase.xml");

Method in java:

 public int getIdFromDatabase(String PathXPath, String Path) throws JAXBException {
            int maxid = -1, id = -1;
            DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
            try {
                DocumentBuilder builder = domFactory.newDocumentBuilder();
                //***** exception here****************************** 
                Document dDoc = builder.parse(new InputSource(new ByteArrayInputStream(Path.getBytes("UTF-8"))));
                XPath xPath = XPathFactory.newInstance().newXPath();
                NodeList nl = (NodeList) xPath.evaluate(PathXPath, dDoc, XPathConstants.NODESET);
                for (int i = 0; i < nl.getLength(); i++) {
                    id = Integer.parseInt(nl.item(i).getNodeValue());
                }

            } catch (Exception e) {
                e.printStackTrace();
            }
            return id;
        }

XML File:

<?xml version="1.0" encoding="UTF-8"?>
<Project xmlns="http://www.example.org/ProjectDataBase" name="شئؤ" location="Projects//شئؤ//ProjectDataBase.xml" CreationDate="2014-07-20">
   <Layer idLayer="0">
      <Name>طبقة  1</Name>
   </Layer>
</Project>

The problem is that you're trying to parse the path and not the file. Change the line:

Document dDoc = builder.parse(new InputSource(new ByteArrayInputStream(Path.getBytes("UTF-8"))));

by:

Document dDoc = builder.parse(new FileInputStream(Path));
