Why must the entity name immediately follow the '&' in the entity reference appearing for the XML?

I have a XML file called /NewFile.xml in the D: directory. The XML file contains the following details:

<?xml version="1.0"?>
<project>

<logindetails id="1001">
		<url>https:xxx</url>
        <username>xxx</username>
        <password>xxx</password>
</logindetails >

<kpi id="1001">
		<id_r>reports</id_r>
		<id_e>extranet</id_e>
		<id_pr>ext-pr</id_pr>
</kpi>	

<prkpi id="1001">
        <id_1>ext-pr-backlog-age</id_1>
		<id_2>ext-timetoassign-prs</id_2>
		<id_3>ext-timetodeliver-prs</id_3>
		<id_4>ext-timetoresolve-prs</id_4>
		<id_5>ext-new-prs</id_5>

</prkpi>

The following code I'm running in eclipse as follows:

import java.io.File;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import java.util.Properties;

        //use username for webdriver specific actions
        Log.info("Sign in to the OneReports website");
        driver.manage().window().maximize();
        driver.get(url);
        Thread.sleep(5000);
        Log.info("Enter Username");

    }

	private static void waitforElement(WebDriver driver, int i, String string) {
		// TODO Auto-generated method stub
		
	}

	public String readXML(String searchelement,String tag) throws SAXException, IOException, ParserConfigurationException{
        String ele = null;
        File fXmlFile = new File("D://NewFile.xml");
        DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
        DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
        Document doc = dBuilder.parse(fXmlFile);
        doc.getDocumentElement().normalize();
        NodeList nList = doc.getElementsByTagName(searchelement);
        Node nNode = nList.item(0);
        if (nNode.getNodeType() == Node.ELEMENT_NODE) {
        	Element eElement = (Element) nNode;
            ele=eElement.getElementsByTagName(tag).item(0).getTextContent();
        }
        return ele;
    }

}

When running this code I'm getting the following error in the console as follows:

Fatal Error] NewFile.xml:27:57: The entity name must immediately follow the '&' in the entity reference.
Exception in thread "main" org.xml.sax.SAXParseException; systemId: file:/D:/NewFile.xml; lineNumber: 27; columnNumber: 57; The entity name must immediately follow the '&' in the entity reference.

	at A.main(A.java:40)

Please give me a solution for this issue..

You have an unescaped & in there, just like @chrylis says the message says. ;-)

Change Business IAD & Business CPE to Business IAD &amp; Business CPE.

You cannot use an ampersand (&) directly in an XML file. Change this:

1523 Business IAD & Business CPE

to this:

1523 Business IAD &amp; Business CPE

The reason for the somewhat confusing error message is that when an XML processor sees &, it expects it to be immediately followed by an entity name or a "character reference", such as &amp;, &lt;, &#x225b, etc. So it saw the & in your name and didn't guess that you had just used it incorrectly.
