import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.DocumentHelper;
import org.dom4j.Node;

public class EcrvIdUpdate {
    public String updateEcrvWithCountyId(String eCRV, String newCrvIdResponse) throws DocumentException {
        String theId = null;
        Document responseDoc = DocumentHelper.parseText(newCrvIdResponse);
        Node countyIdNode = responseDoc.selectSingleNode("/response/county-id");
        Node currentYearNode = responseDoc.selectSingleNode("/response/current-year");
        Node sequenceIdNode = responseDoc.selectSingleNode("/response/sequence-id");

        theId = countyIdNode.getText() + "-" + currentYearNode.getText() + "-" + sequenceIdNode.getText();

        Document document = DocumentHelper.parseText(eCRV);
        Node node = document.selectSingleNode("/eCRVDocument/DocumentIDs/mnr-ptx:CRVStateAssignedID");

        node.setText(theId);
        String modifiedEcrv = document.asXML();
        return modifiedEcrv;


    }
