'Get an element from XML file with all namespaces in the file and declarations
Here is my XML file

I want to retrieve the SignedProperties element. Sample Output that i need looks like
<?xml version="1.0" encoding="UTF-8"?> <xades:SignedProperties xmlns="urn:oasis:names:specification:ubl:schema:xsd:Invoice-2" xmlns:cac="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2"
xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2" xmlns:ds="http://www.w3.org/2000/09/xmldsig#"
xmlns:ext="urn:oasis:names:specification:ubl:schema:xsd:CommonExtensionComponents-2" xmlns:sac="urn:oasis:names:specification:ubl:schema:xsd:SignatureAggregateComponents-2" xmlns:sbc="urn:oasis:names:specification:ubl:schema:xsd:SignatureBasicComponents-2"
xmlns:sig="urn:oasis:names:specification:ubl:schema:xsd:CommonSignatureComponents-2" xmlns:xades="http://uri.etsi.org/01903/v1.3.2#" Id="xadesSignedProperties">
<xades:SignedSignatureProperties>
<xades:SigningTime>020-12-25T12:57:51Z</xades:SigningTime>
<xades:SigningCertificate>
<xades:Cert>
<xades:CertDigest>
<ds:DigestMethod Algorithm="http://www.w3.org/2001/04/xmlenc#sha256"/>
<ds:DigestValue> <!-- SOME VALUE HERE --></ds:DigestValue>
</xades:CertDigest>
<xades:IssuerSerial>
<ds:X509IssuerName> <!-- SOME VALUE HERE --></ds:X509IssuerName>
<ds:X509SerialNumber> <!-- SOME VALUE HERE --></ds:X509SerialNumber>
</xades:IssuerSerial>
</xades:Cert>
</xades:SigningCertificate>
</xades:SignedSignatureProperties>
</xades:SignedProperties>
But I am getting output without the namespaces in the file like,
<?xml version="1.0" encoding="UTF-8"?> <xades:SignedProperties Id="xadesSignedProperties" xmlns:xades="http://uri.etsi.org/01903/v1.3.2#">
<xades:SignedSignatureProperties>
<xades:SigningTime>2020-12-25T12:57:51Z</xades:SigningTime>
<xades:SigningCertificate>
<xades:Cert>
<xades:CertDigest>
<ds:DigestMethod Algorithm="http://www.w3.org/2001/04/xmlenc#sha256"/>
<ds:DigestValue> <!-- SOME VALUE HERE --></ds:DigestValue>
</xades:CertDigest>
<xades:IssuerSerial>
<ds:X509IssuerName> <!-- SOME VALUE HERE --></ds:X509IssuerName>
<ds:X509SerialNumber> <!-- SOME VALUE HERE --></ds:X509SerialNumber>
</xades:IssuerSerial>
</xades:Cert>
</xades:SigningCertificate>
</xades:SignedSignatureProperties>
</xades:SignedProperties>
The code which i used to retrieve the element is as follow,
try {
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(file);
XPathFactory xPathfactory = XPathFactory.newInstance();
XPath xpath = xPathfactory.newXPath();
XPathExpression expr = xpath.compile(tagPath);
Node node = (Node)expr.evaluate(doc, XPathConstants.NODE);
StreamResult xmlOutput = new StreamResult(new StringWriter());
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.setOutputProperty("omit-xml-declaration", "no");
transformer.transform(new DOMSource(node), xmlOutput);
return xmlOutput.getWriter().toString();
}
catch (Exception e) {
}
How should i get the element with all the namespaces declared in the XML file?
