Preciso ler um arquivo XML de lote de nota fiscal e retirar apenas o elemento NFe dele. Preciso fazer isso para juntar o NFe com o protNFe para gerar o XML de envio para o destinatário da nota fiscal. Como faço isso…

Como ler um lote em XML com o XStream?

Adicionando mais informações....

Estou tentando:

XStream x = new XStream();
x.alias("enviNFe", TEnviNFe.class);

TEnviNFe lote = (TEnviNFe) x.fromXML(new BufferedReader(new FileReader(arq)));
System.out.println("ID do lote: " + lote.getIdLote());

Mas está dando esse erro:

Exception in thread "main" com.thoughtworks.xstream.converters.ConversionException: NFe : NFe : NFe : NFe

O XML é um arquivo de lote com apenas 1 nota fiscal:

<?xml version="1.0" encoding="UTF-8"?>
<enviNFe xmlns="http://www.portalfiscal.inf.br/nfe" versao="2.00">
    <idLote>000001</idLote>
    <NFe>
        <infNFe Id="NFe35101002767116000186550010000000011010848149" versao="2.00">
            ...
        </infNFe>
        <Signature xmlns="http://www.w3.org/2000/09/xmldsig#">...</Signature>
    </NFe>
</enviNFe>

Mudando um pouco o assunto.

Como faço nesse meu código para pegar o nó inteiro (NFe) como uma String?

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db;
Document doc;
try {
    db = dbf.newDocumentBuilder();
    doc = db.parse(file);
    doc.getDocumentElement().normalize();

    System.out.println("RAIZ: " + doc.getDocumentElement().getNodeName());
    NodeList lista = doc.getElementsByTagName("NFe");
    
    for (int k = 0; k < lista.getLength(); k++) {
        Node nodeNfe = lista.item(k);
        // Quero pegar esse nó inteiro como um XML em texto
        System.out.println("NFe:\n" + nodeNfe.getNodeName());
        System.out.println("");
    }
} catch (ParserConfigurationException ex) {
    Logger.getLogger(LerLote.class.getName()).log(Level.SEVERE, null, ex);
} catch (SAXException ex) {
    Logger.getLogger(LerLote.class.getName()).log(Level.SEVERE, null, ex);
}

Com xstream eu não consigo colocar no objeto nem a pau!!
