Olá!
Este procedimento abaixo retorna um dataset com os produtos pronto para serem usados na geração da Danfe, ou seja, já retorna no formato correto para preencher o grid de uma Danfe feita por exemplo com o Report Viwer.
Ele recebe o arquivo xml, e varre as tags gerando um Ds com as mesmas.
private DataSet GeraDsProd(string caminhoXml)
{
DataSet _ds = new DataSet();
DataTable _dt = new DataTable("DetalheNFe");
//Instancia doc com o xml
XmlDocument doc = new XmlDocument();
try
{
//le o xml no caminho correto
doc.Load(caminhoXml);
//le o elemento a ser trabalhado
XmlNodeList No = doc.GetElementsByTagName("prod");
//cria as colunas para serem colocandas no dataset.
_dt.Columns.Add("cProd");
