我有一个销售量很大的XML文件，并且在销售量中我有多个项目。 问题是：我找不到要在产品上进行迭代的解决方案
将销售分成“ CFe”标签。我正在对该标签进行迭代，当我到达商品标签时，我会尝试再次进行迭代，但仅对单个商品进行迭代。
我只注意到在nCFe 120476中有5个项目。
这是代码
foreach (var file in files)
{
if (Path.GetExtension(file) == ".xml")
{
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(file);
XmlNodeList cfes = xmlDoc.GetElementsByTagName("CFe");
foreach (XmlNode cfe in cfes)
{
XmlNode infcfe = cfe.ChildNodes[0];
string UF = infcfe["ide"]["cUF"].InnerText;
string NF = infcfe["ide"]["cNF"].InnerText;
string nCFe = infcfe["ide"]["nCFe"].InnerText;
DateTime dataMovimento = DateTime.ParseExact(infcfe["ide"]["dEmi"].InnerText, "yyyyMMdd", CultureInfo.CurrentCulture);
foreach (XmlNode node in infcfe["det"])
{
if (node.Name == "prod")
{
string cProd = node["cProd"].InnerText;
string xProd = node["xProd"].InnerText;
string Ncm = node["NCM"].InnerText;
}
if (node.Name == "imposto")
{
string elementName = node.ChildNodes[1].InnerXml.Substring(1,9);
}
}
}
}
}
我认为问题出在这里： foreach（infcfe [“ det”]中的XmlNode节点） 当我通过infcfe [“ det”]调试时，我有2个项目，而XML文件有5个项目。
这是XML的一部分：

欢迎来到stackoverflow！ 使用迭代器只会给您第一个子元素。 我相信您需要使用XmlNode.SelectNodes Method。 修改您的代码，如下所示：
foreach (XmlNode node in infcfe.SelectNodes("det"))
{
//...
}
