C#如何在不删除父节点内部内容的情况下删除单个xml父元素节点

Question

我是C#的新手，请帮助我。如何删除单个xml元素节点"PaymentRecord"和其中不应删除的内容。

<Payments>
<PaymentRecord>
<PayId>2031</PayId>
<Reference>Policy03</Reference>
<StatusCode>ACV</StatusCode>
<MethodDetail>
<PaymentMethodDetail>
<CardPaymentDetails>
<CardHolderName>abcded</CardHolderName>
<CardTransactionDetails>
<StoredCard>N</StoredCard>
</CardTransactionDetails>
</CardPaymentDetails>
</PaymentMethodDetail>
</MethodDetail>
<CurrencyCode>USD</CurrencyCode>
</PaymentRecord>
</Payments>

我需要删除"；付款记录"；元素。我需要像下面这样

<Payments>
<PayId>2031</PayId>
<Reference>Policy03</Reference>
<StatusCode>ACV</StatusCode>
<MethodDetail>
<PaymentMethodDetail>
<CardPaymentDetails>
<CardHolderName>abcded</CardHolderName>
<CardTransactionDetails>
<StoredCard>N</StoredCard>
</CardTransactionDetails>
</CardPaymentDetails>
</PaymentMethodDetail>
</MethodDetail>
<CurrencyCode>USD</CurrencyCode>
</Payments>

我已经尝试了下面的代码，但它删除了我不想做的完整节点：-这里的"queuePayload"是xml元素

XmlNodeList payloadRecordList = queuePayload.SelectNodes("//Payments/PaymentRecord");
foreach (XmlElement singleNode in payloadRecordList)
{
XmlHelper.removeElem((XmlElement)singleNode.ParentNode, "//PaymentRecord");
XmlDocument xmlDoc = singleNode.OuterXml;
// my remaining logic goes based on "xmldoc" value  - I will inserting this data to table
}

Answer 1

您可以使用System.Xml.Linq及其XDocument来实现这一点。加载输入并从中创建一个新文档，如：

XDocument inputDoc = XDocument.Load(inputFile, LoadOptions.None);
XDocument outputDoc = new XDocument();
var elements = inputDoc.Element("Payments").Elements().Select(pr => pr.Elements());
XElement newElement = new XElement("Payments");
foreach (var element in elements)
{
newElement.Add(element);
}
outputDoc.Add(newElement);
Console.WriteLine(outputDoc.ToString());

Answer 2

我认为@Fructzberg有点过于复杂了。

您可以一次性删除PaymentRecord节点并将其所有子节点添加到根节点。

var xDoc = XDocument.Load(filePath);
var paymentRecord = xDoc.Root.Element("PaymentRecord");
var nodes = xDoc.Root.Element("PaymentRecord").Elements();
paymentRecord.Remove();
xDoc.Root.Add(nodes);
Console.WriteLine(xDoc.ToString());
