指定的节点不能作为该节点的有效子节点插入,因为指定的节点类型错误
本文关键字:节点 因为 错误 插入 类型 不能 有效 子节点 | 更新日期: 2023-09-27 18:06:44
我通过c#代码动态构建xml,我得到这个错误
"指定的节点不能作为此节点的有效子节点插入节点,因为指定的节点是错误的"
这是我的主类
internal class Program
{
private static void Main(string[] args)
{
CreateXml xml = new CreateXml();
xml.multipleXML();
}
}
我已经评论为"错误"下面,我得到运行时异常。请帮忙解决这个错误。
My Xml Class is here.
internal class CreateXml
{
private XmlDocument HandlingXmlDoc;
private String baseHandlingXML = "<?xml version='"1.0'" encoding='"utf-8'"?><SHandling><BLocation><SLocation><Identifier>02898</Identifier></SLocation></BLocation><Context><UserName>0289800001</UserName><Application>STOCK</Application></Context><Counting><SubmissionDateTime>2014-04-02T16:38:48.9345238+01:00</SubmissionDateTime><ProcessImmediately>YES</ProcessImmediately><Counts><Count><ProductIdentifier>050025488</ProductIdentifier><CountDateTime>2014-04-02T16:38:49.366567+01:00</CountDateTime><LocationCounts></LocationCounts></Count></Counts></Counting></SHandling>";
private XmlDocument locCountXmlDocument;
private String baseLocCountXML = "<LocationCount><Name>Bangalore</Name><SCounts><SCount><Quantity>1</Quantity><UnitOfMeasure>CASES</UnitOfMeasure></SCount><SCount><Quantity>1</Quantity><UnitOfMeasure>SINGLES</UnitOfMeasure></SCount></SCounts></LocationCount>";
public CreateXml()
{

HandlingXmlDoc.LoadXml(baseHandlingXML);

locCountXmlDocument.LoadXml(baseLocCountXML);

public void multipleXML()
{
XmlNode countNode = HandlingXmlDoc.CreateNode(XmlNodeType.Element, "Count", null);
XmlNode productIdentifierNode = HandlingXmlDoc.CreateNode(XmlNodeType.Element, "ProductIdentifier", null);
productIdentifierNode.InnerText = "123345";
XmlNode countDateTimeNode = HandlingXmlDoc.CreateNode(XmlNodeType.Element, "CountDateTime", null);
countDateTimeNode.InnerText = DateTime.Now.ToString();
//XmlNode locationCountNode = HandlingXmlDoc.CreateNode(XmlNodeType.Element, "LocationCounts", null);
countNode.AppendChild(productIdentifierNode);
countNode.AppendChild(countDateTimeNode);
countNode.AppendChild(SetNewLocation("Bangalore","30","30"));//ERROR

}
private XmlNode SetNewLocation(String location, String casesQuantity, String singlesQuantity)
{
XmlDocument docCountXml = new XmlDocument();
docCountXml.LoadXml(baseLocCountXML);
SetValue(docCountXml, "LocationCount/Name", location);
var xmlNodeList = docCountXml.SelectNodes("LocationCount/SCounts/SCount/Quantity");
xmlNodeList[0].FirstChild.Value = casesQuantity;
xmlNodeList[1].FirstChild.Value = singlesQuantity;
return docCountXml.SelectSingleNode("/");
}
private static void SetValue(XmlDocument xmlDocument, String key, String value)
{
var xmlNode = xmlDocument.SelectSingleNode(key);
xmlNode.FirstChild.Value = value;
}
}
问题是您正在插入来自不同xml的外部xmlnode。
我的编辑在这里,我使用了一种变通方法来加载新文档中的xmlnode,然后将其附加到节点
countNode.AppendChild(countNode.OwnerDocument.ImportNode(test, true));
试试这个解决方案
public void multipleXML()
{
XmlNode countNode = HandlingXmlDoc.CreateNode(XmlNodeType.Element, "Count", null);
XmlNode productIdentifierNode = HandlingXmlDoc.CreateNode(XmlNodeType.Element, "ProductIdentifier", null);
productIdentifierNode.InnerText = "123345";
XmlNode countDateTimeNode = HandlingXmlDoc.CreateNode(XmlNodeType.Element, "CountDateTime", null);
countDateTimeNode.InnerText = DateTime.Now.ToString();
//XmlNode locationCountNode = HandlingXmlDoc.CreateNode(XmlNodeType.Element, "LocationCounts", null);
countNode.AppendChild(productIdentifierNode);
countNode.AppendChild(countDateTimeNode);
var test = SetNewLocation("Bangalore", "30", "30");
countNode.AppendChild(countNode.OwnerDocument.ImportNode(test, true));
//countNode.AppendChild(test);//ERROR
HandlingXmlDoc.SelectSingleNode("//SHandling//Counting//Counts").AppendChild(countNode);
}
和SetNewLocation函数中的另一个编辑
(my edit return docCountXml.SelectSingleNode("LocationCount");
)
private XmlNode SetNewLocation(String location, String casesQuantity, String singlesQuantity)
{
XmlDocument docCountXml = new XmlDocument();
docCountXml.LoadXml(baseLocCountXML);
SetValue(docCountXml, "LocationCount/Name", location);
var xmlNodeList = docCountXml.SelectNodes("LocationCount/SCounts/SCount/Quantity");
xmlNodeList[0].FirstChild.Value = casesQuantity;
xmlNodeList[1].FirstChild.Value = singlesQuantity;
return docCountXml.SelectSingleNode("LocationCount");
}
