本文介绍了如何使用C#在xml中创建节点的智利节点的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
大家好，
我正在尝试使用c#中的数据集ds显示这样的xml文件，我检索了除ward&以外的其余节点值.诊断节点值.
-------------------------------------------------- -----------
< 医院住院 > ;
< 医院住院 =" " >
< 患者ID > REG-10010 < /Patient_Id >
< admission_type > 一般< /admission_type >
< 围场 >
< 病房 =" 2011/08/12" > 区A < /ward >
< 病房 =" 2011/12/12" > Ward B < /ward >
< /沃兹 >
< discharge_details > 31/07 /2010 14:55:49，< /discharge_details >
< 诊断 >
< 条目 > 文本Entery 1 < /entry >
< 条目 > 文本Entery 2 < /entry >
< /diagnosis >
< /医院住院 >
< /医院住院 > ------------------------------------------------ --------------
任何人对此都有任何想法.
谢谢&问候
Huassain 解决方案
我的理解是，您可以访问1级(住院)和2级(患者ID等)，很难达到3级(病房，诊断)
在这种情况下，可以将通用递归多级XML节点获取对数用作:
功能 GetChildren(parentNode as TreeNode) Of Dim 节点 as 列表( Of 字符串)= 新建列表( Of 字符串)
GetAllChildren(parentNode，节点)
返回节点
结束 功能
Sub GetAllChildren(parentNode as TreeNode，节点 as 列表( Of String ))
对于 每个 childNode as TreeNode 在 parentNode.Nodes中
nodes.Add(childNode.Text)
GetAllChildren(childNode，节点)
下一步
结束 功能
DataSet ds = new DataSet ();
ds = Obj_Common.FillDataset("proc_hospitalizationdetails_FORXML 1，" 10004，1"，"TableName");
如果(ds.Tables [0] .Rows.Count> 0)
{
/* ------------------------------------------------ ------------------------------------------- */
XmlDocument xmldoc_PDetail =新的XmlDocument();
//写下XML声明
XmlDeclaration xmlDeclaration = xmldoc_PDetail.CreateXmlDeclaration("1.0"，null，null);
//创建根元素
XmlElement MainNode = xmldoc_PDetail.CreateElement(医院化");
xmldoc_PDetail.InsertBefore(xmlDeclaration，xmldoc_PDetail.DocumentElement);
xmldoc_PDetail.AppendChild(MainNode);
//创建一个新的< Category>元素并将其添加到根节点
XmlElement parentNode = xmldoc_PDetail.CreateElement(医院住院");
parentNode.SetAttribute("Id"，");
//对于父节点的子节点
xmldoc_PDetail.DocumentElement.PrependChild(parentNode);
/*************为XML文件创建字段*****************/
//为父节点创建所需的节点
XmlElement Patient_ID = xmldoc_PDetail.CreateElement("Patient_Id");//''<！[CDATA [< VideoCollection>电影的个人收藏</VideoCollection>]]>''
XmlElement File_Id = xmldoc_PDetail.CreateElement("FileId");
XmlElement date_of_admission = xmldoc_PDetail.CreateElement("date_of_admission");
XmlElement date_of_discharge = xmldoc_PDetail.CreateElement("date_of_discharge");
XmlElementmission_type = xmldoc_PDetail.CreateElement("admission_type");
XmlElement病房= xmldoc_PDetail.CreateElement("Wards");
xmldoc_PDetail.DocumentElement.PrependChild(ward);
DataSet ds1 =新的DataSet();
试试
{
ds1 = Obj_Common.FillDataset("proc_hospitalizationdetails_FORXML 2，" 10004，1"，"Tableward");
如果(ds1.Tables ["Tableward"].Rows.Count> 0)
{
int iJ = 1;
foreach(ds1.Tables ["Tableward"].rows中的DataRow dr1)
{
XmlElement WardNode = xmldoc_PDetail.CreateElement("ward"); //病房节点父节点
XmlText WardNode1 = xmldoc_PDetail.CreateTextNode(dr1 ["WardName"].ToString().Trim());
//WardNode.SetAttribute("DateTime，DateTime.Now.ToString());
WardNode.AppendChild(WardNode1);
ward.AppendChild(WardNode);
}
//for(int i = 0; i< iJ; i ++)
//{
//如果(iJ< 4)
//{
//XmlElement WardNode = xmldoc_PDetail.CreateElement("ward"); //病房节点父节点
//XmlText WardNode1 = xmldoc_PDetail.CreateTextNode("Ward-" + iJ);
//WardNode.SetAttribute("DateTime"，DateTime.Now.ToString());
//WardNode.AppendChild(WardNode1);
//ward.AppendChild(WardNode);
//iJ ++;
//}
//else
//{
//中断；

}
}
赶上

终于
{

Hi to all,
I m trying to show my xml file like this using dataset ds in c#.i retrieve rest of the node value except ward & diagnosis Node value.
-------------------------------------------------------------
<Hospitalizations>
<Hospitalization Id="">
<Patient_Id>REG-10010</Patient_Id>
<admission_type>Genral</admission_type>
<Wards>
<ward Date="08/12/2011">Ward A</ward>
<ward Date="09/12/2011">Ward B</ward>
</Wards>
<discharge_details>31/07/2010 14:55:49,</discharge_details>
<diagnosis>
<entry>Text Entery 1</entry>
<entry>Text Entery 2</entry>
</diagnosis>
</Hospitalization>
</Hospitalizations>
--------------------------------------------------------------
any body have any idea about it.
Thanks & Regards

解决方案 My understanding is that you can access Level 1 (Hospitalization) and Level 2 (Patient_Id,etc), itz hard to pull Level 3 (Wards, Diagnosis)
If that is the case, you can use generic recursive multi level XML node fetch logarithm as:
Function GetChildren(parentNode as TreeNode) as List(Of String)
Dim nodes as List(Of String) = New List(Of String)
GetAllChildren(parentNode, nodes)
return nodes
End Function
Sub GetAllChildren(parentNode as TreeNode, nodes as List(Of String))
For Each childNode as TreeNode in parentNode.Nodes
nodes.Add(childNode.Text)
GetAllChildren(childNode, nodes)
Next
End Function
DataSet ds = new DataSet();
ds = Obj_Common.FillDataset("proc_hospitalizationdetails_FORXML 1,''10004'',1", "TableName");
if (ds.Tables[0].Rows.Count > 0)
{
/*-------------------------------------------------------------------------------------------*/
