得到一个需要处理的XMl
private string GetSaveItem()
{
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml("<menuCollection/>");
foreach (TreeNode node in trvAccessRight.CheckedNodes)
{
if (node != trvAccessRight.Nodes[0])
{
XmlElement content = xmlDoc.CreateElement("menuItem");
content.SetAttribute("menuID", node.Value);
xmlDoc.DocumentElement.AppendChild(content);
}
}
return xmlDoc.OuterXml;
}
将以上的获得的XMl字符串当参数传入存储过程中，
存储如下写
ALTER PROCEDURE [dbo].[usp_UserGroup_SetRight]
(@GroupID INT ,@ChangedBy VARCHAR(50) ,@MenuXml XML)
AS
BEGIN
--SET XACT_ABORT ON
BEGIN TRY
BEGIN TRANSACTION
--delete
DELETE
from tbl_SysUserGroupRight
WHERE GroupId = @GroupID
--insert
INSERT INTO tbl_SysUserGroupRight
(
GroupId
,MenuID
,ChangedBy
,ChangedOn
)
SELECT @GroupID
,menuList.row.value(N'@menuID' ,'VARCHAR(50)') AS MenuID
,@ChangedBy
,GETDATE()
from @MenuXml.nodes('/menuCollection/menuItem') AS menuList(row)
COMMIT TRANSACTION
RETURN 1
END TRY
BEGIN CATCH
ROLLBACK TRANSACTION
RETURN 0
END CATCH
更新可以借鉴上面的添加操作，
最近在工作中，经常设计报表（ireport+jasperReport）反复和设计模板xml打交道，于是就有了写这篇文章的想法了。java操作xml主要是有四种方式：dom，sax，jdom，dom4j。这四种方式各有优缺点：（以下比较是来自网络）
1：DOM4J性能最好，连Sun的JAXM也在用DOM4J.目前许多开源项目中大量采用DOM4J，例如大名鼎鼎的Hibernate ......
If XML data in the table is less than 32K for each record, then you can directly unload the data as char. If XML data exceeds 32K for some records, then you have to unload the common data and the XML data separately. First, create a template for unloading XML into a PDS: TEMPLATE LOBFRV DSN 'AAA. ......
