我们首先添加一个目录XML。然后添加View:
1.checkXml.aspx 用来检查我们输入的XML格式（利用XSD检查）
2.New.aspx 用来新增XML表单的
3.Show.aspx 用来显示XML表单的
4.ShowResult.aspx 用来显示XML表单提交的结果的
一、数据库结构
要用到动态的表单，这里我们利用Sqlserver2005的XML类型来保存，建表的SQL如下：
use Test
/*==============================================================*/
/* DBMS name: Microsoft SQL Server 2005 */
/* Created on: 2009/5/8 7:56:50 */
/*==============================================================*/
if exists (select 1
from sysindexes
where id = object_id('XMLFORM')
and name = 'IDX_XML'
and indid > 0
and indid < 255)
drop index XMLFORM.IDX_XML
go
if exists (select 1
from sysindexes
where id = object_id('XMLFORM')
and name = 'IDX_ID'
and indid > 0
and indid < 255)
drop index XMLFORM.IDX_ID
go
if exists (select 1
from sysobjects
where id = object_id('XMLFORM')
and type = 'U')
drop table XMLFORM
go
/*==============================================================*/
/* Table: XMLFORM */
/*==============================================================*/
create table XMLFORM (
ID int identity,
FORMXML xml not null,
constraint PK_XMLFORM primary key (ID)
)
go
declare @CurrentUser sysname
select @CurrentUser = user_name()
execute sp_addextendedproperty 'MS_Description',
'XMLFORM',
'user', @CurrentUser, 'table', 'XMLFORM'
go
/*==============================================================*/
/* Index: IDX_ID */
/*==============================================================*/
create unique index IDX_ID on XMLFORM (
ID ASC
)
go
/*==============================================================*/
/* Index: IDX_XML */
/*==============================================================*/
create PRIMARY XML INDEX IDX_XML on XMLFORM (
FORMXML
)
go
好了我们建了一个名为XMLForm的表，其中ID自增，FORMXML为我们需要的XML表单的内容
二、编写XML的Controller
XMLController.cs
主要的action
1.New
[AcceptVerbs(HttpVerbs.Post), ValidateInput(false)]
public ActionResult New(string xmlContent)
{
System.Threading.Thread.Sleep(2000); //模拟提交等待
xmlContent = Server.UrlDecode(xmlContent);
if (!string.IsNullOrEmpty(xmlContent))
{
//if (!CheckXML(xmlContent, out strError)) //服务器端检测，如果用了ajax检测，就没必要了
//{
// ModelState.AddModelError("_FORM",strError);
// return View();
//}
XMLFormDataContext db = new XMLFormDataContext();
TransactionOptions opt = new TransactionOptions();
ViewData["xmlContent"] = xmlContent;
opt.IsolationLevel = IsolationLevel.Serializable;
using (TransactionScope tran = new TransactionScope(TransactionScopeOption.RequiresNew, opt))
{
XMLFORM f = new XMLFORM();
try
{
f.FORMXML = XElement.Parse(xmlContent);
db.XMLFORMs.InsertOnSubmit(f);
db.SubmitChanges();
var id = db.XMLFORMs.Max(p => p.ID);
ViewData["result"] = "success";
ViewData["id"] = (int)id;
tran.Complete();
return View();
}
catch
{
ViewData["result"] = "failure";
ModelState.AddModelError("_FORM", "envalid xml format");
return View();
}
}
}
else
return View();
}
XML：
注意：我们使用了事务，所以不要忘了最后要提交。我就是忘了，找了3天错误
2.Show
[AcceptVerbs(HttpVerbs.Get)]
public ActionResult Show(int? ID)
{
int nId = 0;
XElement doc = null;
if (int.TryParse(Request["id"], out nId))
{
try
{
XMLFormDataContext db = new XMLFormDataContext();
var q = from f in db.XMLFORMs
where f.ID == nId
select f.FORMXML
;
if (q.Count() > 0)
{
foreach (var qq in q)
{
doc = qq;
}
ViewData["xml"] = doc;
}
else
{
ModelState.AddModelError("_FORM", "Not Exists");
}
ViewData["id"] = nId;
}
catch (Exception e)
{
ModelState.AddModelError("_FORM", e.Message);
}
}
else
{
ModelState.AddModelError("_FORM", "Miss ID");
}
return View();
}
注意这里Show.asp的写法.不能用直接输出控件字符串，而要
Response.Write(Html.TextBox(i.Attribute("Name").Value, "", new { @class = "InputNormal" }));
否则提交后得不到form的值
代码如下：
<%using (Html.BeginForm())
{ %>
<%=Html.ValidationSummary()%>
dicResult = new Dictionary();
dicResult.Add("State", nResult.ToString());
dicResult.Add("Message", strOut);
return Json(dicResult);
}
private bool CheckXML(string xmlContent)
{
bool bResult = true;
if (!string.IsNullOrEmpty(xmlContent))
{
//利用XmlSchemaSet(XSD)检查XML
XmlSchemaSet validator = new XmlSchemaSet();
validator.Add("", XmlReader.Create(Server.MapPath(Url.Content("~/Models/xmlTest.xsd")))); //Url.Content必须，否则找不到文件
XDocument doc = null;
try
{
doc = XDocument.Parse(xmlContent);
doc.Validate(validator, (sender, e) =>
{
bResult = false;
});
}
catch
{
bResult = false;
}
}
else
bResult = false;
return bResult;
}
private bool CheckXML(string xmlContent, out string outString)
{
bool bResult = true;
string strError = string.Empty;
if (!string.IsNullOrEmpty(xmlContent))
{
//利用XmlSchemaSet(XSD)检查XML
XmlSchemaSet validator = new XmlSchemaSet();
validator.Add("", XmlReader.Create(Server.MapPath(Url.Content("~/Models/xmlTest.xsd")))); //Url.Content必须，否则找不到文件
XDocument doc = null;
try
{
doc = XDocument.Parse(xmlContent);
doc.Validate(validator, (sender, e) =>
{
strError = e.Message;
bResult = false;
});
}
catch (XmlException e)
{
strError = e.Message;
bResult = false;
}
}
else
bResult = false;
if (!bResult)
outString = strError;
else
outString = "OK";
return bResult;
}
#endregion
这里我们返回json数据，来ajax检查
$(document).ready(function() {
$("form").submit(function() {
if (jQuery.formValidator.pageIsValid())
$.blockUI({ message: '
