求XML解析成HTML的代码，支持嵌套！

[ttyp]

需要把元素全部转换成服务端的控件

[BearRui]

利用XSL，可以参考CSDN本身的例子：

http://community.csdn.net/expert/Xsl/2.xsl

[ttyp]

XSL可以实现服务端的么？

[saucer]

what is your purpose? if you need to create controls on the fly based on an xml file, use a XmlTextReader, for example, if you have

...

<control type="textbox" Text="abc" />
<control type="button" Text="abc" />
...

you could do something like (pseudo code)

XmlTextReader xtr = new XmlTextReader(....);
while (xtr.Read())
{
if (xtr.NodeType == XmlNodeType.Element)
{
if (xtr.LocalName == "control")
{
Control c = null;
switch(xtr.GetAttribute("type"))
{
case "textbox":

c = new TextBox();
break;

case "button":

c = new Button();
break;

}

if (c != null)
form1.Controls.Add(c);


}
}
}

我要做自定义的表单，用XML定义HTML元素，最后取HTML的元素中内容提交，涉及到TABLE排版，TextBox控件和DropDownList控件等

[ttyp]

to saucer(思归):要支持嵌套，好象要麻烦点

[saucer]

same idea, just keep the parent control around, or use a stack to keep track of controls created

[ttyp]

就是这没想明白，给点提示

[happyjun2000]

用xsl来处理，网上找点资料。

[saucer]

show an example of XML, we will show you a way

[ttyp]

<?xml version="1.0" encoding="GB2312"?>
<form>
<table>
<tr>
<td>
<label>请假人</label>

<text field="a" name="proposer" width="100" height="20" multiLine="false" validation="" validation_name="" example="" max_len="10" can_be_null="false" >

it is ugly, you could use Reflection to use less methods, but performance could be an issue, try something like (you need to fill the rest for other controls):

<%@ Import Namespace="System.IO" %>
<%@ Import Namespace="System.Xml" %>
<script language="C#" runat="server">
void Page_Load(Object sender, EventArgs e)
{
string sFile = Server.MapPath("form.xml");
StreamReader sr = new StreamReader(sFile, System.Text.Encoding.GetEncoding("GB2312"));
XmlTextReader xtr = new XmlTextReader(sr);
ProcessReader(xtr);
sr.Close();
}

void ProcessReader(XmlTextReader reader)
{
while (reader.Read())
{
if (reader.NodeType == XmlNodeType.Element && reader.LocalName.ToLower() == "form")
{
ProcessForm( reader, Page);
}
}
}

void ProcessForm(XmlTextReader reader, Page p)
{
HtmlForm hf = new HtmlForm();
hf.ID = "form1";
p.Controls.Add(hf);

ProcessChildren(reader, hf, "form");
}


void ProcessTable(XmlTextReader reader, Control cParent)
{
Table t = new Table();
cParent.Controls.Add(t);

ProcessChildren(reader, t, "table");
}


void ProcessTR(XmlTextReader reader, Table t)
{
TableRow tr = new TableRow();
t.Rows.Add(tr);

ProcessChildren(reader,tr, "tr");
}


void ProcessTD(XmlTextReader reader, TableRow tr)
{
TableCell td = new TableCell();
tr.Cells.Add(td);

ProcessChildren(reader, td, "td");
}

void ProcessLabel(XmlTextReader reader, Control c)
{
Label l = new Label();
c.Controls.Add(l);
l.Text = reader.ReadString();
}

void ProcessText(XmlTextReader reader, Control c)
{
TextBox tb = new TextBox();
tb.ID = reader.GetAttribute("name");
if (reader.GetAttribute("multiLine").ToLower()=="true")
tb.TextMode = TextBoxMode.MultiLine;
c.Controls.Add(tb);

//ProcessChildren(reader, tb, "text");
}

void ProcessChildren(XmlTextReader reader, Control c, string strParentTagName)
{
while (reader.Read())
{
if (reader.NodeType == XmlNodeType.EndElement && reader.LocalName.ToLower() == strParentTagName)
return;

if (reader.NodeType == XmlNodeType.Element)
{
string str = reader.LocalName.ToLower();
switch(str)
{
case "text":
ProcessText(reader, c);
break;

case "label":
ProcessLabel(reader, c);
break;

case "table":
ProcessTable(reader, c);
break;

case "tr":
ProcessTR(reader, (Table)c);
break;

case "td":
ProcessTD(reader, (TableRow)c);
break;

}
}
}
}
</script>

谢谢老大(f),反正用反射更简单,顺便也写个吧,我好整理下帖出来:)

xslt有循环语法
