一、ＵＩ层处理：
#region 重新生成手机服务栏目列表XML
private void CreateMetoneTree()
{
xmlDoc_Metone = new XmlDocument();
new Town.Com.MobileServiceTypeCollection().GetMetoneTree(out ds);
//生成根节点
XmlElement treeContentElement = xmlDoc_Metone.CreateElement("NewDataSet");
xmlDoc_Metone.AppendChild(treeContentElement);
//递归生成频道的XML文档
for(int j=0;j<ds.Tables["Tree"].Rows.Count;j++)
{
if(Int32.Parse(ds.Tables["Tree"].Rows[j].ItemArray[2].ToString()) == 0)
{
this.BulidXmlTree(treeContentElement,j);
}
else
{
continue;
}
}
string fileName = Server.MapPath("Xml/MetoneTree.xml");
xmlDoc_Metone.Save(fileName);
}
#endregion
#region 构XML树
private void BulidXmlTree(XmlElement tempXmlElement,int location)
{
DataRow tempRow = ds.Tables["Tree"].Rows[location];
//生成Tree节点
XmlElement treeElement = xmlDoc_Metone.CreateElement("Tree");
tempXmlElement.AppendChild(treeElement);
this.AppendChildElement("MetoneID",tempRow.ItemArray[0].ToString(),treeElement);
this.AppendChildElement("MetoneName",tempRow.ItemArray[1].ToString(),treeElement);
this.AppendChildElement("ParentMetoneID",tempRow.ItemArray[2].ToString(),treeElement);
this.AppendChildElement("MetoneUrl",tempRow.ItemArray[3].ToString(),treeElement);
for(int i=0 ; i < ds.Tables["Tree"].Rows.Count;i++)
{
if(ds.Tables["Tree"].Rows[i].ItemArray[2].ToString() == tempRow.ItemArray[0].ToString())
{
this.BulidXmlTree(treeElement,i);
}
}
}
#endregion
#region 追加子节点

private void AppendChildElement(string strName , string strInnerText , XmlElement parentElement, XmlDocument xmlDocument )
{
XmlElement xmlElement = xmlDocument.CreateElement(strName) ;
xmlElement.InnerText = strInnerText ;
parentElement.AppendChild(xmlElement);
}

AppendChildElement(strName,strInnerText,parentElement,xmlDoc_Metone);
}
#endregion
一点说明：感觉这些代码基本上都是自解释的，关键点都有注释，看看就明白的。
二、解析ｘｍｌ的ｘｓｌｔ
<?xml version="1.0" encoding="gb2312"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="gb2312" indent="yes"/>
<xsl:template match="NewDataSet">
<xsl:apply-templates select="Tree"></xsl:apply-templates>
</xsl:template>
<xsl:template match="Tree">
<div ondragstart="return false" style="padding-left:20px;" >
<xsl:attribute name="onclick">selectedEntity = '<xsl:value-of select="MetoneID" />';clickOnEntity(this);redirect('<xsl:value-of select="MetoneUrl" />');</xsl:attribute>
<xsl:attribute name="open">false</xsl:attribute>
<xsl:attribute name="id">
<xsl:value-of select="MetoneID" />
</xsl:attribute>
<xsl:attribute name="STYLE">
<xsl:if test="count(ancestor::node()) > 2">
display: none;
</xsl:if>
cursor: hand;
</xsl:attribute>
<table border="0" cellpadding="0" cellspacing="0" style="line-height:130%">
<tr>
<td >
<a href="{MetoneUrl}" target="main"><xsl:value-of select="MetoneName"></xsl:value-of></a>
</td>
</tr>
</table>
<xsl:apply-templates select="Tree"></xsl:apply-templates>
</div>
</xsl:template>
</xsl:stylesheet>
三、一个小技巧：用ｊｓ把ｘｍｌ的数据用ｘｓｌｔ解析后填充到固定的ｈｔｍｌ块中，比如ｄｉｖ，调用代码：initAdmin('MetoneTree.xml', 'submenu','MetoneTree.xslt')，ｊｓ代码如下：
var view;//中英文版本切换
var xmlDoc;//MSXML2.DOM对象
var selectedEntity;//选中接点ID号
function initAdmin(fileName, divTree,xsltFile, expID)//初始化树状结构
{
var xslDoc;
var strXml;
var objXml;
var xmlHttp;
var xslProc;
var xslTemplate;
//alert(fileName);
xmlDoc = new ActiveXObject("MSXML2.DOMDocument");
xmlDoc.async = false;
xslDoc = new ActiveXObject("MSXML2.FreeThreadedDOMDocument");
xslDoc.async = false;
xmlDoc.load("XML/"+fileName);
xslDoc.load("XSLT/"+xsltFile);
xslTemplate = new ActiveXObject("MSXML2.XSLTemplate");
xslTemplate.stylesheet = xslDoc;
xslProc = xslTemplate.createProcessor();
xslProc.input = xmlDoc;
xslProc.transform();
document.all[divTree].innerHTML = xslProc.output;
if(expID != null)
{
expandSome(document.all[expID]);
}
}
