我们紧接着上篇，继续xls xlst xml
-----------------------------------我是华丽的分割线-----------------------------------------
11.先看简单的代码
XML文件：
<?xml version="1.0" encoding="utf-8" ?>
<?xml-stylesheet type="text/xsl" href="hello.xslt"?>
<message>Hello,world!</message>
Xlst文件：
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl"
>
<xsl:output method="xml" indent="yes"/>
<xsl:template match="/">
<html>
<body>
<h1>
<xsl:value-of select="message"/>
</h1>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
效果如图：
12.先准备xml文件
xml文件如下：
View Code
<?xml version="1.0" encoding="utf-8" ?> <?xml-stylesheet type="text/xsl" href="Products.xslt"?> <Products> <Category Name="笔记本"> <Product ProductID="100"> <ProductName>联想</ProductName> <ProductNumber>SB-M1911</ProductNumber> <Cost>2000</Cost> <Price>4000</Price> </Product> <Product ProductID="200"> <ProductName>神舟</ProductName> <ProductNumber>SZ-M1911</ProductNumber> <Cost>1000</Cost> <Price>2000</Price> </Product> <Product ProductID="300"> <ProductName>惠普</ProductName> <ProductNumber>HP-M1911</ProductNumber> <Cost>3000</Cost> <Price>5000</Price> </Product> </Category> <Category Name="数码相机"> <Product ProductID="600"> <ProductName>尼康</ProductName> <ProductNumber>NK-M000</ProductNumber> <Cost>2000</Cost> <Price>4000</Price> </Product> <Product ProductID="700"> <ProductName>索尼</ProductName> <ProductNumber>SN-M1911</ProductNumber> <Cost>1000</Cost> <Price>2000</Price> </Product> <Product ProductID="800"> <ProductName>松下</ProductName> <ProductNumber>SX-M1911</ProductNumber> <Cost>3000</Cost> <Price>5000</Price> </Product> </Category> </Products>
13.使用 xsl:for-each 的xlst
View Code
<?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl" > <xsl:output method="xml" indent="yes"/> <xsl:template match="/"> <table style="background-color:lightgreen"> <xsl:for-each select="./Products/Category"> <tr> <td style="border:solid 1px black;"> <xsl:value-of select="./@Name"/> </td> </tr> </xsl:for-each> </table> </xsl:template> </xsl:stylesheet>
效果如下：

效果如下：
18.要实现如下图所示的功能，有三种xslt写法
方法一：使用嵌套的xsl:for-each
View Code
<?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl" > <xsl:output method="xml" indent="yes"/> <xsl:template match="/"> <table> <xsl:for-each select="./Products/Category"> <tr> <td style="border:solid 1px black;"> <xsl:value-of select="@Name"/> </td> <td style="border:solid 1px black;"> <ul> <xsl:for-each select="./Product"> <li> <xsl:value-of select="@ProductID"/> <xsl:value-of select="ProductName"/> </li> </xsl:for-each> </ul> </td> </tr> </xsl:for-each> </table> </xsl:template> </xsl:stylesheet>
方法二：使用xsl:apply-templates 路径
View Code
<?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl" > <xsl:output method="xml" indent="yes"/> <xsl:template match="/"> <table> <xsl:for-each select="./Products/Category"> <tr> <td style="border:solid 1px black;"> <xsl:value-of select="@Name"/> </td> <td style="border:solid 1px black;"> <xsl:apply-templates select="."></xsl:apply-templates> </td> </tr> </xsl:for-each> </table> </xsl:template> <xsl:template match="Category"> <ul> <xsl:for-each select="./Product"> <li> <xsl:value-of select="@ProductID"/> <xsl:value-of select="ProductName"/> </li> </xsl:for-each> </ul> </xsl:template> </xsl:stylesheet>
方法三：使用xsl:apply-templates name
View Code
<?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl" > <xsl:output method="xml" indent="yes"/> <xsl:template match="/"> <table> <xsl:for-each select="./Products/Category"> <tr> <td style="border:solid 1px black;"> <xsl:value-of select="@Name"/> </td> <td style="border:solid 1px black;"> <xsl:call-template name="C"></xsl:call-template> </td> </tr> </xsl:for-each> </table> </xsl:template> <xsl:template match="Category" name="C"> <ul> <xsl:for-each select="./Product"> <li> <xsl:value-of select="@ProductID"/> <xsl:value-of select="ProductName"/> </li> </xsl:for-each> </ul> </xsl:template> </xsl:stylesheet>
19.使用.Net中的xlst功能
a)从工具箱中,拖一个xml控件,如图:
设置xml控件的属性:
这样效果,和18图一样
b)通过代码的方式:
View Code
public static string GetString(string path) { /* * select top 5 SalesLT.ProductCategory.Name "Category/@Name", ProductID "Category/Product/@ProductID", SalesLT.Product.Name "Category/Product/ProductName", ProductNumber "Category/Product/ProductNumber", StandardCost "Category/Product/Cost", ListPrice "Category/Product/Price" from SalesLT.Product join SalesLT.ProductCategory on SalesLT.Product.ProductCategoryID=SalesLT.ProductCategory.ProductCategoryID for xml path(''),root('Products') */ string sql = @"select top 5 SalesLT.ProductCategory.Name ""Category/@Name"", ProductID ""Category/Product/@ProductID"", SalesLT.Product.Name ""Category/Product/ProductName"", ProductNumber ""Category/Product/ProductNumber"", StandardCost ""Category/Product/Cost"", ListPrice ""Category/Product/Price"" from SalesLT.Product join SalesLT.ProductCategory on SalesLT.Product.ProductCategoryID=SalesLT.ProductCategory.ProductCategoryID for xml path(''),root('Products')"; SqlConnection conn = new SqlConnection("Data Source=Refactor;Initial Catalog=AdventureWorksLT;user id=sa;pwd=a123456"); SqlCommand cmd = new SqlCommand(sql, conn); conn.Open(); XmlReader reader = cmd.ExecuteXmlReader(); reader.Read(); string s = reader.ReadOuterXml(); reader.Close(); conn.Close(); XmlDocument doc = new XmlDocument(); doc.LoadXml(s); XslCompiledTransform ct = new XslCompiledTransform(); ct.Load(path); System.IO.MemoryStream ms = new System.IO.MemoryStream(); ct.Transform(doc, null, ms); return Encoding.UTF8.GetString(ms.ToArray()); }
