在網上找了些有關SQLXML與XSLT的文章，重新整理和調試了下。開發環境SQL2008，VS2010，SQLXML4.0可以從網上下載。測試數據庫用的是NorthWind，我下的是mdb,然後導入到SQL2008中的。
新建網站項目，安裝完SQLXML4.0後，添加引用，找到系統盤下\Program Files\SQLXML 4.0\bin\Microsoft.Data.SqlXml.dll. 添加完後，在web.config中就生成了這樣的語句：
<add assembly="Microsoft.Data.SqlXml, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845DCD8080CC91"/></assemblies>下面列出主要的代碼。
