  1. eEI-XML 教學

  2. Some rule of XML • All XML elements must have a closing tag <to>Tove <to>Tove</to> • XML tags are case sensitive <Message>This is incorrect</message> <Message>This is correct</Message> • All XML elements must be properly nested <aaa><bbb>this is incorrect</aaa></bbb> <aaa><bbb>this is correct</bbb></aaa>

  3. Some rule of XML • All XML documents must have a root element • With XML, white space is preserved <root> <child> <subchild>.....</subchild> </child></root>

  4. Some rule of XML • XML elements must follow these naming rules: • Names can contain letters, numbers, and other characters • Names must not start with a number or punctuation character • Names must not start with the letters xml (or XML or Xml ..) • Names cannot contain spaces

  5. 程式設計工具 • Microsoft Visual Studio 2005 • Microsoft Access 2003 (Office之後的版本，須另存成mdb檔)

  6. 建立Access資料庫 點擊兩下空白資料庫，新增一個資料庫

  7. 資料庫設計(新增資料表) 點擊此按鈕建立新資料表 點擊右鍵出現選單，選擇「檢視設計」後會跳出資料表名稱視窗，輸入名稱後點擊「確定」

  8. 資料庫設計(定義資料表) 輸入欄位名稱，定義資料類型

  9. 資料庫設計(資料表關聯設計) 點擊「資料庫關聯圖」，設計資料庫關聯

  10. 系統流程 Start 使用者登入 選擇購買產品 確定購買 輸入購買細節 進入購物清單 End 訂單資訊 輸出XML 讀取XML

  11. 系統畫面(登入) 輸入使用者帳號密碼後，點擊「登入」 使用資料表Account

  12. 系統畫面(產品清單) 資料庫關聯：「產品種類」對應到資料表Catalog內的CataID欄位

  13. 系統畫面(加入購物車) 點擊連結，將產品加入購物車內 選擇好要加入購物車產品後，點擊「進入購物清單」

  14. 系統畫面(訂購畫面) 輸入購買數量及交貨日期後，點擊「Buy」購買

  15. 系統畫面(訂單明細) 點擊XML檢視，產出XML資料交換格式

  16. 輸入的訂單資料

  17. 系統畫面(XML資料格式) 整張訂單範圍 訂單編號 使用者帳號 使用者姓名 訂購日期、交貨日期 購買產品清單 產品1及產品2 訂單總金額 交貨地址 聯絡電話

  18. 系統程式(XML字串產生語法) private void AssembleXML(string orderid, string[] productid, string[] product, string[] unitprice, string[] quan, string totalprice, string postcode, string address, string tel, string ordertime, string shippingtime) { string xmlstring = string.Empty; xmlstring = "<?xml version=\"1.0\" encoding=\"Big5\"?><Order><OrderID>" + orderid + "</OrderID><CustomerAccount>" + Session["Account"].ToString() + "</CustomerAccount><CustomerName>" + Session["AccountName"].ToString() + "</CustomerName><OrderDate>" + ordertime + "</OrderDate><ShippingDate>" + shippingtime + "</ShippingDate><BuyingProductList>"; for (int i = 0; i < product.Length; i++) { xmlstring += "<Product><ProductID>" + productid[i] + "</ProductID><ProductName>" + product[i] + "</ProductName><UnitPrice>" + unitprice[i] + "</UnitPrice><Quantity>" + quan[i] + "</Quantity></Product>"; } xmlstring += "</BuyingProductList><TotalPrice>" + totalprice + "</TotalPrice><ShippingAddress>" + postcode + " " + address + "</ShippingAddress><ContactTel>" + tel + "</ContactTel></Order>"; }

  19. 系統程式(XML字串寫入檔案語法) string xmlname = Session["Account"].ToString()+ "_" + orderid; string strFilePath = HttpContext.Current.Server.MapPath("~/orderXML/" + xmlname + ".xml").ToString(); string strFile = xmlstring; using (System.IO.FileStream fs = new System.IO.FileStream(strFilePath, System.IO.FileMode.OpenOrCreate, System.IO.FileAccess.Write, System.IO.FileShare.ReadWrite)) { using (System.IO.StreamWriter fileWrite = new System.IO.StreamWriter(fs, System.Text.Encoding.GetEncoding(950))) { fileWrite.Write(strFile); fileWrite.Flush(); } }

  20. 讀取XML檔 串聯XSL與HTML之頁面 XslCompiledTransform transform = new XslCompiledTransform(); transform.Load(Server.MapPath("order.xsl")); transform.Transform(Server.MapPath("orderXML/Customer.xml"), Server.MapPath("a.html")); Response.WriteFile(Server.MapPath("a.html"));

  21. XSLT example <?xml version="1.0" encoding="ISO-8859-1"?><xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="/"> <html> <body> <h2>My CD Collection</h2> <table border="1"> <trbgcolor="#9acd32"> <th align="left">Title</th> <th align="left">Artist</th> </tr> <xsl:for-eachselect="catalog/cd"> <tr> <td><xsl:value-of select="title"/></td> <td><xsl:value-of select="artist"/></td> </tr> </xsl:for-each> </table> </body> </html> </xsl:template></xsl:stylesheet> • XML • <?xml version="1.0" encoding="ISO-8859-1"?> • <?xml-stylesheet type="text/xsl" href="cdcatalog.xsl"?> • <catalog> • <cd> • <title>Empire Burlesque</title> • <artist>Bob Dylan</artist> • <country>USA</country> • <company>Columbia</company> • <price>10.90</price> • <year>1985</year> • </cd> • . • . • . • </catalog>

  22. XSLT example

  23. Homework • 以每組為單位 • 寫出一範例產出XML檔 • 解釋所產出的XML檔內容 • 使用XSL讀取所產出的XML檔並顯示 • 繳交日期：Income報告完

  24. THANK YOU!
