王豐緒銘傳大學資工系

單元目標

練習 XSL 程式的撰寫› 了解 XSL 的轉換意義

XML 文件中宣告 XSL

在 XML 文件中宣告 XSL› <?xml-stylesheet type=”text/xsl” href=“ 檔案位

址” ?>

<?xml version=“1.0” ?><?xml-stylesheet type=“text/xsl” href=“test.xsl” ?><booklist> <book> <author>fhwang</author> <title>XML Programming</title> <chatpers>10</chapters> </book></booklist>

如何撰寫 XSL 程式

務必先了解 XSL 的運作原理了解題目所給 XML 文件的結構了解所欲轉換成的結果 ( 如 HTML 網頁 ) 分析 XML 與轉換結果的對應關係撰寫 XSL 的對應轉換規則測試 - 除錯 - 修改 - 直到完成
