String doctyperegex = "^(<!DOCTYPE)";
Pattern doctypepattern = Pattern.compile(doctyperegex, Pattern.CASE_INSENSITIVE);
Matcher doctypematcher = doctypepattern.matcher(aline);
while(doctypematcher.find())
{
System.out.println(aline);
aline = "<!DOCTYPE html>";
System.out.println(aline);
}
先宣告一個正規表達式的字串，名稱為doctyperegex，先將"<!DOCTYPE"這個字串開頭的程式碼找出來，我們只管"<!DOCTYPE"開頭的就可以，後面接什麼東西並不重要，接著把那整句進行取代成"<!DOCTYPE html>"，這樣就完成了DOCTYPE的轉換，很簡單吧。同樣的<meta>標籤內容的轉換也是一樣，程式碼片段如下所示：String metaregex = "^(<meta)";
Pattern metapattern = Pattern.compile(metaregex, Pattern.CASE_INSENSITIVE);
Matcher metamatcher = metapattern.matcher(aline);
while(metamatcher.find())
{
System.out.println(aline);
aline = "<meta charset=UTF-8>";
System.out.println(aline);
}
道理一樣囉~就參考看看吧!那...這次就先寫到這，接下來還有許多標籤的轉換規則要研究，我還在努力中呢...
