內嵌DTD與構建

Question

我將如何建立這個......

<!DOCTYPE root-element[ 
    <!ENTITY % w3centities PUBLIC 
    "-//W3C//ENTITIES Combined Set//EN//XML" 
    "w3centities.ent" 
    > 
    %w3centities; 
]> 

...使用生成器？

我可以管理除了「％w3centities」以外的每一個人;在第二與下面的代碼行持續：

xml.declare! :DOCTYPE, "root-element" do 
    xml.declare! :ENTITY, "%", :w3entities, :PUBLIC, 
    "-//W3C//ENTITIES Combined Set//EN//XML", 
    "w3centities.ent" 
end 

感謝

Answer 1

這裏就是我做得到它的工作...

xml.target! << "<!DOCTYPE root-element[ 
    <!ENTITY % w3centities PUBLIC 
    \"-//W3C//ENTITIES Combined Set//EN//XML\" 
    \"w3centities.ent\" 
    > 
    %w3centities; 
]>"
