代码应该是这样的吗?
<!ATTLIST review then i don't really know how the syntax goes.
答案 0 :(得分:0)
可能是这样的:
<!ATTLIST review rating NMTOKEN #REQUIRED>
<!ATTLIST review reviewer CDATA #REQUIRED>
或
<!ATTLIST review rating NMTOKEN #REQUIRED>
reviewer CDATA #REQUIRED>
语法(对于一个属性)是:
<!ATTLIST element-name attribute-name attribute-type attribute-usage>
数字通常是NTOKEN
(不允许空格或特殊字符)和字符串CDATA
。您还可以枚举NMTOKENS (option1 | option2)
。属性类型也可以是#IMPLIED
(可选),#FIXED "value"
,默认值"value"
。
