Question

尽管存在根元素并且已经在DTD的ATTLIST中插入了所有属性，但是我在w3验证器上出现了几个错误：

错误第17行，第9列：声明中不允许使用字符“g”   子集gender CDATA #REQUIRED>

错误第21行，第45栏：没有属性“性别”    ...... <person user="WhozYourDaddy" gender="male" email="whozyourdaddy@gmail.com">

错误第21行，第58栏：没有属性“email”... <person user="WhozYourDaddy" gender="male" email="whozyourdaddy@gmail.com">

错误第29行，第22列：文档类型不允许使用元素   “lastdownload”在这里           <lastdownload> PokemonGo </lastdownload>

错误第30行，第19列：文档类型不允许使用元素   “lastlogin”在这里           <lastlogin> 12.03.2016 </lastlogin>

这是我的XML：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE catalog [
<!ELEMENT catalog (person+)>
<!ELEMENT person (firstname,lastname,telephone,city,address, preferences, newsletter, downloads)>
<!ELEMENT firstname (#PCDATA)>

        <lastlogin> 12.03.2016 </lastlogin>
        <downloads> 5 </downloads>
    </person>
</catalog>

Answer 1

要解决几个错误：

ATTLIST

将lastdownload和lastlogin添加到catalog的内容模型。

以下是适用所有修补程序的XML：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE catalog [
<!ELEMENT catalog (person+)>
<!ELEMENT person (firstname,lastname,telephone,city,address, preferences,
