dtd文件中XML解析中的错误--“对与元素类型关联的属性”{1}预期为“打开引用.”

Question

我的address.dtd文件如下。当我试图使用address.xml解析SAXParserFactory文件时，异常如下：

"org.xml.sax.SAXParseException；systemId: org.xml.sax.SAXParseException lineNumber: 9；columnNumber: 22；对于与元素类型“省”相关联的属性“{1}，应使用开放引号。

<!-- address.dtd -->
<!ELEMENT address (name,house-id?,village,city,postal-code,country) >
<!ELEMENT name (personal:title*,(first-name|first-init),last-name+)>
<!ELEMENT house-id (houses:title,NAME)>
<!ELEMENT personal:name (#PCDATA) >
<!ELEMENT village (#PCDATA) >
<!ELEMENT city (#PCDATA) >
<!ATTLIST city district CDATA #REQUIRED 
               province CDATA (Southern|Western|Nothern|Eastern) "One Sri 
Lanka"> 
<!ELEMENT postal-code (#PCDATA) >
<!ELEMENT country (#PCDATA) >
<!ELEMENT personal:title (#PCDATA) >
<!ELEMENT first-name (#PCDATA) >
<!ELEMENT first-init (#PCDATA) >
<!ELEMENT last-name (#PCDATA) >
<!ELEMENT houses:title (#PCDATA) >
<!ELEMENT NAME (#PCDATA) >

address.xml文件如下所示。

<?xml version ="1.0" encoding="UTF-8"?>
<!DOCTYPE address SYSTEM "address.dtd">


<!-- Some namespaces are declared in this-->
<address 
    xmlns:personal="Personal things"
    xmlns:houses="Regarding to houses"

>
    <name  xml:space='preserve'>  
        <personal:title>Mr.     </personal:title>
        <first-name>Samitha       </first-name>
        <last-name>Chathuranga</last-name>
    </name>
    <house-id>
        <houses:title>107 B</houses:title>
        <NAME>Sam&apos;s Home</NAME>
        <!--  An intnal entity is used for the single quote in House Name here-->
    </house-id>
    <village>Poramba</village>
    <city district="Galle" province="Southern">AG</city>
    <postal-code>80300</postal-code>
    <country>Sri Lanka</country>
</address>

Answer 1

属性的数据类型可以是枚举或CDATA，但不能两者兼而有之。您应该删除CDATA

<!ATTLIST city 
      district CDATA #REQUIRED 
      province (Southern|Western|Nothern|Eastern) "One Sri Lanka">

然而，这里仍然存在一个问题。“一个斯里兰卡”的值与您在其中列出的四个值中的任何一个都不匹配。你在想什么？
