Notepad++ 根据本地 DTD 验证 XML答案

【问题标题】：Notepad++ validating XML against local DTDNotepad++ 根据本地 DTD 验证 XML
【发布时间】：2015-12-24 22:20:58
【问题描述】：

我有一个 XML 文件，我正在尝试针对 DTD 进行验证（在与 XML 相同的本地文件夹中）。 XML 以格式正确的方式检出，但每次尝试在 notepad++ 中针对 DTD 进行验证都会导致“无法加载 DTD PresidentsDTD.dtd”错误。知道我需要做什么才能使其正常工作吗？

XML 文件：

<?xml version="1.0" standalone="no"?>
<!DOCTYPE LIST SYSTEM "PresidentsDTD.dtd">

<LIST>
<PRESIDENT id="01" gender="male" name="GeorgeWashington">
    <NAME>
        <FIRST>George</FIRST>

    </TERM>
    <PARTY>Republican</PARTY>
    <HOMESTATE>Illinois</HOMESTATE>
</PRESIDENT>
</LIST>

我的 PresidentsDTD.dtd 文件（由于某种原因仍然在第 2 行返回错误）：

<!DOCTYPE LIST[
<!ELEMENT LIST PRESIDENT+>
<!ELEMENT PRESIDENT (NAME, TERM, PARTY, HOMESTATE)>
<!ATTLIST PRESIDENT id ID #REQUIRED>

<!ELEMENT TERMLENGTH (#PCDATA)>
<!ATTLIST TERMLENGTH unit (months | years) #IMPLIED>
]>

有没有人有针对本地 DTD 进行验证的解决方案？

【解决方案1】：

我编辑了您的 XML 和 .dtd 文件。现在 XML 是有效的。请注意，在文件中，我在您的错误上添加了 cmets。 XML 文件：

<?xml version="1.0" standalone="no"?>
    <!DOCTYPE LIST SYSTEM "PresidentsDTD.dtd">
    <LIST>
    <PRESIDENT id="ID01" gender="male" name="GeorgeWashington"> <!--id must be unique-->

    </LIST>

如果您从 XML 中单独创建文件 DTD 架构，则它不应包含“[”]“。您没有定义 PARTY 和 HOMESTATE。您在 PRESIDENT 中定义了错误的属性。
总统DTD.dtd：

<!ELEMENT LIST (PRESIDENT+)>

<!ELEMENT PRESIDENT (NAME, TERM, PARTY, HOMESTATE)>

<!ELEMENT NAME (FIRST, MIDDLE?, LAST)>
<!ELEMENT FIRST (#PCDATA)>
<!ELEMENT MIDDLE (#PCDATA)>
<!ELEMENT LAST (#PCDATA)> 

<!ELEMENT TERM (TERMSTART, TERMEND, TERMLENGTH)>
<!ELEMENT TERMSTART (#PCDATA)>
<!ELEMENT TERMEND (#PCDATA)>
<!ELEMENT TERMLENGTH (#PCDATA)>

<!ELEMENT PARTY (#PCDATA)>
<!ELEMENT HOMESTATE (#PCDATA)>


<!ATTLIST PRESIDENT 
            id ID #REQUIRED 
            gender (male | female) #IMPLIED 
            name CDATA #IMPLIED>
<!ATTLIST TERM 
            count CDATA #IMPLIED>
<!ATTLIST TERMLENGTH 
            unit (months | years) #IMPLIED>
