記事本++根據本地DTD驗證XML

Question

我有一個XML文件，我試圖根據DTD進行驗證（在與XML相同的本地文件夾中）。 XML檢出格式良好，但每次嘗試在記事本++中對DTD進行驗證都會導致「無法加載DTD PresidentsDTD.dtd」錯誤。任何想法我需要做些什麼來得到這個工作？

XML文件：

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

<LIST> 
<PRESIDENT id="01" gender="male" name="GeorgeWashington">

    <PARTY>Republican</PARTY>

</PRESIDENT> 
</LIST> 

我PresidentsDTD.dtd文件（在第2行還是返回一個錯誤出於某種原因）：

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

]> 

沒有人有驗證針對DTD本地的解決方案？

我編輯了你的XML和.dtd文件。現在XML是有效的。注意，在文件中，我添加了關於你的錯誤的評論。 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-->

     <TERM count="2"> 
      <TERMSTART>1789</TERMSTART> 
      <TERMEND>1797</TERMEND>

    <PRESIDENT id="ID07" gender="male" name="AndrewJackson">

    </PRESIDENT> 

    <PRESIDENT id="ID09" gender="male" name="WilliamHenryHarrison">

    <PRESIDENT id="ID15" gender="male" name="AbrahamLincoln">

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

如果從XML分別創建文件DTD架構，它不應該包含「[」]」你沒有界定黨和HOMESTATE你有錯誤的譯文定義屬性
。 PresidentsDTD.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>
