java - XML解析错误: The markup declarations contained or pointed to by the document type declaration must be well-formed

Question

我有一个 XML 文档，如下所示:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE IMPORTANT_DAYS PUBLIC "-//XYZ//DTD Declarations(ImportantDays)//EN" "dtds/important_days.dtd">
<IMPORTANT_DAYS>
    <MONTH name="January">
        <DAY    date="9"    occassion="NRI Day"/>
        <DAY    date="10"   occassion="World Laughter Day"/>
        <DAY    date="12"   occassion="National Youth Day"/>
        <DAY    date="15"   occassion="Army Day"/>
        <DAY    date="25"   occassion="National Tourism Day"/>
        <DAY    date="26"   occassion="Republic Day Of India;International Customs Day"/>
        <DAY    date="30"   occassion="Martyr's Day;World Leprosy Day"/>
    </MONTH>
</IMPORTANT_DAYS>

以下 DTD 文件名为 - important_days.dtd:

<!ELEMENT IMPORTANT_DAYS (MONTH+)>
<!ELEMENT MONTH (DAY+)>
<!ELEMENT DAY EMPTY>
<!ATTLIST MONTH name NMTOKEN #REQUIRED>
<!ATTLIST DAY date NMTOKEN #IMPLIED>
<!ATTlIST DAY count NMTOKEN #IMPLIED>
<!ATTlIST DAY day NMTOKEN #IMPLIED>
<!ATTLIST DAY occassion CDATA #REQUIRED>

当我尝试解析 XML 文件时，我在“important_days.dtd”中的第 6 行收到以下错误:

6:The markup declarations contained or pointed to by the document type declaration must be well-formed.

谁能指出问题所在吗？

Answer 1

XML 区分大小写。注意小写的 L 字符，它应该是大写的:

Line 6: <!ATTlIST DAY count NMTOKEN #IMPLIED>
             ^

Line 7: <!ATTlIST DAY day NMTOKEN #IMPLIED>
             ^
