问题描述

xml中关于外部实体的问题

 <?xml version="1.0" encoding="gb2312" ?>
<!DOCTYPE volume SYSTEM "D:xmlMuseum.dtd"[
    <!ENTITY Oldcoinses SYSTEM "D:xmlOldcoins.xml">
    <!ENTITY Oilpaintings SYSTEM "D:xmlOilpainting.xml">
    <!ENTITY Sculptures SYSTEM "D:xmlSculpture.xml">
]>
<volume>
&Oilpaintings;
&Oldcoinses;
&Sculptures;
</volume>

上面代码运行后出现错误：
This page contains the following errors:

error on line 3 at column 49: Invalid URI: D:xmlOldcoins.xml
error on line 4 at column 54: Invalid URI: D:xmlOilpainting.xml
error on line 5 at column 50: Invalid URI: D:xmlSculpture.xml
error on line 8 at column 15: Entity 'Oilpaintings' failed to parse
Below is a rendering of the page up to the first error.

刚接触这xml不懂，点拨一下，谢谢

解决方案

xml的DOCTYPE怎么会使用本地的dtd呢，
以前很少人这么做，你应该是自己想测试dtd
D:/xml/Oldcoins.xml
file:///D:/xml/Oldcoins.xml
看看这样行不行
