一个 2.xml 是
<?xml version="1.0" encoding="ISO-8859-1"?>
<doc xmlns:xi="http://www.w3.org/2003/XInclude">
<xi:include href="1.xml" xpointer="bk101"/>
</doc>
当我执行 2.xml 时，我收到一条错误消息此 XML 文件似乎没有任何与之关联的样式信息.文档树如下所示.
When I execute 2.xml, I get a error saying This XML file does not appear to have any style information associated with it. The document tree is shown below.
<doc><xi:include href="book.xml" xpointer="bk101"/></doc>
我能得到一些帮助来解决这个问题吗.
Can I get some help in resolving the issue.
谢谢
推荐答案
使用虚拟样式表解决错误:
Use a dummy stylesheet to resolve the error:
<?xml-stylesheet href="http://www.w3.org/StyleSheets/TR/W3C-REC.css"?>
使用 DTD 将 book 元素的 ID 属性声明为类型 ID:
Use a DTD to declare the ID attributes of the book elements as type ID:
<!ATTLIST book id ID #IMPLIED>
将其另存为ids.dtd，然后使用1.xml 中的文档类型来引用它:
Save it as something like ids.dtd, then use a doctype in 1.xml to reference it:
<?xml version="1.0"?>
<!DOCTYPE id-list SYSTEM "ids.dtd">
