问题

I have two xml files. and I want to refer the value of a node from the other xml file.

example: 1.xml

<?xml version="1.0"?>

   </book>
</catalog>

an 2.xml is

<?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>

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>

Can I get some help in resolving the issue.

Thanks

Use a dummy stylesheet to resolve the error:

<?xml-stylesheet href="http://www.w3.org/StyleSheets/TR/W3C-REC.css"?>

Use a DTD to declare the ID attributes of the book elements as type ID:

<!ATTLIST book id ID #IMPLIED>

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">
