xmlns declarations broken over multiple elements, "global" scope

I want to break the xmlns declarations into multiple lines. I've seen it in text books, but when I try to replicate it, [shell-tools][1] gives an error for the second example below:

/var/tmp/FOO758cqr:11: parser error : Premature end of data in tag book line 2

How do I change this:

<?xml version="1.0"?>
<!-- initially, the default namespace is "books" -->
<book xmlns="urn:loc.gov:books" xmlns:isbn="urn:ISBN:0-395-36341-6">
  <title>Cheaper by the Dozen</title>
  <isbn:number>1568491379</isbn:number>
  <notes>
    <!-- make HTML the default namespace for some commentary -->
    <p xmlns="http://www.w3.org/1999/xhtml">
          This is a <i>funny</i> book!
      </p>
  </notes>
</book>

to this:

<?xml version="1.0"?>
    <book xmlns="urn:loc.gov:books">
    <book xmlns:isbn="urn:ISBN:0-395-36341-6">
      <title>Cheaper by the Dozen</title>
      <isbn:number>1568491379</isbn:number>
      <notes>
           <p>
              This is a <i>funny</i> book!
          </p>
      </notes>
    </book>

(above is from scoping@w3)

I'd like to make the scope for both namespaces to be all of books, if that makes sense.

thanks,

Thufir

You want:

<book 
    xmlns="urn:loc.gov:books" 
    xmlns:isbn="urn:ISBN:0-395-36341-6">

keeping the attributes within the single <book> node. Note that you can't have two root nodes, so two <book> nodes is not going to be acceptable in the above example.

The second example is not well-formed XML (one of the <book> tags is not closed), that's why the error occurs.

What you might want is:

<?xml version="1.0"?>
<!-- initially, the default namespace is "books" -->
<book xmlns="urn:loc.gov:books" 
      xmlns:isbn="urn:ISBN:0-395-36341-6">
  <title>Cheaper by the Dozen</title>
  <isbn:number>1568491379</isbn:number>
  <notes>
    <!-- make HTML the default namespace for some commentary -->
    <p xmlns="http://www.w3.org/1999/xhtml">
          This is a <i>funny</i> book!
      </p>
  </notes>
</book>
