Prefix breaks in version 0.3.20

[Novtopro]

In version 0.3.19, the spec below works as expected

but in 0.3.20 and above, it does not

The prefix is gone.

FYI @ronaldtse @HassanAkbar

Can be reproduced in metanorma/niso-jats#19 by updating the gem version.

Thank you @Novtopro for the report. This was exactly why I was worried about the fix for #150 because inner elements were not tested.

@HassanAkbar @suleman-uzair can we fix this ASAP with additional specs as mentioned in #151 ?

[HassanAkbar]

@ronaldtse Sure, I'm on it.

@HassanAkbar ok I am a bit confused with namespace behavior.

This is the XML Namespaces specification.

The "fully namespaced name" of an element name or an attribute, which contains a "namespace name" and a "local name" is called the "expanded name".

Look at 6.2, the "larger example":

<?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>

If a "default namespace" is defined at a parent element, all unprefixed child elements are supposed to be of the same namespace.

• "title" is actually "urn:loc.gov:books:title".
• "notes" is "urn:loc.gov:books:notes".

If a "default namespace" is defined on an element inside a tree that has a "default namespace" already defined, only the closest "default namespace" is used.

• "p" is "http://www.w3.org/1999/xhtml:p"
• "i" is "http://www.w3.org/1999/xhtml:i"

In the next example:

<?xml version='1.0'?>
<Beers>
  <!-- the default namespace inside tables is that of HTML -->
  <table xmlns='http://www.w3.org/1999/xhtml'>
   <th><td>Name</td><td>Origin</td><td>Description</td></th>
   <tr> 
     <!-- no default namespace inside table cells -->
     <td><brandName xmlns="">Huntsman</brandName></td>
     <td><origin xmlns="">Bath, UK</origin></td>
     <td>
       <details xmlns=""><class>Bitter</class><hop>Fuggles</hop>
         <pro>Wonderful hop, light alcohol, good summer beer</pro>
         <con>Fragile; excessive variance pub to pub</con>
         </details>
        </td>
      </tr>
    </table>
  </Beers>

When a namespace is set to the empty string "", then the applicable default namespace is cleared (no namespace).

• "brandName", "origin", "details" have no namespace.

According to 6.3, "default namespace does not apply to attribute names":

<!-- http://www.w3.org is bound to n1 and is the default -->
<x xmlns:n1="http://www.w3.org" 
   xmlns="http://www.w3.org" >
  <good a="1"     b="2" />
  <good a="1"     n1:a="2" />
</x>

Therefore

• "a", "b" have no namespace.
• "n1:a" has namespace of "n1:http://www.w3.org"
• "x" tag, "good" tag have the namespace of "http://www.w3.org"

We should obviously use these examples as specs.

@Novtopro I believe this problem has been resolved in 0.3.24. Could you help check? Thanks!

[Novtopro]

The issue is still there
