ESQL <get-xml/> doesn't support namespaces

           Summary: ESQL <get-xml/> doesn't support namespaces
           Product: Cocoon 2
           Version: 2.0.2
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: core
        AssignedTo: cocoon-dev@xml.apache.org
        ReportedBy: sterling@hanenkamp.com


If the <get-xml/> ESQL tag is used inside of a namespace context, The root and
child nodes do not have a namespace associated with them. ESQL should allow the
inheritance of current xmlns declarations and apply those declarations to the
XML content read from the database. Perhaps a special syntax can be used to
specify the namespace definitions for elements within the database entry as well.

This document will reproduce the problem:

<?xml version="1.0"?>

<xsp:page xmlns:xsp="http://apache.org/xsp"
          xmlns:esql="http://apache.org/cocoon/SQL/v2"
          xmlns="http://sterling.hanenkamp.com/bugzilla"
          create-session="true">

<root>

<esql:connection>
  <esql:pool>somepool</esql:pool>
  <esql:execute-query>
    <esql:query>
      select *
      from sometable
    </esql:query>

    <esql:results>
      <esql:row-results>
        <row>
          <normal-element>This is in a namespace</normal-element>
          <esql:get-xml column="somecolumn" root="bad-element"/>
        </row>
      </esql:row-results>
    </esql:results>
  </esql:execute-query>
</esql:connection>

</root>

</xsp:page>

A hack I have created to work around the problem is to modify
org/apache/cocoon/components/language/markup/xsp/java/esql.xsl:


992a993,997
>               <xsl:if test="@ns">
>                       <xsl:text> xmlns=\"</xsl:text>
>                       <xsl:value-of select="@ns"/>
>                       <xsl:text>\"</xsl:text>
>               </xsl:if>

This allows me to specify a namespace for the root node which suffices for my
purposes. A more comprehensive solution is probably necessary.

A better solution would probably involve treating the database entry as an XML
fragment instead of a complete self-contained document.
