[jira] Commented: (COCOON-2191) XML namespace declaration added in certain circumstances

["Andreas Hartmann (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/COCOON-2191?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12584774#action_12584774 ] 

Andreas Hartmann commented on COCOON-2191:
------------------------------------------

As a workaround it is sufficient to add an identity XSLT transformation after the i18n transformation. I guess this rids the SAX stream of the prefix mappings.

>                 URL: https://issues.apache.org/jira/browse/COCOON-2191
>             Project: Cocoon
>          Issue Type: Bug
>          Components: Blocks: Serializers
>    Affects Versions: 2.1.12-dev (Current SVN)
>            Reporter: Andreas Hartmann
>
> Pipeline:
>     <map:generate src="test.xml"/>
>     <map:transform type="i18n"/>
>     <map:serialize type="xml"/>
> Source document (test.xml):
>     <?xml version="1.0" encoding="UTF-8"?>
>     <document>
>       <i18n:text xmlns:i18n="http://apache.org/cocoon/i18n/2.1">foo</i18n:text>
>       <element/>
>     </document>
> Output of XMLSerializer:
>     <?xml version="1.0" encoding="UTF-8"?>
>     <document>
>        foo
>       <element xmlns:xml="http://www.w3.org/XML/1998/namespace"/>
>     </document>
> The xmlns:xml declaration is added due to an underflow of the Namespaces stack. The field Namespaces.last becomes 1 and therefore the xml namespace is committed (which I guess should never happen). I'm not sure yet if this is a problem of the serializers block or maybe of the I18nTransformer.
> The problem is that this happens when generating RSS feeds, and IE doesn't accept them if they contain namespace declarations.
