Subject [jira] Commented: (JCR-674) String properties with invalid XML characters export as invalid XML
Date Thu, 21 Dec 2006 13:32:22 GMT
    [ http://issues.apache.org/jira/browse/JCR-674?page=comments#action_12460262 ] 
Jan Kuzniak commented on JCR-674:

One more thought: maybe we should split this issue into 2:
- leave values encoding (to base64) here,
- create new issue for names encoding in Session.exportSystemView.

What do you think about it?

>                 Key: JCR-674
>                 URL: http://issues.apache.org/jira/browse/JCR-674
>             Project: Jackrabbit
>          Issue Type: Bug
>          Components: xml
>    Affects Versions: 1.1.1
>            Reporter: Joshua Levy
> As noted in the current JCR 1.0.1 maintenance draft, sections 6.4.1,
>, XML export of string properties that contain invalid XML
> characters isn't well-defined currently, since those characters are
> not permissible in XML.  The proposed fix is to use base64
> encoding for such values in System View.
> Most characters below #x20 are examples of this.  Currently, these
> are escaped numerically in output (such as (amp)#0; )  but
> such escape sequences can't be parsed by the XML
> import methods.
> The current behavior is particularly problematic, because the user
> doesn't know the output is corrupt until later, when they try to import it
> and get InvalidSerializedDataException.
> If for some reason the base64 option is delayed, it might
> make sense, as an interim solution, to fail on export
> or to somehow patch import to relax its parsing and allow
> these escape codes.
