[castor-dev] Re: Having trouble with whiteSpace="preserve"

[David Blevins]

Digging into the code I see that the setWhiteSpace("preserve") call in 
the generated code does nothing as all the \r, \n, and \t characters are 
stripped some time before the StringValidator's validate method is called.

Looking at the code in UnmarshalHandler, it seems the only way 
whiteSpace will get preserved is if the instance document has 
xml:space=preserve as an attrubite for the element or one of the 
element's ancestors.

Is this really the desired behavior?

I see Keith's note on the normalize method in StringValidator:
     * NOTE: THIS METHOD SHOULD NOT BE HERE..SHOULD BE MOVED
     * TO A FieldHandler or to the Unmarshaller...but not
     * here!!! (kvisco 20030125)
I'm guessing this is all related.

Hello Castor crew, hope all is well.

I am also having trouble with preserving whitespace, figured I'd respond 
to this thread for archive purposes (love news.gmane.org).

I am in the process of upgrading OpenEJB to Castor 0.9.5.3 from 0.9.2. I 
updated schemas and regenerated our config objects with no problems, but 
now all element data is without line separators.  The generated code for 
getContent() looks good:

        desc = new XMLFieldDescriptorImpl(
            String.class, "_content", "PCDATA", NodeType.Text);
        [snip]
        StringValidator typeValidator = new StringValidator();
        typeValidator.setWhiteSpace("preserve");
        fieldValidator.setValidator(typeValidator);
Any ideas?

Turns out the 'preserve' stuff works on elements, but not on attributes.
Not sure if that's a bug or not...

Hi Bill,

I believe whiteSpace="preserve" is supposed to do what you want, but if
it's not working, then you probably want to open up a Bugzilla report
(http://bugzilla.exolab.org).
Thanks,

So Anyway, based on castor and xml schema documentation, I should be 
able to specify a simpleType with the whiteSpace="preserve" attribute,



and the effect should be that my carriage return/line feeds would be 
preserved.  But it doesn't work.  Does castor support this?  Does the 
Xerces parser support this?  Is there another method to acheive this?

    I'm trying to preserve crlfs in some string content.  I've
    heard hints and rumours about the whiteSpace facet, but I'm
    having no luck getting it to work.  I'm defining a new
    simpleType, specifying the whiteSpace="preserve" facet, and
    creating an attribute of that type.  But the
    marshal/unmarshall behavior always seems to perform
    "collapse" behavior on my string.
