Re: [eclipselink-users] @XmlCDATA omit CDATA when element is empty?

[James Carr <james.r.carr@xxxxxxxxx>]

I kind of found a solution for this, but unfolding scenarios made my
solution invalid. :(

For those who might be reading, I was able to use the following:
@XmlCDATA
@XmlNullPolicy(nullRepresentationForXml =
XmlMarshalNullRepresentation.EMPTY_NODE, emptyNodeRepresentsNull =
true)

By setting fields to null it gives me the empty tag that I wanted
(with no CDATA wrapper).

Unfortunately, it looks like the legacy XML is generated with these rules:

1 - value = value wrapped in CDATA Tag
2 - empty string = empty node
3 - null = no node.

So I'm back in the same boat. If anyone has any ideas on how I can get
around this problem, I'd be grateful.

Thanks,
James
