[betwixt] How to get mixed-content of element?
And how to write element wich have mixed content e.g.
<sql id="1">
<![CDATA[
SELECT * FROM userprofile WHERE userprofile.id < 10
]]>
</sql>
Hi,
I've searched the mailing list for this one and maybe I'm missing something
very obvious, but - is it possible to get the text of mixed element content
with betwixt?
e.g.
<foo>
<bar>blah</bar>
This is text...
</foo>
In this case I'll have a class for Foo and bar will be mapped to a String
property of Foo. But what happens to the text?
Off topic - I am very happy with Betwixt so far (just started playing with it)
and I have high hopes that it will eliminate the need for maintaining my own
tool (based on the SAXModelBuilder example from my book).
Thanks,

a good question :)
it's undocumented but used in element rule. james created it before i
started being involved with betwixt. i have an idea that it's used to help
with the property type but i'm not 100% sure. i intend to investigate it
soon so that i can create some test cases for it. if you find out - please
let me know!

body text should be escaped before it's written. if it's not then thats a
bug. (i will take a look at this and see if we have a test case for it.)
there are some (uncommon?) use cases which may require the use of <![CDATA[
..]]> but this support needs to be rolled out for all body text rather
than just this particular kind.

thanks. everything works very good. But I have some questions concerning the
code you've done
1)What for do you use the attribute "type" ?
2)I think that the body should be wrapped by <![CDATA[ ... ]]> Otherwise we
will get invalid xml file if the bean property has string value like "P&G
company"

hi
i've added this functionality (it took a bit more work than i'd thought
but it's worth it). if you check out CVS HEAD and build the latest version
or wait until a new nightly build then you give it a go. note that the
element name (in the betwixt file) is text. there should be some
documentation about this feature on the web site. (but i'll take another
look and maybe improve it tommorrow.)
if you try it, please let me know how you get on.

yes it's very logically.
So all xml entities (elements,attributes,element body) can be deternined in
the betwixt files

again, i'm afraid that there's no way to do this at the moment.
i don't really see how it could be automatically supported by
introspection - but it would be reasonable to add a new element type to
the .betwixt xml. we'd have something like <content property='foo'/> which
would convert whatever property foo returns to a string and then add it to
the xml in the given position.
how would this sound?
