Ant project DTD
Hi all !
I'm wondering if there is an Ant DTD ?
It could be useful for those who use an XML editor that is DTD-aware, or
someone like me who uses Vim and some scripts to validate their XML
files - but I must say it's quite hard to validate without the DTD ;)
Cheers,

Hi.
I wrote some DTD. It is not perfect but it can be use.
In this DTD:
- all deprecated argumens (according to the Ant documentation) are not
supported.
- there are some problems with the "available", "javadoc" and
"property"
tasks: these tags need have some required attributes (for property,
some of the following attributes are needed: value OR resource OR
file).
I didn't find any way to model this in a DTD. One solution could be
to change to something like this:
<!ELEMENT property EMPTY>
<!ATTLIST property
name CDATA #REQUIRED
type (value, resource,file) #REQUIRED
data CDATA #REQUIRED>
But then some changes are needed in the sources and documentation.
Waiting for some feedback.

I know for certain that both Oracle's parser and Xerces have partial
support for XML Schema (they don't have all the functionality implemented).

You can't do it with attributes... You cannot use exclusion, or
conditionnals. The only way would be using XML schema or another DTD
which instances could be XSLed to Ant's format.
I know that DTDs are quite unexpressive - but that's why schemas are
coming..The problem, though, is that there is no parser supporting it
for the moment (maybe Xerces will soon).
So either be patient, or sacrify some constraints : but don't forget to
mention it into your DTD's documentation !
Cheers,
Seb.

Hi.
I'm trying to build an Ant DTD for the basic functionnalities,
I mean for all buildin tasks but with no care about custom
tasks. But I've got a little problem with the "property"
tag. As far as I understood the Ant doc, the attributes of this
tag are the following:
- name is required
- one of the following is required (value, resource, file)
Do you know how to model this "one of the following..." ?

Yes, but it is possible to extend a DTD. I have such a DTD on my page :

It's impossible to define a DTD for ant. The tag names themselves have a
meaning that can be changed at runtime either in the XML file or
programmatically. Sure, it'd probably be possible to create a DTD for some
static set of Ant, but with it's pluggable architecture, it won't be a
complete one.
