The ant-contrib project is providing conditional tasks which may help,
but
if you want to have your own syntax and the very specific url
availability
as a condition (like you wrote), maybe using a script (using scriptdef
for

i would go via <script(def) .../> and a scripting language running in
BSF
(JRuby, Groovy, Beanshell ... )
or use the AntBuilder@(protected)
