Mediawiki is strange thing - why in the world they are using different
type of outputs for parser functions and for parser tags?
Unfortunately, these things are preserved for better compatibility,
and won't be fixed.
Though I don't know why can't MW crew introduce a feature to parser's
setHook method:
instead of
function setHook( $tag, $callback )
function setHook( $tag, $callback, $expandTemplates = false )
so, the extension like SMW can register with something like:
$wgParser->setHook( "ask", cbfn, true )
no incompatibility will be introduced in such case (because third
parameter is optional).
About conversion of HTML-query output into the wiki text, is it really
necessary? I've thought that ask results are lists of the pagenames
(Titles) and values of propeties? Then, these are unlikely have to
contain HTML tags or wiki-tags, they should be plain UTF8 texts with
no special purpose characters, am I wrong?
Or, that's because of fansy HTML tables formatting ("table" attribute
of ask query)? Then, maybe it's better to limit functionality of
{{#ask|...}} to plain lists and template output? Or, just a one base
output class and extend with two different methods - one for <ask>,
another for {{#ask}}..
