Subject: Re: Parsing unlimited xml element nesting with Digester
Hi Gary,
The standard rules engine in Digester should support "*/menu" fine
(though it will not support "foo/*/menu" type patterns). The pattern
"*/menu" will match any menu tag, regardless of what its parentage is.
If this isn't good enough (ie you want to avoid matching menu tags which
are children of an XYZ tag) then you can probably use the
ExtendedBaseRules or RegexRules rules engines (see also doc for method
Digester#setRules).
Hope this helps,
Simon
