Hi Patrick, I thought it was more intuitive, sounds we have to update de doc. Anyway, to reply to your questions:
1) just create the Digester instance, set the RegexRules and start binding your rules: Digester digester = new Digester(); digester.setRules( new RegexRules( new SimpleRegexMatcher() ) ); digester.addCallMethod( "collection/doc/categ/*", "myMethod", 0 ); 2) yes, as reported in the javadoc I pointed: "* matches any sequence of none, one or more characters" like in the bash syntax; if you want to apply kind of filters, bind the rules with restrictive patterns (prefixes/postfixes); ie. given the rule: digester.addCallMethod( "collection/doc/categ/patt*", "myMethod", 0 ); collection/doc/categ/patt -> matches collection/doc/categ/pattern -> matches collection/doc/categ/patteRn -> matches collection/doc/categ/pattern -> matches collection/doc/categ/paBtern -> does not match HTH, have a nice weekend, Simo http://people.apache.org/~simonetripodi/ http://www.99soft.org/ On Sat, May 14, 2011 at 8:58 PM, Patrick Diviacco <patrick.divia...@gmail.com> wrote: > Thanks, > > 1) Is there any tutorial explaining how to use it ? > > 2) In my case, if I have more than one child, is the pattern detected > multiple times ? > > help is very appreciated! > > > > > On 14 May 2011 01:36, Simone Tripodi <simonetrip...@apache.org> wrote: > >> Hi Patrick, >> follow the Konstantin's suggestion, that's the way to achieve it.
