Subject Re: [digester]How to use SimpleRegexMatcher?
Date Wed, 30 Mar 2011 14:01:18 GMT
Hi Kurt,
I suggest you first creating a digester rule that helps you handling a
generic ParaItem element:

public final class ParaItemRule extends org.apache.commons.digester.Rule {

    @Override
    public void body(String namespace, String name, String text)
throws Exception {
        digester.push(new ParaItem(name, text));
    }

}

then plug the digester rules in the following way:

        Digester digester = new Digester();

        /* take a look at
http://commons.apache.org/digester/apidocs/org/apache/commons/digester/SimpleRegexMatcher.html
*/
        digester.setRules(new RegexRules(new SimpleRegexMatcher()));

        digester.addRule("Class/Parameter/Main/*", new ParaItemRule());
        digester.addSetNext("Class/Parameter/Main/*", "addMainParaItem");

        digester.addRule("Class/Parameter/SubText/*", new ParaItemRule());
        digester.addSetNext("Class/Parameter/SubText/*", "addSubParaItem");

THT, let me know! ;)
Simo

>   The elements under <Main> and <SubText> are all variable someday, both
name and amounts. So I define a ParaItem pojo to wrap sub elements of the two element.  That
means I want to create a Paraitem for every sub element ,whatever its name is, then add the
object to paraent object Parameter's list property saving all the related Paraitem.

tell me how to set a regex expression for a pattern. No way out, who knows the solotion ,
