[digester]How to use SimpleRegexMatcher?

Hi all:

I want to match some unknow elements nested some parent element where some newly defined element might be added sometime.

The sample xml is as below:

<Class name="jp.hangame.motecoorde.coordinate.bo.CoordinateCommentBoImpl" method="entry"> 
            <Parameter name="comment" index="0" type="insert" table="MOCO_CODICMT">
                <Main>
                    <DeviceType constant="true">pc</DeviceType>
                    <CheckStatus constant="true">N</CheckStatus>
                    <ValidCheck constant="true">Yes</ValidCheck>
                    <CheckDesc></CheckDesc>
                    <UserId>userid</UserId>
                    <PrimaryKey1>cmtno</PrimaryKey1>
                </Main>
                <SubText>
                    <!--<Type constant="true/false"></Type>-->
                    <!--<Title>title</Title>-->
                    <Content>contents</Content>
                    <WriterId>writeid</WriterId>
                    <WriterUserName>userid</WriterUserName>
                </SubText>
            </Parameter>
</Class>


   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.

   The Paraitem source code is following:

public class ParaItem {
    private String elemName;
    private String argPropNameOrValue;
    private boolean isConstant;
    public ParaItem() {
    }
    public ParaItem(String elemName, String argPropNameOrValue,  boolean constant) {
        this.elemName = elemName;
        this.argPropNameOrValue = argPropNameOrValue;
        isConstant = constant;
    }
    public ParaItem(String elemName, String argPropNameOrValue) {
        this.elemName = elemName;
        this.argPropNameOrValue = argPropNameOrValue;
    }
    public String getElemName() {
        return elemName;
    }
    public String getArgPropNameOrValue() {
        return argPropNameOrValue;
    }
    public boolean isConstant() {
        return isConstant;
    }
}



 The Parameter source code is below:
public class Parameter {
    private String index;
    private String operType;
    private String dataType;
    private List<ParaItem> listMainFiled =new ArrayList<ParaItem>();
    private List<ParaItem> listSubField =new ArrayList<ParaItem>();
    public Parameter(String operType) {
        this.operType = operType;
    }
    public List<ParaItem> getListMainFiled() {
        return listMainFiled;
    }
    public void setListMainFiled(List<ParaItem> listMainFiled) {
        this.listMainFiled = listMainFiled;
    }
    public List<ParaItem> getListSubField() {
        return listSubField;
    }
    public void setListSubField(List<ParaItem> listSubField) {
        this.listSubField = listSubField;
    }
    public String getIndex() {
        return index;
    }
    public void setIndex(String index) {
        this.index = index;
    }
    public String getOperType() {
        return operType;
    }
    public void setOperType(String operType) {
        this.operType = operType;
    }
    public String getDataType() {
        return dataType;
    }
    public void setDataType(String dataType) {
        this.dataType = dataType;
    }
    public void addMainParaItem(ParaItem pi){
       getListMainFiled().add(pi);
    }
    public void addSubParaItem(ParaItem pi){
        getListSubField().add(pi);
    }
}

   I suppose regex rule is the best way to make it , but googling and the javadoc doesn't tell me how to set a regex expression for a pattern. No way out, who knows the solotion , thanks.
