Hi Rashid,

Below is ur digester rules def...


<digester-rules>
    <pattern value="eSummaryResult/DocSum">
        <object-create-rule classname="digesterexample.DocumentSummary" />
        <bean-property-setter-rule pattern="Id" propertyname="id"/>

        <pattern value="Item">
            <object-create-rule classname="digesterexample.Item"/>
            <set-properties-rule>
                <alias attr-name="Name" prop-name="name" />
                <alias attr-name="Type" prop-name="type" />
            </set-properties-rule>
            <call-method-rule methodname="setValue" paramcount="0"/>
            <set-next-rule methodname="addItem"/>
        </pattern>
    </pattern>
</digester-rules>

Below is your DocumentSummary class....

public class DocumentSummary implements Serializable {

    private static final long serialVersionUID = 3147951652544001256L ;

    private long id = 0 ;

    private List listitems = null ;

    public DocumentSummary() {
        listitems = new ArrayList() ;
    }

    public long getId() {
        return id ;
    }

    public void setId( long id ) {
        this.id = id ;
    }

    public List getListitems() {
        return listitems ;
    }

    public void setListitems( List listitems ) {
        this.listitems = listitems ;
    }

    public void addItem( Item item ) {
        this.listitems.add( item ) ;
    }

    public String toString() {
        final String COMMA = ", " ;

        final StringBuffer buffy = new StringBuffer() ;

        buffy.append( "DocumentSummary ( " ).append( super.toString()
).append(
                COMMA ).append( "id = " ).append( this.id ).append( COMMA )
                .append( "listitems = " ).append( this.listitems ).append(
                        COMMA ).append( " )" ) ;

        return buffy.toString() ;
    }
}

Below is Item class

public class Item implements Serializable {

    private static final long serialVersionUID = -8318635625838928564L ;

    private String name ;

    private String type ;

    private String value ;

    public String getName() {
        return name ;
    }

    public void setName( String name ) {
        this.name = name ;
    }

    public String getType() {
        return type ;
    }

    public void setType( String type ) {
        this.type = type ;
    }

    public String getValue() {
        return value ;
    }

    public void setValue( String value ) {
        this.value = value ;
    }

    public String toString() {
        final String COMMA = ", " ;

        final StringBuffer buffy = new StringBuffer() ;

        buffy.append( "Item ( " ).append( super.toString() ).append( COMMA )
                .append( "name = " ).append( this.name ).append( COMMA )
                .append( "type = " ).append( this.type ).append( COMMA )
                .append( "value = " ).append( this.value ).append( COMMA )
                .append( " )" ) ;

        return buffy.toString() ;
    }

}


Your Digester's parse method will return you an instance of DocumentSummary
instance with all item detail populated as expected....

Hope this works for you...
