How to map the following xml uisng digester
Hi: gurus I have the following xml file that I like to map to Java objects
but don't know the right approach after just reading the Digester document
<eSummaryResult>
<DocSum>
<Id>27731</Id>
<Item Name="Title" Type="String">The American journal of
obstetrics and diseases of women and children</Item>
<Item Name="MedAbbr" Type="String">Am J Obstet Dis Women
Child</Item>
<Item Name="IsoAbbr" Type="String"></Item>
<Item Name="NlmId" Type="String">14820330R</Item>
<Item Name="pISSN" Type="String">0894-5543</Item>
<Item Name="eISSN" Type="String"></Item>
<Item Name="PublicationStartYear" Type="String">1868</Item>
<Item Name="PublicationEndYear" Type="String">1919</Item>
<Item Name="Publisher" Type="String">W.A. Townsend &
Adams,</Item>
<Item Name="Language" Type="String">eng</Item>
<Item Name="Country" Type="String">United States</Item>
<Item Name="BroadHeading" Type="List"></Item>
<Item Name="ContinuationNotes" Type="String"></Item>
</DocSum>
</eSummaryResult>
My objects are
public class DocumentSummary implements Serializable {
private long id = 0;
private List<Item> listItems = null;
// Omitted Setter and getters for Brevity
}
public class Item implements Serializable{
private String name;
private String type;
private String value;
// Omitted Setter and getters for Brevity
}
Here is my rules file, but I got stuck after parsing the "Id" tag and don't
know how to proceed further, any help would be appreciated.
<digester-rules>
<pattern value="eSummaryResult/DocSum">
<object-create-rule classname="digesterexample.DocumentSummary"/>
<set-next-rule methodname="add"
paramtype="digesterexample.DocumentSummary"/>
<set-properties-rule/>
<bean-property-setter-rule pattern="Id" propertyname="id"/>
<set-properties-rule/>
</pattern>
Thanks,
RJ

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...
