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! ;)

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.
