Digester rules problem.
Hello,
<response query="10.70.0.2,v2p,3,1,0" result="true">
<attribute name="ip">10.70.0.2</attribute>
<attribute name="slot">3</attribute>
<attribute name="port">1</attribute>
<attribute name="status">active</attribute>
</record>
In the above XML, I have a bean as following:
public class Response {
private String query;
private boolean result;
private String ip;
private String slot;
private String port;
private String status;
....
}
For the query, result, I can easy to use the following codes to parse.
Digester digester = new Digester();
digester.setNamespaceAware( true );
digester.setXIncludeAware( true );
digester.addObjectCreate( "response", Response .class );
digester.addSetProperties( "response", "query", "query" );
digester.addSetProperties( "response", "result", "result" );
But, how can I set those <attribute/> into the related properties?
Please help.
Thanks.
Eric

Hi Eric,
I took a quick look at Digester, I have to say that I am not a
Digester guru (rather I am a newbie), but looking at source code I am
able to get what you are looking for using the code below.
public class ResponseTest {
@Test
public void buildTest() throws IOException, SAXException {
Digester digester = new Digester();
digester.addObjectCreate("response", Response.class);
digester.addSetProperties("response", "query", "query");
digester.addSetProperties("response", "result", "result");
BeanPropertySetterRule rule = new BeanPropertySetterRule();
rule.setPropertyNameFromAttribute("name");
digester.addRule("response/attribute", rule);
Response r =
digester.parse(this.getClass().getResourceAsStream("Response.xml"));
assertNotNull(r);
assertEquals("10.70.0.2", r.getIp());
assertEquals("1", r.getPort());
assertEquals("3", r.getSlot());
assertEquals("active", r.getStatus());
}
}

Digester is a good piece of software, I would love, but not at the
moment, I have so little free time and so many things to do.
Anyway, I have added it in my todo list.

Hi Mau,
thanks for providing to Eric the needed help, very appreciated! Just a
minor hint: the double SetProperties rule declaration can be replaced
by just one call:
public class ResponseTest {
@Test
public void buildTest() throws IOException, SAXException {
Digester digester = new Digester();
digester.addObjectCreate("response", Response.class);
digester.addSetProperties("response", new String[]{ "query",
"result" }, new String[]{ "query", "result" });
[OMISS]
}
}
since attribute names are exactly the properties names, the
attributes/properties arrays can be omitted:
public class ResponseTest {
@Test
public void buildTest() throws IOException, SAXException {
Digester digester = new Digester();
digester.addObjectCreate( "response", Response.class );
digester.addSetProperties( "response" );
[OMISS]
}
}
if you use the Digester3 rules binder (which I prefer, yuk yuk), you
can write the rules as
new AbstractRulesModule()
{
@Override
public void configure()
{
forPattern( "response" )
.createObject().ofType( Response.class )
.then()
.setProperties()
.addAlias( "query", "query" )
.addAlias( "result", "result" ),
forPattern( "response/attribute" )
.setBeanProperty().extractPropertyNameFromAttribute( "name" );
}
}
About your question: currently there's NO full XPath rule matcher
engine :( if you are interested on providing an implementation we can
discuss about it on the dev@ ML
HTH, have a nice day!!!

Hi Simo,
looking at the http://s.apache.org/OQ0 I realized that Digester uses
an xpath-like string, I am wondering if there is a way (or a rule)
which allows using full xpath syntax (Eric could have used something
like "response/attribute[@name='ip' ]").
Is there any Rule implementation about this specific topic?

Hi Eric,
I can provide you the solution but I'll be busy for the whole morning.
Please wait I'll send you the hints ASAP.
