[digester] setting attributes & text content on the same object...
Has anyone found any ways to do the following in digester.
Imagine the folllowing class
public class Param {
public void setName(String name);
public void setValue(String name);
}
And I want to parse XML like this...
<param name="foo">bar</param>
And I want the text value of the <param> element to be associated with the
'value' property of the Param.
Then in Digester I'm doing this...
String path = "foo/param";
addObjectCreate( path, paramClassName, "className" );
addSetProperties( path );
addCallMethod( path, "setValue", 0 );
addSetNext( path, "addParam", paramClassName );
Which works but the value is never set. Is anyone aware of any way around
this problem? I'm guessing its a current digester limitation.
I know I can parse this fine...
<param name="foo" value="bar"/>
Which is a work around for now - I'm just wondering if there's a way of
using attributes and text content for the same object & element in digester.

Re: [digester] setting attributes & text content on the same object...

Actually it turned out to be a bug in my code to do with the order in which
the properties were set and when the addParam() method was called by the
addSetNext() rule. Sorry about that everyone!
So either of these approaches work fine.
String path = "foo/param";
addObjectCreate( path, paramClassName, "className" );
addSetProperties( path );
addBeanPropertySetter( "value" ) );
addSetNext( path, "addParam", paramClassName );
or
addObjectCreate( path, paramClassName, "className" );
addSetProperties( path );
addCallMethod( path, "setValue", 0 );
addSetNext( path, "addParam", paramClassName );
Its just that the "value" property may be set after the addParam() method is
called (the addSetNext() rule).

hi craig
you mean the BeanPropertySetterRule, don't you?

i think that you should be able to use the BeanPropertySetterRule to set a
specified property with the body text.

This is courtesy of the (relatively) new SetPropertyRule -- Jason van Zyl
ran into a need for this one, and suggested this approach. We could
probably extend SetPropertyRule to work they way you want by grabbing the
value from the body content if there is no "value" argument.
