Here's the trick:
The attributes will be defined by someone else using the class,
so the attributes will not be static. Any attributes could be set
in the format class, and I need to copy them. I want this to be
generic as possible, so I can loop through a set of TD's, set a
condition to modify a format, then apply that format to only those
records that need it. I can't just call setBgColor on all the TD's,
unless I do some tricks with reflexion to pass the name of the method
call. I want this to be simple and easy for a user.
So, my question still remains:
How do I copy these attributes from one TD to another?
I've tried to create a ConcreteElement and do it like this:
TD data = new TD("Foo");
TD format = new TD();
format.setBgColor("#FFFFCC");
Enumeration formatEKeys = format.attributes();
ConcreteElement ce = new ConcreteElement();
while (formatEKeys.hasMoreElements()) {
String o = (String) formatEKeys.nextElement();
System.out.println (o);
String value = format.getAttribute(o);
System.out.println (value);
ce.addElementToRegistry (o, value);
System.out.println (ce);
data.addElement (ce);
}
System.out.println (data);
I get the following result:
bgcolor
#FFFFCC
<>#FFFFCC</>
<td>Foo<>#FFFFCC</></td>
Almost, but not quite. Can someone help me clean up this
code so it produces:
<td bgcolor="#FFFFCC">Foo</td>
Thanks yet again.
