[Digester]what's the difference when parsing xml files like these?
i have the xml file as below:
<devices>
<device>
<name>Gw1</name>
</device>
<device>
<name>Gw2</name>
</device>
</devices>
then i can use digester to parse it with this class
it's aim it to put the <device> to a javabean and then
put all <deivce> to a arraylist.
List devices = new ArrayList();
public void parsedevice(){
Digester digester = new Digester();
digester.push(this);
digester.addCallMethod("devices/device", "addDevice",
1);
digester.addCallParam("devices/device/name", 0);
digester.parse(test.xml);
public void addDevice(String name, ){
Device device = new Device(name);
devices.add(device);
}
but after some consideration,i changed the xml file
like this:
<devices>
<device name='Gw1'/>
<device name='Gw2'/>
</devices>
then,the parse code doesn't work any more,anyone can
help me how to parse this kind of xml file?

Re: [collections] LinkedMap and ListOrderedMap
Posted by Stephen Colebourne <sc...@btopenworld.com>.
Both are provided to give you a choice of implementation.
IIRC, ListOrderedMap allows you to get a List object of keys, and also
allows you to choose your Map implementation (if you want something
unusual)..
To choose, the best answer is to performance test both in your application.
Bear in mind, the JDK implementation is like LinkedMap, so that might
suggest that is the better choice.

[collections] LinkedMap and ListOrderedMap
Posted by Koji Sekiguchi <ko...@bluemartini.com>.
These classes resemble each other, don't they?
Are there any explanation/condition for choosing one of them
whan I use ordered map in my application?

Koji

Hi Gao, as always i recommed you my reference reading:
http://www.onjava.com/lpt/a/2746
you must use addSetProperties method. Following changes would work!
//digester.addCallMethod("devices/device", "addDevice",1);
//digester.addCallParam("devices/device/name", 0);
digester.|addSetProperties|("devices/device/name", "device");
//public void addDevice(String name, ){
public void setDevice(String name) {
Device device = new Device(name);
devices.add(device);
}
||
Saludos.
