I just started doing timing tests on my XML and I discovered that on an ASUS Transformer (Original) that a 31 line XML file took 2 seconds to load and a 219 line xml file took around 2.8 seconds to load. Those times are quite large, it is obviously preferably if we could cut them by about a fifth. I suspect that the massive amounts of branching contribute to the delay somewhat but more investigation needs to be done. Niall probably also knows what the cause of the problems are. I will be looking into it soon. I my goal would be to get the entire process down to 0.5 seconds on an Android device for any file that has 1000 lines or less. Maybe the reflection code also causes quite a bit of a slowdown. We shall see. I wonder how much of the reflection calls get cached as the parsing goes along.

Hello, I am having performance issues in Android parsing a very large XML file. Profiling trying to find where the bottleneck is, if I undestood correctly, the application is 44% of the time in the function "KXmlParser.getLineNumber", called from PullReader$Start.<init>, but looking at its source code it seems to only read an instance variable an nothing more. Can someone shed a light on this? I don't know it posting images is allowed here, so I uplodaded to an image sharing site: http://imgur.com/C5ocm Thanks, Rangel |

Hi Everyone, I have a XML schema that I would like to serialize using Simple. The schema contains elements whose attributes are part of attribute groups. Several types contain references to multiple attribute groups. Is there an ideal way to serialize this reference in the class I'm creating? I would like to avoid having to specify each attribute every time the attribute group appears in the schema--this would get messy if an update to the schema changes the attributes in a given group. Thanks! |

Hi
I'm trying to serialize an enum that looks like this:
public enum Category {
....
NEWSPAPER(Type.SUBSCRIPTION) {
@Override
public String getPrintable() {
return "Newspaper Subscription Fee";
}
},
MAGAZINE(Type.SUBSCRIPTION) {
@Override
public String getPrintable() {
return "Magazine Subscription Fee";
}
},
MEMBERSHIP(Type.SUBSCRIPTION) {
@Override
public String getPrintable() {
return "Club Membership Fee";
}
},
....
}
But when serializing it throws this exception:
org.simpleframework.xml.transform.TransformException: Transform of class
com.epik.dto.expense.Category$48 not supported
at
org.simpleframework.xml.transform.Transformer.write(Transformer.java:122)

at com.epik.client.BillClient.<init>(BillClient.java:23)
at com.epik.client.BillClient.main(BillClient.java:74)
The top class of the exception (AbstractClient), and the line that
generates the exception is this:
Serializer s = new Persister(new EpikMatcher());
StringWriter writer = new StringWriter();
s.write(resource, writer); //Exception generated Here
The matcher looks like this:
public class EpikMatcher implements Matcher {
@SuppressWarnings("rawtypes")
@Override
public Transform match(Class clazz) throws Exception {
if (clazz.equals(DateTime.class)) {
return new DateTimeAdapter();
}
return null;
}
}
It serializes when the enum doesn't implement an abstract method (as does
mine), but as I implement an abstract method, it crashes.
Thanks for any help

Hello Carlos, I don't know if i understood completely, you need to serialize only certain attributes from Class2, is that right? if yes, you need the annotation to make the atribute transparent to simplexml: http://simple.sourceforge.net/download/stream/doc/tutorial/tutorial.php#default see the @Transient annotation, maybe it is what you need.

Hi all,
I'm new with simplexml and I would like to ask how I can do one thing.
I have a class with an array of classes
class CLASS1 {
<CLASS2> ArrayList array;
...
I want to serialize CLASS1, just use some elements of CLASS2, but
when serialize CLASS2, save all elements, since the function of the
array is simply to keep a basic structure of CLASS2.
I tried to do with the Converter, but I have problems with the array.
Any idea to do it?
PD:Sorry for my level oh english
Thank you very much

hello everyone, i'm using simplexml with android and it works quite well, but i have a small question: the service side uses JAXB to render the xml sent to me over rest rpc and JAXB takes my Date field and transforms it in something like this: <c> <data>2011-12-15T11:49:18.888-03:00</data> </c> further reading show that format is in reality the DateTime data type: http://www.w3schools.com/schema/schema_dtypes_date.asp so, is there any way to make my Persister understads and generates it? Thanks in advance. |

i'm trying to read and write an interface using a Converter that uses the
element name as the simple class name and an attribute "package" for the
package name, and then
it works fine when reading, but not when writing,...
at first i had no "type" in the annotation and was not working but thought
that by adding it would solve it... wrong me.
since the handler is the interface for other people to implement, i would
like to have this style working for class resolving (i know there is the
default "class" attribute, but i rather avoid repeating tags and
attributes), but so that the other people only have to declare annotations
and not have to write some kind of converter.
bellow is code... cheers,
rui
annotation...
@ElementList(name = "handler", type = Handler.class, required = false)
private ArrayList<Handler> handlers;
input xml... WORKS fine :)
<handler>
<Downloader package="abc.kis.handler"/>
<KISRemote package="abc.kis.simple"/>
</handler>
output xml... hoops...
<handler>
<handler class="abc.kis.handler.Downloader"/>
<handler class="abc.kis.simple.KISRemote"/>
</handler>
converter...
@Override
public Handler read(InputNode in) throws Exception {
return (Handler)Class.forName(
in.getAttribute("package").getValue().concat(".").concat(in.getName())).
newInstance();
}
@Override
public void write(OutputNode on, Handler h) throws Exception {
KeepItSimple.PERSISTER.write(h, on);
on.setName(h.getClass().getSimpleName());
on.setAttribute("package", h.getClass().getPackage().getName());
on.commit();
}
example extending class...
@Root
public class KISRemote implements Handler {
@Override
public boolean accepts(Quest quest) {
return quest.getPathInfo().startsWith(Server.class.getName(), 1);
}
@Override
public boolean handle(Quest quest, Sponse sponse) {
String path = quest.getPathInfo().substring(
1 + Server.class.getName().length() +1);
if ("stop".equals(path))
System.err.println("GET THE SERVER HERE AND THIS MESSAGE OUT");
else return false;
return true;
}
}

Hi Wondering would it be possible to suppress automatic xml element "typing" when serializing objects into XML (i.e. have xml elements without class attribute). I am using Scala traits which translates to anonymous classes likely overriding default behavior. Best, Juha |

I'm asking because another app parsing identical XML than my app does the parsing 3x faster. I believe it uses the XML pull parser directly and cuts corners with namespace processing (this particular XML is namespace heavy). |
