Hi, I'm new with Java graphic. I have an xml file with the informations
about the slots (attribute) of each module of my sistem, like

<module name="NomeComponente" type="action">

<phase>1</phase>

<level>2</level>

<basic>

<caption>front-office telefonico</caption>

<description>modulo per la gestione degli appuntamenti di
primo livello: possibilit? di confermarli, modificarli o
rifiutarli. In caso di rifiuto l'operatore pu?
registrarne il motivo</description>

</basic>

<auto-execute>false</auto-execute>

<sequencing>

<previous_step>nomeComponentePrecedente</previous_step>

<next_step>nomeComponenteSuccessivo</next_step>

</sequencing>

<permissions>

<read>id_operatore1;id_operatore2;...;id_operatoreN</read>

<execute>id_operatore1;id_operatore2;...;id_operatoreN</execute>

</permissions>

< </module>

I have to buil a GUI from these informations with a panel that
shows them (for each attribute a lable and a text field I think, so the user
can read the attribute and modify it). I think I need an xml parser to store
the attributes of each module an present them. is there a ready parser
written in Java I can modify for my aim? Can someone help me?

Thanks in advance

Martino

Here's what I would do. Read in the XML using SAXParser, and your own
"handler". Something like:

MyHandler handler = hew MyHandler();
SAXParserFactory factory = SAXParserFactory.newInstance();
SAXParser parser = factory.newSAXParser();
parser.parse(<File>, handler);
...

class MyHandler extends DefaultHandler {
<see the JavaDoc for DefaultHandler to know how to parse
XML elements as they are read from file.>
<use this handler to fill in objects that contain the data
you will eventually use to populate your GUI>
}

------------------
Your GUI would call the above parsing routines to parse the XML file,
and then use the data acquired in "MyHandler" to build whatever
components
it needs.

Hope that helps.
