Reading large XML documents

Hi Ricardo,

it is possible to use an alternative XML parser like SAX. In a report script you can call Java.Packages. To load a XML file for example:

this.init2 = function() {
        try {
           var locale = Packages.com.idsscheer.utils.locale.ALocaleConverter.getLocale( Context.getSelectedLanguage() ).getLanguage();
           var filedata = Context.getFile("filename.xml", Constants.LOCATION_COMMON_FILES);           
                            
           var factory = new Packages.javax.xml.parsers.DocumentBuilderFactory.newInstance();
           factory.setValidating(true);                        
           var builder = factory.newDocumentBuilder();            
           propertiesfile = builder.parse( new java.io.ByteArrayInputStream( new java.lang.String( filedata ).getBytes("UTF-8") ) );                                   
        } catch(e) {           
            //do nothing       
        }
    }

Hi Jens,

First of all, thank you very much for your help.

Many years have passed since the last time I use SAX in a development, so some of my statements may not be as exact as I would like. Sorry for that...

The main issue I have to face with is the creation of the ContentHandler(DefaultHandler)-derived type, in order to implement the startElement(), endElement(), characters(),... methods which manage the XML document in a proper way, that is:

1) Read the XML structure (XML nodes or nodesets)

2) Create some ARIS structures (models, objects and connections) using the previously read data. At this point, the ARIS Javascript-based API should be used in order to do the expected work but... within a Java type? 

From my current point of view, that's something I am not able to understand about how to carry it out...

Any idea?

Thanks, in advance, for all your help.

Regards,

Ricardo

Hi Ricardo,

I have quiet the same pbm i want to parse the xml file of a database :

var xmlExportOptionsWrapper = xmlExport.createDefaultXMLExportRootOptions(sourceDb.RootGroup(), [1033]);

but the xmlExportResultWrapper2.getFileResult(); --> JAVA HEAP SPACE

I tried -Xmx in launcher.cfg...

I you have any suggestion... i'll take it...

and dli.cfg as well :

db.jvm.params=-Xmx2048m -Dderby.system.durability\=test -Dderby.storage.pageReservedSpace\=0
