Hello, Is anyone aware of a way to write an XML document, using XMLBeans, without materializing the entire document in memory? Perhaps using a companion API such as XStream or StAX?
Our application communicates with other apps via XML messages. We've written schemas to define the messages, and used XMLBeans to generate java classes for manipulation of that data on the way in and out. Now we've encountered a need to send very large messages, which is causing memory problems since we must first construct the entire XMLBeans document before calling save(). I'm aware that I can manipulate the XmlOptions so that I can write the elements out bit by bit, i.e. I can write code such as: write A open tag write B open tag write B simple element B1 write B simple element B2 write B close tag write A simple element A1 write A close tag I'll get: <A><B><B1><B2></B></A1></A> But...I'll have hard coded the knowledge of the order in which the elements appear in the schema. I don't want to do that, since that is the value provided by XmlBeans' save() method - it writes things appropriately according to the schema. I'm considering writing my own implementation of this, so that as I assemble the document, elements are written to disk 'on-the-fly' as appropriate, and pruned from memory when their close tag is written. However, before I trudge down that road, I'd like to know if I'm reinventing the wheel. Has anyone got any ideas?
