Hi Is a DOM always instantiated for transformation, regardless of whether the factory is a SAXTransformerFactory or not?
I have XML files 100-200MB in size and I wish to transform and insert their records into a DB using a Xalan extension to perform the INSERT. I get OutOfMemoryError, no surprise. I init the transformation with SAXTransformerFactory and therefore use TransformerHandler, XMLReader and write to a StreamResult. Intuitively I envision a mode where the transformation is streaming, 'on the fly' with the transformation output streaming out before the entire input document has been parsed. On the other hand, my sense of reality says, a stylesheet can not be correctly applied until the entire document is instantiated as DOM. Sorry if this has been discussed before - any pointers for performing really large transformations? Thanks, chris
