In memory tree or strings ? Which is faster ?

[Erik Dasque]

All,   Here we are creating XML documents within what you'd call portal component and have a main object retrieve the XML code and process it through Xalan to get HTML.   Our component deliver in-memory DOM trees pass that to the Xalan processor the XSLT document [a file somewhere] has already been parsed, its DOM tree cached and passed to Xalan     [all this instead of strings,byte arrays, string buffers or InputStreams which would have to go through a non validating parser (correct ?)]   I made the following assumption : this is faster than giving Xalan 2 strings containing XML and XSLT ?   Am I correct ?   Ed.
