What I said in my last mail is valid for the input stream as well. Parsing is about trying to match some content in multiple ways. This implies that you need to check if something matches and if it fails try matching something else. That also means you need to backtrack or better you need to get back and forth within a stream. This makes streaming less an option because you’ll always need to buffer and the buffer is likely to be as big as the whole content. I don’t know what you are trying to achieve but probably there is another solution. Your mail sounds as you are concerned about memory consumption. Assuming further it is probably not a single entity you try to parse but a list of the same entity. In the case you could leave out the outermost star or plus parser and use the parser for a single entity until the end of the stream. So you would use the parser multiple times producing smaller chunks in memory. Hope this helps, Norbert
