Hello, I get a question. Sometimes when I use saxon to query a XML file, the result is so big that a 'java heap space' is encountered. If I can set the size of result and only the size of data will be queried, the error will be avoided and the query will be more efficient. So is there a setting or parameter I can set to solve my problem, or some other ways I can go?  Thank you.
PS: my English is not very well, I hope I didn't make a mistake. I'm trying.
