The missing root element is another problem. I think SAX parsers that I have used require the document to be well-formed, whether it's valid or not. I think a missing root element means the document is not well-formed, however, I cannot confirm that with any references right off hand. If it's true, however, surely you can figure out a way to wrap your document stream, and add in the mock root element tags, right? Also you might want to look at XMLPullParser, which is what some XMPP (Jabber) packet libraries use (another low-memory alternative to DOM). However, even the XMPP packets I can think of are all technically well-formed . . . I don't know of a parser implementation right off that lets you turn off the well-formed constraint, but there sure oughta be one . . . As someone else mentioned, perhaps Jakarta Digester can deal with this?

I would like to be able to parse it without loading it entirely in memory (buffer) or without make a copy of this file to add the root tags... -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: August 24, 2005 4:09 PM To: Struts Users Mailing List Subject: [OT] Re: xmlparser simple question Gilbert, SAX works on an event based model. Memory is not an issue unless *you* are caching information as you receive events in your parser handler. The parser starts reading the stream. Each time it encounters the beginning of an element or an attribute, or the value of an element or attribute, or the end of an element or attribute, it simply fires an event. Your parser handler receives the event. At that point, the parser forgets that part of the stream and moves on to the next part. At any one time, the most it's going to cache is a single element or attribute name or value. I'm not sure though what you mean by "add the root in the parsing processing". Perhaps you could explain further.

The file have n o XML root, so I have to find how to add it in the parsing processing. Assuming that the file can be pretty big, how I can do it without at any time having the entire file in memory ? --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
