Silly RedHat. Imagine using HTTP to transfer files... > - From memory, the c expat library news up an 8192 char buffer to unpack > *every* tag contents.

Expat does have a buffer that provides some "context" for the current event being reported, and the size of that buffer is defined by a compile-time definition. It should not be made too large, certainly. But it's not the way to retrieve normal document data from the parser, either. It's really only intended to do things like allow an application to retrieve character references when character data is reported, or to see what a tag actually looks like (we use this for page templates to help make minimal changes when we don't actually need to process TAL/METAL/I18N attributes on an element). Retrieving document text should always be done using the character data handler and a buffer to ensure the entire data within an element is collected, since multiple callbacks will be made quite often. -Fred -- Fred L.
