Re: [xml-dev] I processed a 3GB XML file ... using XSLT streaming

[Peter Hunsberger <peter.hunsberger@gmail.com>]

It might be worth noting that streaming XML has been around for some many years now (in spite of the W3C's belief in what makes a well formed document).  I think the first custom XML parser I ever wrote was for the Sports TIcker data feed probably not long after they first started up 15 years ago...   The thing that has changed, and I think maybe the point of Roger's original post (whether he intended it or not), is the ability to use XSLT to handle the streaming data without having to resort to custom software.

Absolutely true.

Also, there could be cases when the XML data is generated in real time
continuously and non-stop,  and must be processed again in real time.
In such scenarios even terabytes of RAM wouldn't help.
