Non text data

[Solomon Habtom]

Hi
I am excited about the advancement and use of XML technology
in short period of time.It looks computers are going one step
up from networking.I got some Qs though.
1- How is multimedia represented in XML document.
Is it different from the way HTML refers external files?Like <Image > and other tags ?
2 - Does XML support mathematical calculations ? Is it possible to process numbers from different XML documents?
Thank you for your assistance!
Solomon

Multimedia - the easiest thing is to have a pointer to the media file, just like the <img> tag in HTML. If you want to carry binary data in the file, it has to be encoded with something like base64.
XML just represents data, it does not act on data. XSLT can act on data, including mathematical operations. There is a mathML that can represent complex equations, but it does not calculate anything.
