Does the World Need Binary XML?

Maybe this is like comparing assembly to C

[Stevyn]

Programs written in assembly can run faster than programs written in C, but it's easier for someone to open a .c file and figure out what's going on.

I'm sure when C came out, the argument was similar that the performance hit doesn't make up for the readability or cross compatibility. But as computers and network connections became faster, C becomes a more viable alternative.

Amen To That

XML, as originally designed, is deliciously straightforward. Data is encoded into discrete, easy-to-process chunks that any given XML parser can make sense of.

XML, as implemented today, is often little more than a thin wrapper for huge gobs of proprietary-format data. Thus, any given XML parser can identify the contents as "a huge gob of proprietary data", but can't do a damned thing with it.

Too many developers have "embraced" XML by simply dumping their data into a handful of CDATA blocks. Other programmers don't want to reveal their data structure, and abuse CDATA in the same way. Thus, a perfectly good data format has been bastardized by legions of lazy/overprotective coders.

The slew publications exist for the sole purpose of "clarifying" XML serves as testament to the abuse of XML.

Re:there are already standards for this...

I'll say it again.. Its not the size of the document its the overhead in parsing.

The article doesn't go far enough...

It doesn't tell us what the specific performance problems are with XML. Does it take too long to transmit? Does it take too long to validate? Does it take too long to parse? Does it take too long to format? What's the real problem here?

From experience, I can state that using XML in any high performance situation is easy to screw up. But once you get past the basic mistakes at that level, what other inherent problems are there?

Oh, and just stating "well, the format is obviously wasteful" just because it's human readable (one of its primary, most useful, features) is NOT an answer.

I get the feeling that this perception of XML is being perpetuated by vendors who do not really want to open up their data formats. Allowing them to successfully propagate this impression would be a very real step backwards for all IT professionals.
