XML: People

Continuing with the theme…

There is the bitterly smart Fredrik Lundh and his excellent ElementTree (which will be in Python 2.5) “it makes XML documents look like a bunch of nested lists”. I find the iterparse function interesting. (Of course someone as made a similar python interface but with all libxml2’s functionality and compliance).

Another figure is the fatherly Uche Ogbuji who is heavily involved with the 4suite™ “platform for XML and RDF processing” which is built on by the Amara XML toolkit. Very pythonic yet very concerned about the XML-Specs it would seem.

I should mention the bearded Tim Bray. He gives me hope, but not only that – he contributed to the XML standard (and the excellent Atom standard) and has ‘recently’ written a nice C library for generating XML called Genx. It seems Genx is pretty much feature complete, which is cool (because that means handling UTF-8 and namespaces ‘well’).

XML: Digestion

Well, so I said:

a custom XML parser (that maps onto application specific data structures) would be cool.

– it seems the Jakarta Commons project has a Digester Component which does this programmatically. One of the Scribus developers made something similar for C++

David Mertz’s XML Programming Paradigms

Also by the same author, The Xom Java Xml Api (which he calls a “A rigorously correct tree-oriented XML model”).

TagSoup, a SAX-compliant parser, for all that ‘wild’ HTML written in Java. Similarly BeautifulSoup written in Python.

From CUJ: Generating a custom XML parser (that maps onto application specific data structures) would be cool.

XML Apis

(For future reference)

StAX

(Ok, so StAX is the reverse of SAX which makes it more like the normal parser/tokeniser behaviour, but SQLite goes the other way (like SAX) because the author is convinced it is better, and I’ve yet to experience any of these situations.)

Hilarious

// Preconditions: variable i in memory
// Post conditions: variable i incremented by one
// Method:
//1: fetch i from memory into register
//2: increase register value by 1
//3: write value of register into memory
i++;

From Fred Emmott.

Updated: This is interesting for two other reason, now I have the prefix operator (++i;) fixed in my head, and there is actually a need for such documentation: Interlocked.Increment Method (.NET’s System.Threading namespace).
