[Tcllib-devel] XML generation

[Lars H. <Lar...@re...>]

Lately, a lot of the projects I've been working on have involved (i) 
generating Tcl data structures that could be viewed as a particular 
encoding of part of an XML document and (ii) converting said data 
structures to XML on output.

While (i) is always rather specific, the (ii) part tends to be very 
generic, and while it's code-wise very short, it kind of worries me 
that I'm copying the same procedures from project to project, so I've 
been thinking "maybe this should go into tcllib?" As a matter of fact, 
I've been somewhat surprised to not already find something along these 
lines in there, but maybe it's too elementary to make a package for... 
The intent is not to provide industrial capacity XML handling (there 
are well-known compiled extensions for that), but rather to provide a 
cheap package that you can put into your script when you just want to 
add XML as another output format.

The latest version of my command is TDLtoXML::xml_from_trees (but never 
mind the namespace) on http://wiki.tcl.tk/25681#pagetocbc2b8a8c. This 
coverts from a tdom list format to XML (cf. http://wiki.tcl.tk/26156), 
and that is perhaps something that should be scrutinised, since putting 
something like this in tcllib is an act of blessing its data format.

Comments, anyone?
