Most of the FCL are currently undocumented, feel free to send patches for documentation. I'm writing myself for some parts.

John,

it would be great if you could write something on that wiki page... Not aware of existing docs either...

Thanks,
Reinier

Done. See http://wiki.lazarus.freepascal.org/xmlconf.

In doing this, a few extensions come to mind:

1) Ability to set the string values used for boolean constants, as is possible in some other components.

2) A method Setkey(Paths:array of Widestring) which would clear the existing key stack and add each element of Paths as a separate stack element. (This is just a "convenience").

3) Ability to enumerate the siblings and children of a node. This ability exists in the TXMLDocument object used by XMLConfig, but as the object is declared "protected", it seems impossible to achieve this without modifying TXMLConfig or creating a descendant.

At the moment, I am planing to do the above and some current-project-specific additions in a descendant class, but if the above is of general interest, I could either produce a patch to XMLConfig or a descendant class for the 'general' extensions.

cheers,
John Sunderland
