%D \module
%D [ file=x-corres,
%D version=2003.12.15, % replaces keep-02a cum suis
%D title=\CONTEXT\ XML Modules,
%D subtitle=Handling Correspondence Base,

%C
%C This module is part of the \CONTEXT\ macro||package and is
%C therefore copyrighted by \PRAGMA. See mreadme.pdf for
%C details.
%D The selection spec:
\setvariables
[contacts]
[selection=,
file=x-corres.xml] % fall back
%D First we define the group expansion pass:
\startsetups[contacts:collect]
\defineXMLprocess [contacts]
\defineXMLignore [contact]
\defineXMLargument [contactfile]
\processfile
\defineXMLenvironmentsave [contactgroup] [label=]
{\startXMLmappinggroup[contacts]}
{\XMLaddcontactgrouptoselection
\stopXMLmappinggroup}
\stopsetups
%D Next we define the main processing pass:
\startsetups[contacts:process]
\defineXMLprocess[contacts]
\defineXMLignore [contactgroup]
\defineXMLargument [contactfile]
\processfile
\defineXMLenvironmentsave[contact] [label=]
{\startXMLmappinggroup[contacts]}
{\XMLselectcontact
\stopXMLmappinggroup}
\stopsetups
\startXMLmapping[contacts]
\defineXMLsave [initials]
\defineXMLsave [formalname]
\defineXMLsave [informalname]
\defineXMLsave [title]
\defineXMLsave [prefix]
\defineXMLsave [suffix]
\defineXMLsave [telephone]
\defineXMLsave [mobiletelephone]
\defineXMLsave [telefax]
\defineXMLsave [email]
\defineXMLsave [address]
\defineXMLsave [information]
\defineXMLenvironment [p] \endgraf \endgraf
\defineXMLargument [member] \XMLaddcontacttoselection
\stopXMLmapping
%D The selection macros: we expand groups and replace them
%D by contact labels in the selection spec.
\def\XMLaddcontactgrouptoselection
{\edef\XMLcontactlist{\getvariable{contacts}{selection}}%
\edef\XMLgrouplabel {\XMLop{label}}%
\expanded{\doifinset{\XMLgrouplabel}{\XMLcontactlist}}
{\let\XMLgrouplist\empty
\XMLflush{contactgroup}%
\substituteincommalist\XMLgrouplabel\XMLgrouplist\XMLcontactlist
\expanded
{\globalsetvariables
[contacts]
[selection={\XMLcontactlist}]}}}
\def\XMLaddcontacttoselection#1%
{\addtocommalist{#1}\XMLgrouplist}
%D The main selector:
\def\XMLselectcontact
{\edef\XMLcontactlist {\getvariable{contacts}{selection}}%
\edef\XMLcontactlabel{\XMLop{label}}%
\doifelsenothing{\XMLcontactlist}
{\donetrue}
{\expanded{\doifinsetelse{\XMLcontactlabel}{\XMLcontactlist}}
{\donetrue}
{\donefalse}}%
\ifdone
\XMLflush{contact}%
\setups[contact:handle]%
\fi}
%D The default:
\startsetups[contact:handle]
\XMLflush{address}
\stopsetups
\setups[contacts:process]
%D Handy:
\def\XMLprocesscontacts
{\dosingleempty\XMLprocesscontacts}
\def\XMLprocesscontacts[#1]%
{\bgroup
\doifelsenothing{#1}
{\XMLprocesscontacts[\getvariable{contacts}{file}]}
{\setups[contacts:collect]%
\processcommacommand[#1]\processXMLfile
\setups[contacts:process]%
\processcommacommand[#1]\processXMLfile}%
\egroup}
\endinput
