tclxml-users

[Tclxml-users] is there support for early stopping for the parser

[Tobias G. <g....@be...>]

Hi all,

i am using TclXML excessively in the ECOBAS project
(http://dino.wiz.uni-kassel.de/ecobas/new_db/download_sw.html)
and came across the following question:

is there already a command somewhere in ::xml or ::sgml to quit parsing
based on an event. I want to stop parsing once a specific element occurs
in my elementstartcommand (to save execution time with lenghty xml files
when only one or few values have to be extracted). I could implement
this myself if its not there but maybe someone already came across the
same problem ..

Your application can control the flow-of-control by returning
a return code other than TCL_OK.  Returning TCL_BREAK will
halt the parser without throwing an exception
(ie. 'return -code break').
