A quick and dirty approch with XML::Twig (forget xml::simple) and using xml data in Trace On's scratchpad must be a good starting point for your further investigations: each twig's handler is triggered when the specified XPATH is encountered: notice the ugly cur_league workaround.. #!/usr/bin/perl use strict; use warnings; use XML::Twig; my $cur_league='UNKNOWN'; my $t= XML::Twig->new( twig_handlers => { 'league/id' => sub{ $cur_league = $_[1]->te +xt}, 'event/startDateTime'=>sub{ print "$cur_lea +gue,",$_[1]->text,","; }, 'event/homeTeam/name'=>sub{ print $_[1]->te +xt }, 'event/awayTeam/name'=>sub{ print ",",$_[1] +->text,"\n"; } #add more handlers as needed.. } ); $t->parsefile('trace_on.xml'); __OUTPUT__ 1739,2015-06-24T11:59:00Z,Union Mar del Plata,C.

Thank you! That helped a lot. I spent quite some time to do some basic research on XML Twig and XML. But I still do not understand how your workaround works. It is cool that you get the league-number for every line. I would like to have something like that for all the 'spreads' as well. But that seems to involve some kind of recursion. And my little brain is to small for that. I have tried to understand this tutorial. But I am not all the way trough... pad://http://www.xml.com/lpt/a/750	[reply]

As side note XML::Twig has his own site with many tutorials and a helpfull QuickReference. In my homenode i also have this bounch of links about the topics: XML "If you need to deal with XML, first, we’re very sorry." b d foy http://www.effectiveperlprogramming.com/2011/07/rewrite-xml-with-xmltwig/ and http://www.effectiveperlprogramming.com/2010/03/process-xml-data-with-xmltwig/ and http://it-is-etc.blogspot.it/2012/07/perl-how-to-manipulate-xml-files-using.html and http://perlmeme.org/tutorials/parsing_xml.html speed comparison http://www.robinclarke.net/archives/xml-parsing-with-perl mirod schratchpad and Re: Another simple XML Twig question and http://www.xml.com/pub/a/2001/03/21/xmltwig.html ambrus's Do not reinvent the wheel: real-world example using XML::Twig and also http://perl-xml.sourceforge.net/faq/ and choroba about XML The trick about the league (that relies on the stability of the XML feeded and that make the code somehow fragile) is very simple: The `$cur_league` begins with a dummy value. Then, when the file is parsed (from first line to the bottom) and when a league tag is encountered the relative twig_handler is triggered, setting `$cur_league` with a real value. Then are triggered handlers for events (date,team..): when the first date is found the handler prints the league, a comma, the date, another comma. The current league is so valid for all events included in the `<league> </league>`. Next occurence of 'league' will set `$cur_league` to a new value. And so on. i hope i was clear.. if no, let me know HtH L* There are no rules, there are no thumbs.. Reinvent the wheel, then learn The Wheel; may be one day you reinvent one of THE WHEELS.

If you add `warn $_->path, "\n";` to every callback you can observe a magical hint Then try something `'spreads/spread' => sub { ... }` ... http://xmltwig.org/tutorial/	[reply] [d/l] [select]
