Parse tree like data like XML by Perl?

[Davy]

Hi all,

I used to embed data in program use something like "case" or
"if..else". But my friend advice me to separate program and data. So I
want to use a tree-like data file like XML.

The question is:
1. Is there any better or easier standardized tree-like data structure
than XML?
2. If XML is better, I am new to it, what shall I learn to use it by
Perl?

Please recommend some tool or reading material about the topic, thanks!

Best regards,
Davy

XML is pretty good. The best way to learn it is to do some reading and
then jump in the water by coding a little bit. Some good resources to
get you started:

The absolute prime resource:
http://perl-xml.sourceforge.net/faq/

For a complete beginner maybe this is easiest:
http://search.cpan.org/~grantm/XML-Simple-2.15/lib/XML/Simple.pm

The full deal is something like this:
http://search.cpan.org/~kmacleod/libxml-perl-0.08/
Lot's of other modules on CPAN, too!

Good Tutorial:
http://www.xml.com/pub/a/2001/02/14/perlsax.html
Check out other stuff at xml.com, too.

Just do a little bit of reading, and then start coding, which is the
best way to understand XML. There's somewhat of a learning curve,
depending on how much you know alrady about perl and/or XML, but it
should be worth it.

Hi Michael,

Thanks a lot! I have write a lot of Perl code for hardware simulation
environment, but know a little about XML(I just know <>).

I will try to understand the prime you mention.
