	Travelling Meetings

Happy New Year, Chicago Perlers!

This month, Joel Berger is giving an introduction to the Mojolicious web framework (http://mojolicio.us <http://mojolicio.us/>). The presentation itself is a Mojolicious webapp, hosted on Heroku: http://mojolicious-introduction.herokuapp.com <http://mojolicious-introduction.herokuapp.com/>. RSVP for the presentation on the Meetup: http://www.meetup.com/ChicagoPM/events/219629915/ <http://www.meetup.com/ChicagoPM/events/219629915/>

For 2015, we want to expand the reach of Chicago.PM, and make it easier to join us for events. To that end, we're looking for businesses in the Chicagoland area who would like to host meetings. See the thread on our Meetup discussion page for details: http://www.meetup.com/ChicagoPM/messages/boards/thread/48618307 <http://www.meetup.com/ChicagoPM/messages/boards/thread/48618307>

Here's to a productive and fun year!

Subject: [Chicago-talk] Navigating an XSD
Message-ID: <CANpdWGX7WMjhQgxT_7UHvNeJmDDnPZ48WD17HX-eEn8eH8Cq4w@mail.gmail.com>

Hi,

I have an XSD document like below.  I've been googling and cpan-ing, but
can't find what I need (i know there are lots of XML packages), and I don't
know how to parse it using regexs (reliably).  I just want to read in this
XSD and navigate it like a perl structure, and extract field values like:

Field:ABS.1
Item:1514
Type:XCN
Table:HL70010
LongName:Discharge Care Provider

Field:ABS.2
...


Can anyone recommend a module or a method?

Thanks
Jay

I am personal partial to Mojo::DOM though it does not have any actual XSD
handling, it does xml just fine. That said, I would read through Matt
Trout's recommendations here: http://shadow.cat/blog/matt-s-trout/mstpan-3/

Hi Jay.  I have found some success using XML::Twig and XML::Writer for reading
and writing respectively, for relatively simple, but large XML files.

With XML::Twig, you can give it handlers based on blocks, for instance,
you're interested in.  For example:

my $t = XML::Twig->new(
    twig_handlers => {
        'person' => \&section,
    },
);
$t->parsefile($xmlfile);

sub section {
    my ( $t, $section ) = @_;

    # interested in a few elements within this section
    do_something_with( $section->first_child_text('birthdate') );
    do_somethingelse_with( $section->first_child_text('ssn') );
    #
    # ...

    # do not need that element again
    $section->purge;

    return;
}

See if that might work for you.

John

For writing XML::Writer is sufficient, though I think some DOM libraries 
allow you to print DOM objects to files too.  As far as reader 
libraries, the big ones that I've used before were XML::Simple, 
XML::Twig, and XML::LibXML.  Avoid XML::Simple. XML::Twig is ok and 
XML::LibXML may take more time to get started with but when I last 
tested those two XML::LibXML is much faster.

I've not used the Mojo::DOM, but with the name Dom, it probably has 
similar issues with any DOM parser -- good at small data sets and very 
easy to code with, but slow and memory intensive with large datasets.  
If you are doing anything with a lot of data, you'll want to read an 
article on DOM vs SAX parsing, and you may want to look at 
XML::LibXML::Reader  ( I think ).  I think it's a module that allows you 
to event parse down to specific nodes and then build up DOM objects, 
which are easier to work with in code.  It's been several years since 
I've had to do anything like that though.  The most important thing with 
XML parsing is knowing when to use an event based parser vs a DOM parser.

There may be some schema support in XML::LibXML too, but it's been a 
while since I've had to do anything with big xml fortunately.

Hi, now I'm a bit lost (having a hard time understanding the docs).  how do
I navigate to the element I want? (usable code below)

(I'm happy to do it with XML::Twig too if its easy)


I want to iterate through the "attributeGroup"s, getting their names, then
pull out each value for "attribute name" and for "fixed".

Thanks
Jay
