Trying to pull a variable out of an xml file...
Hello. I'm new to *ix and am trying to pull a variable or two from an xml document. The document is in the format:

Code:
<name>7_3(A).mov</name>
      <description>Some description from a file</description>
      <updatename>7_3_A.mov</updatename>
      <updatepath>Dailies Released</updatepath>
      <playlist>Selects Day 5,Dailies Day 5</playlist>

What I need to do is take the value or values from inside the <playlist> tags and assign them to variables. So, for this example, I'd like to be able to set $playlist1 to "Selects Day 5" and $playlist2 to "Dailies Day 5." The values in that xml tag will always be comma separated and there can be any number of them. I used grep to find the playlist lines, but don't know what to do next.

There are many more lines for each item described in the xml and there will be other instances of the <playlist> tag. I'll need to ignore instances of any value already set so, for example, once I've got the values "Selects Day 5" and "Dailies Day 5" from the above example I will need to ignore any further instances of those values until the script is executed again.

Any help would really be appreciated.

Thanks!

Dan

business::isbn::data

Business::ISBN::Data(3) 				User Contributed Perl Documentation				   Business::ISBN::Data(3)

NAME

       Business::ISBN::Data - data pack for Business::ISBN

SYNOPSIS

       see Business::ISBN

DESCRIPTION

       You don't need to load this module yourself in most cases. "Business::ISBN" will load it when it loads.

       These data are generated from the RangeMessage.xml file provided by the ISBN Agency. You can retrieve this yourself at
       <http://www.isbn-international.org/agency?rmxml=1>.  This file is included as part of the distribution and should be installed at
       ~lib/Business/ISBN/RangeMessage.xml.

       If you want to use a different RangeMessage.xml file, you can set the "ISBN_RANGE_MESSAGE" environment variable to the alternate location
       before you load "Business::ISBN". This way, you can use the latest (or even earlier) data without having to install something new or wait
       for an update to this module.

       If the default RangeMessage.xml or your alternate one is not available, the module falls back to data included in Data.pm. However, that
       data is likely to be older data.

       The data are in %Business::ISBN::country_data (although the "country" part is historical). If you want to see where the data are from,
       check $Business::ISBN::country_data{_source}.

SOURCE AVAILABILITY

       This module lives in the Github repository with Business::ISBN:

	       git://github.com/briandfoy/business--isbn.git

       If you have something to add, create a fork on Github and send a pull request.
