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

docbook2gjots

DOCBOOK2GJOTS(1)					      General Commands Manual						  DOCBOOK2GJOTS(1)

NAME

       docbook2gjots - Convert a DOCBOOK file to gjots format (on stdout)

SYNOPSIS

       docbook2gjots [ DOCBOOK-file ]

DESCRIPTION

       docbook2gjots converts a DOCBOOK XML file into gjots format.

       docbook2gjots uses gawk(1) to perform the conversion.

       <preface>,  <chapter>,  <section>,  <sect1>,  <sect2>,  <sect3> and <sect4> tags are used to define NewEntry and NewFolder boundaries. They
       should definitely have <title> tags.

       This is a quick and dirty hack using gawk(1) and does no formal checking of XML or SGML syntax nor does it  validate  against  the  DOCBOOK
       DTD. Consequently, if the syntax of the file is broken the conversion will probably fail.

       It is intended that a round-trip can be made so that gjots(1) can be used as a tool at all stages of DOCBOOK production - mainly as an out-
       line processor to help the author organise and order the work.  A document may well start its life in gjots(1) as the initial thoughts  are
       marshalled.  As	the  document  forms  up,  it can be converted to DOCBOOK with the following command which automatically adds tags such as
       <?xml...>, <para> etc:

	      gjots2docbook -b file.gjots >file.xml
	      docbook2pdf file.xml

       Or, starting with an existing DOCBOOK file:

	      docbook2gjots file.xml >file.gjots

       In the latter case, the document will already have a lot of DOCBOOK tags so to convert back to docbook, add the -e and -p options:

	      gjots2docbook -b -p -e file.gjots >file.xml
	      docbook2pdf file.xml
