Thanks for the replies. I need to extract the values of the message and
I was hoping to create objects from them and stuff the objects into an
arraylist so I can iterate through them. Eventually the idea is to
build a servlet that will format the messages in a easier to read
format, provide searching and message grouping by the dialogID. I have
played with perl and I feel the use of Java objects is easier for me to
understand than using perl's hashes. Obviously you feel perl is the way
to go,
Not me - I never can keep Perl operators straight.
can you provide me a basic example of how you would store thedata in a structure so I can retrieve them later?
http://servingxml.sourceforge.net/examples/index.html
has several worked out examples of flat file to XML document that
might inspire you. Once you have a DOM, you could use XPath as provided
in Java 1.5 (javax.xml.xpath package) to selectively extract values.
(a quick survey of xpath use)

If you are comfortable with Java tools for XML you might look into
this "pipeline" oriented toolkit:
http://servingxml.sourceforge.net/
The site contains examples of working with various "flat" file formats
and interconverting to and from XML.
