Re: updating datasets on Las

[Jonathan Callahan <callahan@xxxxxxxxxxxxx>]

Mark,

I'm cc'ing my response to the LAS users' group where such questions
should be directed.  The questions and answers are archived there for
others to find.

First off I recommend that everyone use XML includes to keep their
dataset XML in separate files.  An FAQ describing this exists here:

http://ferret.wrc.noaa.gov/Ferret/LAS/FAQ/xml_includes.html


Using XML includes allows you to separate the XML files for each dataset
so that you don't need to use delXml.pl -- you simply remove my_data.xml
and regenerate it.  It looks like you have the rest of it working.

I'm sure that there would be many people interested in any
semi-automated solutions you come up with for scheduled updates of the
LAS interface.  You're not the only one to confront this problem.

PS__ We'd love to have a look at your LAS site.  What's the URL?
