Re: XML Pipeline

["Stephen E. Beller" <sbeller@nhds.com>]

I thank you all very much for the links.

They don't seem to do what I need, however.  Maybe I wasn't specific enough.

I have numbers in arrays and lists that I ultimately want to render as
graphs. These data "evolve" as they pass through a pipeline of a network of
"nodes" -- going from computer to computer, some being manned by people and
some run by automated software agents. Each of these nodes has a role. 

The role of some nodes is to add data to one or more of the arrays, putting
data values in certain pre-defined positions in the arrays so, when the data
are ultimately parsed and rendered, the graphs are properly formatted. From
these nodes, the data may manually input, sent directly via a database
query, extracted from another XML document, input from a sensor via an I/O
port, etc. 

Other nodes are responsible for evaluating/validating the data and changing
certain data elements in the arrays and/or lists when necessary.

Other nodes must perform computations on certain data, including data
aggregation, statistical analysis, and other forms of data mining/analytics.
These test results must be incorporated into the arrays in pre-determined
positions and/or added to the lists.

And finally the evolved arrays and lists are received by a node that must
render them in multiple offline-interactive reports, as well as having the
data available for ad-hoc computations/analytics.

I want this process to be as quick and efficient as possible. 

I realize this is a tall order, and still wonder how XML can help.

Thank you, again.
