I've been trying to think through a problem and Im hoping for
a little help. Here's the scenario:
I have complex nested XML data that is wrapped by subsequent
groupings for efficiency, but I need to determine if each inner
item belongs in the data collection for view in a data grid and
I've posted an example at the bottom.
So the goal here is to first be able to select a single
inspector and then chart out their reports. I can get the data to
filter from the XMLListCollection using a filter on the first layer
(ie the name of the inspector) but then can't get a filter to go
deeper into the structure in order to determine if the individual
item should be contained inside the collection. In other words, I
want to filter by inspector, then time and then tag name in order
to be able to use this data as the basis for individual series
inside my advanced data grid and column chart.
I've made it work with creating a new collection and then
looping through each time there is a change to the original
collection and updating the new collection, but that just feels so
bloated and inefficient. The user is going to have some buttons to
allow them to change their view. I'm wondering if there is a
cleaner way to approach this? I even tried chaining filter
functions together, but that didn't work cause the collection is
reset whenever the .refresh() is called.
If anyone has experience in efficiently dealing with complex
XML for charting purposes and tabular display purposes, I would
greatly appreciate your assistance. I know I can get this to work
with a bunch of overhead, but I'm seeking something elegant.
