SPWeb.ProcessBatchData – Getting SharePoint to process Batches

Back in V2.0 we had a Web Service that did this sort of stuff for us, now in V3.0
it’s delivered straight from the Object Model.

Essentially:

1. We create a batch of XML which could have ‘adds, updates + deletes’ in there.
2. We call the web.ProcessBatchData(xml) method, handing to it our wishes.

This technique is fast, and CAML based 🙁

So if you need to add 100 items to the list – this would be a way to do it. (I’ve
got to check whether this technique fires event handlers on the lists or whether it’s
a ‘back door’ thing)

Note: in the snippet below, the fields are referenced via their namespace#<name>

– you can get the field’s details by saving your list ‘As a template’,
downloading the *.stp file, renaming to *.stp.cab, opening it and looking into the
*.xml file there.

– you could also call the lists.asmx webservice (..\_vti_bin\lists.asmx)
and calling the GetListCollection(); method to see a chunk of describing
XML.
