RE: XNI and XPath

[Ian Huynh <ia...@hubspan.com>]

I am interested in writing custom parser (eg. flat file, csv file etc)
using XNI and I have a question:

1. Once I have a parser written that implemented XNI interfaces, is it feasible 
to use XPath against the in memory document representation?

2. If so, does any one have a sample XPath that works against custom XNI parser?

Thks.

There is already a CSV parser configuration written
and included as part of the XNI samples. Check out
the CSVConfiguration class in the samples/xni/parser/
directory.

Which XPath implementation are you referring to? As
far as I know, most XPath implementations are at a
higher level (such as DOM). So swapping in the CSV
parser configuration should be transparent for the
XPath impl -- e.g. Xalan's XPath impl.
