Chris Simmons commented on XERCESJ-1361:
----------------------------------------
Thanks. We're actually using our own repackaged version of Xerces, the com.sun
stuff was just confusion.
I've found that we have to use the (repackaged) Xerces implementation directly
as there's no way of getting line/column information for the elements using the
DOM api's AFAIK. I'd be glad to be corrected if I'm wrong though!

> Project: Xerces2-J
> Issue Type: Bug
> Components: DOM (Level 3 Load & Save)
> Affects Versions: 2.9.1

> If there are multiple text node children on an element (which, in this case
> given below, results from filtering elements during parsing) then the
> element in the DOM on output contains only the final text node:
