The declaration looks to be correct from what I can see. I have gone over this several times and can't come up with anything. Any thoughts?

  • you haven't provided many details as to what you are actually doing, but is it possible you are parsing using a parser which is not namespace aware? Commented Sep 4, 2012 at 17:52
  • SAX Parser is namespace aware Commented Sep 4, 2012 at 17:59
  • The schema looks fine. Can you please post/check the relevant parts of xnat.xsd and xdat.xsd ? Commented Sep 4, 2012 at 18:22
  • @user1332868 - are you saying that you configured your SAXParser to be namespace aware (it's not configured that way by default)? Commented Sep 4, 2012 at 20:09
  • it would be helpful if you showed some example code and maybe what you are trying to parse. Commented Sep 4, 2012 at 20:10

Your declaration is invalid. You are missing a space before targetNameSpace.

problem in spacing it should be

<?xml version="1.0" encoding="UTF-8"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://nrg.wustl.edu/tx" xmlns:tx="http://nrg.wustl.edu/tx" xmlns:xnat="http://nrg.wustl.edu/xnat" xmlns:xdat="http://cnl.wustl.edu/xdat" elementFormDefault="qualified" attributeFormDefault="unqualified">
