Hi all
I am new to ada. I am working on a project where I am parsing XML for data. I am trying to validate the XML received (I am receiving XML from third party) using the schema module. Following is the sample schema which I took from w3c site after I was getting raised CONSTRAINT_ERROR : schema-validators.adb:2166 invalid data for my own schema but I am getting same error for this schema.
<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="note">
<xs:complexType>
<xs:sequence>
<xs:element name="to" type="xs:string"/>
<xs:element name="from" type="xs:string"/>
<xs:element name="heading" type="xs:string"/>
<xs:element name="body" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
Changing the version and scheam tag to
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified"
targetNamespace="http://example.com/schemas/agent"
xmlns:agent="http://example.com/schemas/agent">
does not make any difference. I tried looking into schema-validators.adb but that was of no use. Please help.

I think you need to post your code.
Try to make a small compilable sample that reproduces your error
and post is here.

Also, neither of the versions of XML/Ada that I have to hand has code at
that line which looks as though it could raise that exception at that
line. Which version are you using?

The above code is what I have used in my xsd and I am following the Ada documentation to generate grammar.
I have put my xsd code aside just to figure out what is the reason for error as it is same in both the scenarios.
I am using GNAT 4.6 so it should be Ada 2005.
Is it possible that it is due to some dependency or version clashes?

Maybe - or it is your code. But since you don't show your code
it is impossible to tell...

GCC 4.6 sounds like debian wheezy.

I've got a couple of xml/ad versions
one is gpl 2014, the other I do not know - I think it
was bundled with a late-ish gnat pro.
One (gpl) points at function
function Dump_Dot_NFA
for line 2166
the other points 1 row above
function Get_Key
(Group : XML_Group) return Unicode.CES.Byte_Sequence is
I think you need to show your line 2166. and the surounding lines.
and your link commands - and the gpr file.
I cannot really see anything wrong

It is function Dump_Dot_NFA at line 2166.
I am using gnatmake filename.adb `xmlada-config` for linking.
I don't have any gpr file.

using that command and gnat gpl 2014 x64
work fine here.
I do have a gnat fsf 4.9, but I do not have a gnat fsf 4.6 anymore.
I'd try to install gnat gpl 2014 if it is possible.

I cannot uninstall gnat. I have tried sudo apt-get remove gnat and sudo aptitude remove gnat gnat4.6. And due to this I cannot install gnat4.9 as it is conflicting with earlier version. How do I remove gnat4.6 so as to install 4.9?

Note that I did not write that I got it to work with 4.9.
It should of course.
It seem like you have os-trouble.
sudo apt-get remove gnat
sudo apt-get install gnat-4.9
Should have done it, I think.
Another way is to install gnat gpl, and put it first in your path.
it is not a apt install, but a shell script, putting the compiler in
a directory of your choise. Easy to remove if you want to.
