The confusion is exarcebated by the fact that Java based parsers are doing Normalization which returns values which I have mentioned that are

No that was libxml2 bugs :-\ . They were a bit hard to fix, but hopefully they are fixed in SVN, could you please checkout and rerun your tests. I have tried to include your examples in the regression suite, and also fixed the over normalization issue you raised earlier.
I hope this is fine now,
Thanks for the fixes!!!
However there seems to be a slight problem in xmlAttrNormalizeSpace2...
When this function is called in xmlParseAttribute2..
val2 = xmlAttrNormalizeSpace2(ctxt, val, len);
if (val2 != NULL) {
xmlFree(val); // Here if only leading spaces are present
val = val2; //xmlAttrNormalizeSpace2 returns the pointer to the first
char after the leading spaces, so in this case val2
will point to the same memory as val except it will be
ahead by the number of whitespaces....
So freeing val will in effect free val2 as well, and thus will lead to
problems.
I am attaching a patch which takes care of the problem. Please let me know
if this is ok.

Ashwin
