RE:  RE: Ignore case while grouping
Thanks Michael for your valuable suggestions. It was indeed very useful.

As currently I am using saxon9 processor therefore the first solution is
working for me. I think there is one small issue with second solution.
It will not generate the mixed-case version that is, it will give either
ROBART J(when upper-case() is used) or robart j(when lower-case() is
used). In any case we won't get Robart J which we are getting with the
first solution.

Thanks again Michael.

The "correct" way to do this is to specify a case-blind collation, for

<xsl:for-each-group ...

Unfortunately however collation URIs are not standardised: the above URI
specific to Saxon, and you will have to to some research to discover
equivalents are available with other XSLT 2.0 processors. So a more
pragmatic solution might be to use


where EXP is your grouping key. This will work well enough in most
situations, certainly for the English alphabet.
