Question

Answer 1

To sort upper-case letters before lower-case letters, use the case-order attribute of xsl:sort.

Here's a simplified example:

Added:

I too do not understand what logic you want to implement to get the output you show.

I am able to get the same output by sorting the nodes in the following order:

• nodes that begin with initials come first;
• then sort alphabetically, ignoring case.
