RE: [xsl] Unusual Sort

David, *I* didn't ask the question, but nice, especially because the XSL is simply a concretization of a way of approaching a problem.

I'm reminded of a problem presented to Ken Thompson (the UNIX guy): find which words in a list are anagrams of one another. His solution was beautifully elegant, especially for its simplicity. It consisted of the following:

--for each word, generate a "key"--which is simply a word consisting of the original word's characters sorted. Eg. for word "apple", the key is "aelpp"
--sort list based on key
--extract groups of keys; their corresponding words are anagrams of one another

And this is succintly expressed as an UNIX pipeline.

Anyway, your <xsl:sort select="translate('FSJ','ABC',grade)"/> gives me a similar feeling!

I was wondering if there is any way to sort elements other than just the
regular alphabetical order.  For example,  If you wanted to sort grade
levels (Freshman, Sophmore, Junior, etc)  so that they are displayed in the
correct order and not the alphabetical order (Freshman, Graduate, Junior,
Senior, Sophmore). This is an optional piece of my application so if It
can't be done fairly easily I will probably not worry about creating the
functionality of the sort on page..in other words if it's a huge deal don't
worry about going to the trouble of creating the sort.. Just let me know.

Thanks

Chris

<xsl:sort select="translate('FSJ','ABC',grade)"/>
