Hello,
I'm trying to calculate all of the groups of 2+ elements (in the sample data below, words) that appear together in more than one place. Ideally, I'd like to be able to sort descending both by length of group (5-word group, 4-word groups, etc), and by number of places the groups occur (100 places, 99 places, etc.) I also need to be able to list the place numbers where they occur. I started doing it manually this way but the number of possible combinations quickly became too big a task: <xsl:template match="/"> <xsl:value-of select="count(atlas/place/place_number[../words/word='Aa'] intersect atlas/place/place_number[../words/word='C'])"/> </template> (adding more "intersects" as necessary, and getting rid of the "count" to see the place numbers) Here's a sample of the data. Almost every word appears in multiple places, but each appears only once in the index, which I've used in other applications for matching to avoid re-calculating stats for the word over and over. Any help would be wonderful! <atlas> <place> <place_number>1</place_number> <words> <word>Aa</word> <word>C</word> <word>Qqq</word> </words> </place> <place> <place_number>2</place_number> <words> <word>Aa</word> <word>Bbbb</word> <word>C</word> <word>W</word> <word>Zz</word> </words> </place> <place> <place_number>3</place_number> <words> <word>Aa</word> <word>C</word> <word>Bb</word> <word>Qqq</word> <word>Wwww</word> <word>Zz</word> </words> </place> [etc] <index> <index_entry> <underlying_word>A</underlying_word> <word>A</word> <word>Aa</word> <word>Aaa</word> </index_entry> <index_entry> <underlying_word>B</underlying_word> <word>Bb</word> <word>Bbbb</word> </index_entry> [etc] </index> </atlas>
