Subject: [xsl] Thorny select: getting surrounding years From: Brooks Talley <brooks@xxxxxxxxxxxxx> Date: Thu, 21 Oct 2010 10:12:46 -1000 |
I've been wresting with this, and my brain is melting. I need to get a list of the surrounding years for an item -- zero to two years before, the item itself, zero to two years after. There may be gaps in the sequence, in which case I still need two items before and after (if available). Sample xml: <root> <item> <id>12345</id> <year>2005</year> </item> <otherYears> <item> <id>56789</id> <year>2001<year> </item> <item> <id>67890</id> <year>2002<year> </item> <item> <id>78901</id> <year>2003<year> </item> <item> <id>12345</id> <year>2005<year> </item> <item> <id>89012</id> <year>2006<year> </item> <item> <id>90123</id> <year>2008<year> </item> </otherYears> </root> Desired output (or similar, the select is the hard part): 2002 = 67890 2003 = 78901 2005 = 12345 2006 = 89012 2008 = 90123 Many thanks! -Brooks
