 I'm wondering if anyone has created a template (or has ideas on how to efficiently create such) that generates a list of items that is missing from a given source document. Assume that a node-set is passed that contains an assorted cluster of indices, the template should start at one, and continue to the highest provided element, outputting all missing elements. For example, the source document: <root> <obj><childnode>3</childnode></obj> <obj><childnode>5</childnode></obj> <obj><childnode>9</childnode></obj> <obj><childnode>5</childnode></obj> <obj><childnode>4</childnode></obj> <obj><childnode>1</childnode></obj> <obj><childnode>7</childnode></obj> </root> might produce <missing> <obj><childnode>2</childnode></obj> <obj><childnode>6</childnode></obj> <obj><childnode>8</childnode></obj> </missing> when passed through such a template. I figure one way to do this is to first sort the node-set (possibly using a parameter to identify the indexed node), and then apply a template on all children that don't have an index that is 1 less than that of the following sibling. But there are problems there when there are 2 consecutively missing nodes. Any ideas?
