Fine ... I'll assume the interweaving and separation you desire is in document order of the original in each case. >I know I can apply a cludge to solve the above problem.

No kludge necessary ... just make two passes of the source tree (visiting only the nodes you desire) in a single stylesheet. >However, this still leaves the reverse problem of translating from a tag >order of AAABBB to ABABAB.

Again, I'll assume you want to preserve the document order of the input in the elements of the output ... if you want another order than document order, the example below won't show that. I've added attributes to the elements to illustrate the ordering. I've also illustrated using different numbers of A and B, though it also works with the identical number. I hope this helps. ............
