Re: Discrepancy in handling current() in a pattern
here is what I am trying to do. ... <!-- First "stack" of matching for vertical lines --> <!-- This matches cells that have a vertical lines on their left -->
If you are at the top left cell, then won't both of the above template rules match the cell you are at? That would be ambiguous and Saxon is right to report an ambiguous template rule match.
So my questions: --------------- 1) Because of the discrepancy I noticed between Firefox and I.E, my first question is: "Is current() allowed or not in an XSLT1.0 pattern?" (or maybe it is "implementation defined or dependant" but XSLT1.0 is unclear about that... or I couldn't find it!)
I see in XSLT 1.0 Section 12.4 the following:
"It is an error to use the current function in a pattern."
2) Is is allowed in XSLT2.0 -should be because Saxon do not complain about current() itself, but about its type-, and what is the correct expression to remove the recoverable error?
I see in XSLT 2.0 Section 16.6.1 the following:
"If the current function is used within a pattern, its value is the node that is being matched against the pattern."
Therefore the return type is a node (and I trust Michael to have implemented Saxon correctly in this regard), so I don't think the recoverable error is type related at all. As I cite above I'm pretty sure from your code's documentation (I could not take the time to read the detailed code) that the top-left cell is going to satisfy the criteria for both template rules. That would be ambiguous, and recoverable.
/Although I would probably try to code this puzzle differently in 2.0, using for example a for-each-group/
No comment (can't take the time to analyze your logic, sorry).
I hope this helps.
