      org.ucl.xpath.function.FnSubsequence

public class FnSubsequence

extends Function

Returns the contiguous sequence of items in the value of $sourceSeq beginning at the position indicated by the value of $startingLoc and continuing for the number of items indicated by the value of $length. More specifically, returns the items in $sourceString whose position $p obeys: - fn:round($startingLoc) <= $p < fn:round($startingLoc) + fn:round($length)
