Description

When default collation is declared, using starts-with function with two parameters, i.e. starts-with($arg1, $arg2), causes the error net.sf.saxon.expr.sort.SimpleCollation cannot be cast to net.sf.saxon.lib.SubstringMatcher.

There are two solutions:

  1. removing default collation declaration
  2. adding collation argument to starts-with function, for example starts-with($arg1, $arg2, "http://saxon.sf.net/collation?lang=cs-CZ")

I would expect that default collation is used for comparison within starts-with function without "redefining" it.

Am I wrong?

Example file with commented code is attached.
