I chose to set it to pending as I believed I had fixed the problem. I knew the tracker would close it after 14 days. The idea is to give you (the submitter) a chance to confirm or deny the fix. In this particular case, it might be difficult to test/demonstrate the fix, because of the status of support for SE in the XPath library.

From what I can see, it looks like we call XM_XSLT_OUTPUT_ENCODER.is_valid_string with a string that contains a Null character. This routine then calls `is_bad_character_code' which has a precondition `is_char'. But `is_char' returns False when the code is zero. So my guess is that either `is_char' should return True when the code is zero, or `is_valid_string' should make sure to call `is_bad_character_code' only after having checked that `is_char' holds (or both). > > > > ---------------------------------------------------------------------- > > > >> Comment By: SourceForge Robot (sf-robot) > > Date: 2008-02-02 19:20 > > > > Message: > > Logged In: YES > > user_id=1312539 > > Originator: NO > > > > This Tracker item was closed automatically by the system.
