PSVI: I/F doesn't provide length of hexBinary data
--------------------------------------------------
Key: XERCESC-1532
URL: http://issues.apache.org/jira/browse/XERCESC-1532
Project: Xerces-C++
Type: Bug
Components: Validating Parser (Schema) (Xerces 1.5 or up only)
Versions: 2.7.0
Reporter: Steve Magnani
When PSVIItem::getActualValue() is called for a hexBinary attribute,
XSValue::getActValStrings() produces a binary bytestream equivalent of the
hexBinary string. It also appends a zero byte at the end of the bytestream.
While clients are able to access the bytestream (via
XSValue::fData.fValue.f_byteVal), there does not seem to be any way for clients
to tell how many bytes are in the stream without replicating some of the logic
used by XSValue::getActValStrings(). Checking for a zero byte is not reliable,
because zero bytes are valid in hexBinary values.
Suggest making XSValue::fData.fValue.f_byteVal a struct that includes the
length of the byte stream, as well as a pointer to it.
