[Xml-compile] Null characters in strings

[Patrick Powell]

I ran into a very odd problem today.  Due to a cut and paste update of a 
database field,  a Null (0x00) value was put into a string. This was 
then used as part of a message by the XML::Compile SOAP client.

I ran into some funny problems.   First,  one toolset generated a � 
for the null.  However,  this resulted
in an error when sent to an XML::SOAP server.  - illegal XMLchar value 0 
(I do not have the exact error message).

I then used an XML::Compile based client and looked at the SOAP message 
that was being sent.  It did not appear to have the null value in the 
string.

Question:  Does XML::Compile or its support libraries/facilties delete 
NULL characters before
doing string encoding (i.e. - translates & to &)?   Does it do this 
for other characters?

Question:  Is there a magic option/flag for XML::Compile so that it will 
ACCEPT strings with encoded
null characters in them?

Question:   If there is no way to do this,  is there 'preprocess the 
incoming message' option so that
in desperation cases the encoded NULL characters can be removed?
