Can I specify in XSD for not accepting a particular pattern

Hi,

I am validating my XML file by means of an XSD. Can I specify in

the XSD for not accepting a particular pattern.

I don't want to accept the string containing pattern "'".

Becuase if it tries to get inserted into database error will occur.

Thanks in advance
