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

<xsd:restriction base = "xsd:string"> <xsd:pattern value = "/[^']+/"/>
</xsd:restriction>

but i am not sure about the regular expression... do some research on it...
