Regex validation on Tridion Schema fields and show alert message

Question

created a schema having a field name 'email'. Now i need to verify field is it valid ? if not i want to show a error message. i edit the source as follows :

<xsd:element name="email" minOccurs="0" maxOccurs="50">
<xsd:simpleType>
<xsd:restriction base="xsd:normalizedString">
<xsd:pattern value="\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*"/>
</xsd:restriction>
</xsd:simpleType>
</xsd:element>
