<field name="cmmpServerip">
<field-validator type="requiredstring">
<message>${getText("cmmpServerip.required")}</message>
</field-validator>
<field-validator type="regex">
<param name="expression"><![CDATA[^(2[0-5]{2}|2[0-4][0-9]|1?[0-9]{1,2}).(2[0-5]{2}|2[0-4][0-9]|1?[0-9]{1,2}).(2[0-5]{2}|2[0-4][0-9]|1?[0-9]{1,2}).(2[0-5]{2}|2[0-4][0-9]|1?[0-9]{1,2})$]]></param> 
<message>${getText("cmmpServerip.size")}</message>
</field-validator>
</field>
