Hi,
I have got an xml file and an XSD. I am validating xml file writing all the rules in xsd.
Suppose I want to check whether the character '@' is there in the email attribute of xml file.
with regards

hi,
you can add something like the following restriction in your schema to make sure if it is a valid email address.
<xsd:restriction base="xsd:string">
<xsd:maxLength value="128"/>
<xsd:minLength value="5"/>
<xsd pattern value="^[\w-_\.]*[\w-_\.]\@[\w-]+\.[\w-_\.]+$"/>
</xsd:restriction>

Ho,
thanyou very much. Can u please give me the details of this pattern
<xsd attern value="^[\w-_\.]*[\w-_\.]\@[\w-]+\.[\w-_\.]+$"/>
Like what is the correct value according to this pattern.
If I want to replace this email format with a different number
which contains numbers and an hyphen anywhere in the value,
how should i write this
thanks and regards
