ASCII characters

Sat Jan 15, 2005 3:03 am

Hi,
I have a string(6-240 characters) for which I need to check that each of the characters is a valid ASCII character. Any ideas?

Thank You,

Ilan

Hi,

You can have something like:

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:element name="test" type="test"/>
    <xs:simpleType name="test">
        <xs:restriction base="xs:string">
            <xs:pattern value="(\p{IsBasicLatin})*"/>
            <xs:maxLength value="240"/>
            <xs:minLength value="6"/>
        </xs:restriction>
    </xs:simpleType>
</xs:schema>


This will accept between 6 and 240 ASCII characters as the content of the test element.

Hope that helps,
George
