xs:pattern allows unallowed token

[SaschaF.]

Hello.

I defined the following pattern for evaluating a date-string:

Code: Select all

([0-9]{4}\-[0-9]{1,2}\-[0-9]{1,2})?

IMHO this should only allow something like 2009-03-12 or nothing!

But the XML-Validation (all engines) allows the following chars: a, e, n, p, r and t

i.e.

Code: Select all

<tag>a</tag>

is allowed.

Whats that

Btw: Oxygens inplaced RegEx-Konstruktor does not have this behavior.

Hello,

I tested your pattern in Oxygen both in the XML Schema regex builder tool (available on the Tools menu) and in an XML document validated against an XML Schema that specifies the pattern. It works correctly. Illegal characters like a, e, n, p, etc are reported as error. Can you post a sample schema for reproducing the problem?

XSD

Code: Select all

?xml version="1.0" encoding="UTF-8"?>

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

    <xs:element name="TEST">

        <xs:complexType>

            <xs:sequence>

                <xs:element name="FIELDVALUE">

                    <xs:simpleType>

                        <xs:restriction base="xs:string">

                            <xs:pattern value="[pattern]"/>

                            <xs:pattern value="(\d{4}\-\d{1,2}\-\d{1,2})?"/>

                        </xs:restriction>

                    </xs:simpleType>

                </xs:element>

            </xs:sequence>

        </xs:complexType>

    </xs:element>

</xs:schema>

XML

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>

<TEST xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:noNamespaceSchemaLocation="Test.xsd">

    <FIELDVALUE>a</FIELDVALUE>

</TEST>

<oXygen/> XML Editor 10.1, build 2009022414

Code: Select all

<xs:simpleType>

  <xs:restriction base="xs:string">

    <xs:pattern value="[pattern]"/>

    <xs:pattern value="(\d{4}\-\d{1,2}\-\d{1,2})?"/>

  </xs:restriction>

</xs:simpleType>

The two patterns are ORed, not ANDed which means the following values are accepted: p, a, t, e, r, n, 2009-03-12, 1863-3-6, etc.
