#108 Pattern restriction does not work correctly with Unicode.

[Roger Dahl]

PyXB raises BadTypeValueError on some Unicode strings that should be valid according to the regular expression.

To reproduce, create TestPatternRestriction.xsd schema:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
    <xs:simpleType name="TestPatternRestriction">
        <xs:restriction base="xs:string">
            <xs:pattern value=".*"/>
        </xs:restriction>
    </xs:simpleType>

    <xs:element name="test" type="TestPatternRestriction" />    
</xs:schema>

Create binding:

pyxbgen -u 'TestPatternRestriction.xsd' -m 'TestPatternRestriction'

Create script:

1 2 3 4

#!/usr/bin/env python # -*- coding: utf-8 -*- import TestPatternRestriction as t xml=u"

[Roger Dahl]

Trac truncated the submission at the location of the Unicode character in the example script. Here is the script again, this time with the unicode character represented as a \u escape sequence:

1 2 3 4 5 6

#!/usr/bin/env python # -*- coding: utf-8 -*- import TestPatternRestriction as t xml=u"\U00010314"; p = t.TestPatternRestriction(xml) print p.toxml()

Error message (even though the ".*" regular expression in the restriction should match the Unicode character:

BadTypeValueError(u'pattern violation for \U00010314 in TestPatternRestriction',)
