CLONE -Pattern facet regex requires dash - to be escaped
--------------------------------------------------------
Key: XMLBEANS-412
URL: https://issues.apache.org/jira/browse/XMLBEANS-412
Project: XMLBeans
Issue Type: Bug
Components: Validator
Affects Versions: Version 2
Environment: Win 2000, JDK1.5
Reporter: Radosław Ceszkiel
Fix For: Version 2
Given the following xsd that should allow only a valid email address pattern:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema";>
<xsd:element name="Email" type="EmailType" />
<xsd:simpleType name="EmailType" >
<xsd:restriction base="xsd:token">
<xsd:pattern
value="([\.a-zA-Z0-9_-])+@([a-zA-Z0-9_-])+(([a-zA-Z0-9_-])*\.([a-zA-Z0-9_-])+)+"/>
</xsd:restriction>
</xsd:simpleType>
</xsd:schema>
Using the following simple xml instance:
<Email>t...@test.com</Email>
Running:
validate sample.xsd sample.xml
generates:
Schema invalid:
D:\sample.xsd:7: error: pattern-regex: The regular expression
'([\.a-zA-Z0-9_-])+@([a-zA-Z0-9_-])+(([a-zA-Z0-9_-])*\.([a-zA-Z0-9_-])+)+' is
malformed: '-' is an invalid character range. Write '\-'.
Question: Why should I have to escape the dashes??
Then escaping the dashes, you can actually get the schema to compile. But then
you have a new problem. The regex does validate valid email addresses!!
So two bugs AFAIK - shouldn't need to escape slashes. Something in the regex is
not recognised by xmlbeans regex parser.
