[jira] Commented: (XMLBEANS-412) CLONE -Pattern facet regex
requires dash - to be escaped
[ https://issues.apache.org/jira/browse/XMLBEANS-412?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12875542#action_12875542 ]
Julien HENRY commented on XMLBEANS-412:
---------------------------------------
I can confirm this is a bug in xmlbeans.
According to the spec, [A-F0-9.+-]* is a valid regular expression but xmlbean fails with:
error: pattern-regex: The regular expression '[A-F0-9.+-]*' is malformed: '-' is an invalid character range. Write '\-'.

> 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>test@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 '\-'.
> A dash at the end or at the beginning of a character range does not have to be escaped (see http://www.w3.org/TR/2004/REC-xmlschema-2-20041028/datatypes.html#nt-charRange "The - character is a valid character range only at the beginning or end of a - positive character group- .")
> The regular expression in the email example is a valid xsd regexp and should be accepted by the XmlBeans validator.
