Radosław Ceszkiel updated XMLBEANS-412:
---------------------------------------
Description:
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>[email protected]</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.

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.
