> Key: XERCESJ-1061
> URL: http://issues.apache.org/jira/browse/XERCESJ-1061
> Project: Xerces2-J
> Issue Type: Bug
> Components: XML Schema datatypes
> Affects Versions: 2.6.2
> Environment: Test Environment: Win XP SP1, JDK v1.5.0_02, Xerces
> v2.6.2 (manually used; overrides any other, if packaged with the JDK)
> Reporter: Darien Kindlund
> Priority: Minor
> Attachments: RegexParser.diff, regexparser.java
>
>
> Xerces rejects the following schema:
> <xs:schema xmlns:xs='http://www.w3.org/2001/XMLSchema'>
> <xs:element name="test">
> <xs:simpleType>
> <xs:restriction base="xs:string">
> <xs:pattern value="$?[0-9]+\.[0-9]{2}" />
> </xs:restriction>
> </xs:simpleType>
> </xs:element>
> </xs:schema>
> The code within org.apache.xerces.impl.xpath.regex.RegexParser throws a
> parser exception over the use of the "$?" characters, unless the "$"
> character is escaped. For example, this works:
> <xs:pattern value="\$?[0-9]+\.[0-9]{2}" />
> The fundamental problem is that the Xerces RegexParser code does NOT follow
> the XML Schema specification, as defined by this URL:
> http://www.w3.org/TR/2000/WD-xmlschema-2-20000407/#dt-metac
> Specifically, the XML Schema specification does NOT give special meaning to
> the "$" and "^" characters, whereas the RegexParser code seems to indicate
> that these characters have the normal, standard UNIX definitions of
> "end-of-line" and "start-of-line" anchors respectively.
