Mukul Gandhi updated XERCESJ-1623:
----------------------------------
Fix Version/s: 2.12.0
> Invalid characters in assertion XPath expression
> ------------------------------------------------
>
> Key: XERCESJ-1623
> URL: https://issues.apache.org/jira/browse/XERCESJ-1623
> Project: Xerces2-J
> Issue Type: Bug
> Components: XML Schema 1.1 Structures
> Affects Versions: 2.11.0
> Reporter: Octavian Nadolu
> Assignee: Mukul Gandhi
> Fix For: 2.12.0
>
> Attachments:
> org.eclipse.wst.xml.xpath2.processor_2.1.2.v201212060048.jar
>
>
> If I validate the following XML Schema, I get an error:
> "cvc-xpath.3.13.4.2a: XPST0003 - Assertion XPath expression
> ('count(le:Einführung) le 1') on the schema type 'defKapitel' couldn't
> compile successfully."
> I tested on the xml-schema-1.1-dev branch.
> The error occurs because of the "ü" character that is used in the assertion.
> The problem seems to be the in the PsychoPath library
> (org.eclipse.wst.xml.xpath2.processor_1.2.0.jar) that Xerces uses.
> I updated the PsychoPath library to the latest version, 2.1.2, and the
> validation seems to work well.
> In order to make Xerces work with the new PsychoPath library, you need to
> make two modifications:
> - in XSAssertionXPath2ValueImpl.java, you need to use PsychoPathTypeHelper
> instead of PsychoPathXPathTypeHelper.
> - in AbstractPsychoPathXPath2Impl, the constructors of DefaultEvaluator and
> ElementType are modified.
