Mukul Gandhi commented on XERCESJ-1623:
---------------------------------------
I think, that the latest version of psychopath xpath2 engine supports unicode
(as opposed to only ASCII character set). I agree, that supporting unicode is
better since then we can use XML names having non ASCII characters.
Unfortunately, I'm not in position to commit time immediately to make these
changes to our XSD 1.1 engine. I can look at it later, if its ok. In near term
I may suggest to either,
1) simply use JRE 1.5 and use latest version of psychopath xpath2 engine. Since
we're open source, people can fork code and make a new build locally.
2) someone with keen requirement in this area, can also pursue development at
apache.
We may also have a community vote for this, on xerces devs forum.
> 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
> 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.
