Please provide any additional information below.
See postings to the schematron-love-in mailing list
(https://lists.sourceforge.net/lists/listinfo/schematron-love-in) of today
with subject 'canonical method to say "pointing to a <foo>"'.

It appears, but is perhaps not very meaningful.

User has requested allowing specification of multiple phases per run.

IMHO, the current version of Probatron4J is specifically designed for
command line usages. It is not very usable from the java code.

The expectations that I have from Probatron4J is -  
  Should take a xml document and schematron schema, validate the document
against schema and return result in the form of an object. 
The object (say ValidationResult) should have a method which tells whether
validation is successful and another method to return list of error messages.

I tried to use the SchematronSchema class to do the validation for me.
The problems that I faced are -
1. The SchematronSchema.validateCandidate(URL url) method takes URL of the
candidate xml document. This is useful if the xml to be verified is a file
or URL. However, in the java code, the xml is likely to be in the form of a
String or stream. There is no way to convert string to URL, without
writting the string to a file and its a bad solution.

SchematronSchema has a validateCandidate(InputStream is) method, but it is
private.

2. After validation, validateCandidate() method returns ValidationReport
object which holds the bytes for the complete report XML. There is no class
in probatron jar which helps to retrieve error messages from this report XML.

Solutions that I propose - 
1. Make SchematronSchema.validateCandidate(InputStream is) method public,
so that xml which is in the form of String can be passed for validation. We
can also create a overloaded method which takes string.

2. Provide a mechanism to get the validation result in the form of a object
with the list of error messages. 
To do this, we need to create a Document object from the result stream and
then apply the XPath '//failed-assert/text/text()' to get the error messages.


I am using 0.7.1 version of Probatron4J.

Please let me know your opinion. I can provide the patch for the required
changes.

Hi,

At line 59, of the Utils.java, it changes the system property 
'javax.xml.transform.TransformerFactory'

 System.setProperty( PROPERTY_TRAX_IMPLEMENTATION, SAXON_TRAX_CLASS );

It creates problem when the system uses another impl. TransformerFactory.

It is unexpected behavior and creates side-effect

Kind regards

For version 0.7.0, <failed-assert> elements have bad XPaths (i.e. they
cointain the Namespace URI in curly brackets rather than a prefix). 

What steps will reproduce the problem?

1. Schema (testSchema.sch) contains:

<schema xmlns="http://purl.oclc.org/dsdl/schematron">
  <include href="testSchema-include.sch"></include>
  <pattern name="...">...</pattern>
</schema>


2. Included schema contains

<pattern name="..." xmlns="http://purl.oclc.org/dsdl/schematron">...</pattern>

3. Run probatron:

java -jar "probatron.jar" testDocument.xml testSchema.sch 

4. Try again with absolute file path in the @href attribute (both
"file:/C:/..." and "file:///C:/...")


What is the expected output? What do you see instead?

Error message appears:

Recoverable error on line 359 
  FODC0002: java.net.MalformedURLException

Unable to open referenced included file: testSchema-include.sch
Unable to locate id attribute: testSchema-include.sch

Then the output of just the <pattern> in the main schema appears.


What version of the product are you using? On what operating system?

Probatron4j 0.7.1
Java 1.6.0_03
Windows XP Professional SP 2


The schema was successfully compiled with Saxon using the standard
iso_dsdl_include.xsl stylesheet

I'm using probatron programatically in a jar, with the schematron file
included. Inside the schematron, I'm using a reference to another file that
contains a list of accepted values :

<iso:report test="document('./annex.xml')...>

When running probatron from the command line, with the schematron and
include file in the same folder, I have no issues at all.

However, when I try to use it programatically, the schematron.sch and
annex.xml files are located in :

src/main/resources/sch/

After the build, the classes folder structure is as follows :

bar/foo/myClass.class
sch/schematron.sch
sch/annex.xml

Within the code, I use the following to set the schemadoc :

    URL schemaLocation =
SumehrValidator.class.getResource(SCHEMATRON_FILE_NAME);
    theSession.setSchemaDoc(schemaLocation.toString());

Now, when I perform theSession.doValidation(filename), I get a
FileNotFoundException :

Recoverable error on line 1011 
  FODC0002: java.io.FileNotFoundException:
  C:\eclipse\workspace\bar\foo\annex.xml (The system cannot find
  the file specified)

As the included file is in the same directory as the schematron file, is
there a way to prevent the system from looking in the jar's root folder ?

What steps will reproduce the problem?
1. Schema (spatialObservation.sch) contains
    <xsl:import-schema
        schema-location="http://schemas.opengis.net/gml/3.2.1/gml.xsd"/>
    <xsl:import-schema
        schema-location="http://schemas.opengis.net/om/2.0/observation.xsd"/>
2. Run probatron:
  java -jar probatron.jar spatial_observation1.xml spatialObservation.sch
3.

What is the expected output? What do you see instead?
   probatron only support Basic XSLT Processor  ?

Error at xsl:import-schema on line 34 column 87

Hello,

I need to validate an xml file using a xslt transformer and of course a 
schematron schema. When I try to run probatron.jar without my custom xslt file, 
it gives me that error :

I also need to run validation through java code, I have tried some samples but 
I couldn't manage to run validation for my local xml and schema from code. Can 
you please show me a snippet to run validation. Thanks in advance.

i have a schematron file and xml file. 
What is the expected output? What do you see instead?
i need to see schematron error but not found

What version of the product are you using? On what operating system?
0.7.4

Please provide any additional information below.
at the schema there is a rule 
<assert test="not(gl-cor:documentNumber) or gl-cor:documentType">error</assert>

the first entry detail have that condition buth probatron not found it.

tried to run

java -jar probatron.jar

Collides with supposed unique string substitution values used internally

With a document such as

<foo bar='blort'/>

and schema rule

<rule context='@bar'>
  <report test='.'/>
</rule>

the node is reported as e.g. 

<successful-report test='.' location='blort'/>

currently is app folder; probably should be schema document (spec?)
