MSXML
does not have a Schematron validator. You will need to use some separate code or
a dedicated Schematron processor. I use the Schematron skeleton XSLT to create
an XSLT file, then process the document using this. In a test environment,
you can just use transformNodeToObject to create the stylesheet, then
transformNode to provide a validation output. I have not tried
the skeleton with embedded Schematron - you might need to modify
it slightly or pre-process your schema to pull out the Schematron
parts.
In a
production environment, you would probably want to do the first transformation
once only, then store the result. A quick google will find the skeleton and
names of Schematron processors.

Hi
everybody,
i've searched in the archive for an answer but couldn't find
it so let me ask the following question :
I've learned how to embed
basic Schematron patterns in W3C XML Schema but couldn't find how to validate
it with MSXML (4.0 or 6.0) parser programmatically.
Dim objSchemaCache
As New MSXML2.XMLSchemaCache60
Dim objXMLDoc As New
MSXML2.DOMDocument60
objSchemaCache.Add "", nameOfSchemaFile
Set
objXMLDoc.Schemas = objSchemaCache
objXMLDoc.async =
False
objXMLDoc.Load nameOfXMLFile
' I raise the error if it exist
with :
If objXMLDoc.parseError.errorCode <> 0
With a simple
schema it works marvellously well but the problem is that the parser doesn't
seem to "recognize" the Shematron pattern embedded in my Schema.
I used
basic xml and xml schema to test it, here are the following files :
the
xml file :
<?xml version="1.0" encoding="UTF-8"?>
<AAA
xmlns:sch="http://www.ascc.net/xml/schematron"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="C:\Documents and
Settings\samuel\Bureau\outil_statistiques\XML\ambiguite_shematron\ambigu1.xsd">
<BBB>
<CCC>0</CCC>
<CCC>0</CCC>
<CCC>0</CCC>
</BBB>
</AAA>
the schematron+w3c xml schema file
:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema
xmlns:sch="http://www.ascc.net/xml/schematron"
xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:simpleType name="CCCType">
<xs:restriction base="xs:byte">
<xs:enumeration value="0"/>
<xs:enumeration
value="-1"/>
</xs:restriction>
</xs:simpleType>
<xs:element
name="BBB">
<xs:annotation>
<xs:appinfo>
<sch:pattern name="Sum inf
-1">
<sch:rule
context="//BBB">
<sch:assert test="sum(//CCC) = 0">0
result</sch:assert>
<sch:assert test="sum(//CCC) < 0">under 0 result
</sch:assert>
</sch:rule>
</sch:pattern>
</xs:appinfo>
</xs:annotation>
<xs:complexType>
<xs:sequence>
<xs:element
name="CCC" type="CCCType" maxOccurs="3"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element
name="AAA">
<xs:complexType>
<xs:sequence>
<xs:element
ref="BBB"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
I'd like to raise the fact
that the sum is equal to 0 but cannot catch it.
If you can
help...
thanks
sam
