xml schema validate _xmldomwrapper

[amakrkr]

Hello,

i was wondering if someone could explain how this function

_XMLSchemaValidate

works:

;===============================================================================
; Function Name: _XMLSchemaValidate
; Description: Validates a document against a dtd.
; Parameter(s): $sXMLFile The file to validate
; $ns  xml namespace
; $sXSDFile DTD file to validate against.
; Syntax: _XMLSchemaValidate($sXMLFile, $ns, $sXSDFile)
; Author(s): Stephen Podhajecki <gehossafats@netmdc.com>
; Return Value(s) 1 on success or SetError(errorcode) on failure
;===============================================================================
Func _XMLSchemaValidate($sXMLFile, $ns, $sXSDFile)
;~  If not IsObj($objDoc) then
;~  _XMLError("No object passed to function _XMLSchemaValidate")
;~  Return SetError(1,27,-1)
;~  EndIf
Local $cache, $xmldoc
$cache = ObjCreate("Msxml2.XMLSchemaCache." & $DOMVERSION & ".0")
If Not IsObj($cache) Then
MsgBox(266288, "XML Error", "Unable to instantiate the XML object" & @LF & "Please check your components.")
Return SetError(-1)
EndIf
$cache.add ($ns, $sXSDFile)
$xmldoc = ObjCreate("Msxml2.DOMdocument." & $DOMVERSION & ".0")
If Not IsObj($xmldoc) Then
MsgBox(266288, "XML Error", "Unable to instantiate the XML object" & @LF & "Please check your components.")
Return SetError(-1)
EndIf
$xmldoc.async = False
$xmldoc.schemas = $cache
$xmldoc.load ($sXMLFile)
If Not ($xmldoc.parseError.errorCode = 0) Then
_XMLError("_XMLSchemaValidate:" & @LF & "Error: " & $xmldoc.parseError.errorCode & " " & $xmldoc.parseError.reason)
Return SetError($xmldoc.parseError.errorCode)
EndIf
Return 0
EndFunc   ;==>_XMLSchemaValidate

What i am trying to do is ... i would like to know if schema version has changed in XML i am using and if it has function would trigger an error.

Now as i understand _XMLSchemaValidate takes 3 parameters:

1st XML file ... i should provide here an XML object or link to a file on my local disk?

2nd xml namespace ... in my example i have this in root node:

<?xml version="1.0" encoding="utf-8"?>
<Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:edp="http://edavki.durs.si/Documents/Schemas/EDP-Common-1.xsd" xmlns="http://edavki.durs.si/Documents/Schemas/DOD_DDPO_8.xsd">

which name space should i take as parameter?

xmlns="http://edavki.durs.si/Documents/Schemas/DOD_DDPO_8.xsd"

3rd DTD file to validate against Ok this one is cleary

xmlns="http://edavki.durs.si/Documents/Schemas/DOD_DDPO_8.xsd"

If someone could clarify this for me first then i have 2 followup questions on the matter.

PS I have searched whole help forum and topic on _xmldoomwrapper and it seems noone had any problems with this function or noone uses it?

I got a feeling i can run it everytime i will do the XML and it will alter me if schema version has changed. (hopefully)
