Validating topic via MSXML4 using DITA 1.3 DTD

Post by **tmakita** » Mon Oct 10, 2016 3:29 pm

Hi All,

This may be not concern editing or publishing DITA content. But it concerns DITA content validation.

I have been developing DITA 1.3 specializations by RELAX NG and now I began making DTD specializations. In my validation testing Xerces works well because it uses catalog files. However validating with MSXML4 fails with strange error.

So I back to basic testing. When I make following DITA topics and validate it with MSXML4, it reports validation error.

[test-dtd-topic.dita]

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE topic PUBLIC "-//OASIS//DTD DITA Topic//EN" 

"C:\Program Files\Oxygen XML Editor 18\frameworks\dita\DITA-OT2.x\plugins\org.oasis-open.dita.v1_3\dtd\technicalContent\dtd\topic.dtd">

<topic id="topic_uhz_gdp_pt">

  <title>Topic example</title>

  <body>

    <p>Paragraph with <ph>ph</ph></p>

  </body>

</topic>

The reported message is very vague. So I used following .vbs file and invoked from Windows 10 command prompt (32bit).

Code: Select all

if WScript.Arguments.Count < 1 then

  MsgBox "missing XML file parameter!"

else

  call parse()

end if



Sub parse()

	Dim objParser

	Dim objParserError

	

	Set objParser = CreateObject("MSXML2.DOMDocument.3.0")

	objParser.async = False

	objParser.validateOnParse = True

	objParser.resolveExternals = True

	objParser.SetProperty "ProhibitDTD", False

	If Not (objParser.Load(WScript.Arguments(0))) Then

		Set objParserError = objParser.parseError

		With objParserError

			stMsg = "#### VALIDATION ERROR ###"& vbCrLf

			stMsg = stMsg & "Error code: " & hex(.errorCode) & vbCrLf

			stMsg = stMsg & "Reason: " & .reason & vbCrLf

			stMsg = stMsg & "Line: " & .Line & vbCrLf

			stMsg = stMsg & "Line position: " & .linepos & vbCrLf

			stMsg = stMsg & "Source text: " & .srcText & vbCrLf

			stMsg = stMsg & "URL: " & .URL & vbCrLf

		End With

		WScript.StdOut.Write stMsg

	else

		WScript.StdOut.Write "Validation succeeded!"& vbCrLf

	End If

	Set objParser = Nothing

end sub

The result is as follows:

Code: Select all

C:\WINDOWS\SysWOW64>cscript C:\Users\toshi\OneDrive\Documents\DITA-test\validate

4.vbs C:\Users\toshi\OneDrive\Documents\DITA-test\test-dtd-tppic.dita

Does anyone has succeeded to validate your topic via MSXML4 using DITA 1.3 DTD? Or is this known problem?

Any information is welcome.

For your reference, this error does not changed even if I tested the following topic. This topic uses the newest DITA-OT.

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE topic PUBLIC "-//OASIS//DTD DITA Topic//EN" 

"D:\DITA-OT\dita-ot-2.3.3\plugins\org.oasis-open.dita.v1_3\dtd\technicalContent\dtd\topic.dtd">

Dear Toshihiko Makita,

The forum is a more static place, users mostly follow the threads that they started so if you want an opinion from the community you should write on the DITA Users List if the problem is DITA specific or on the Oxygen users list if the problem also involves Oxygen.
I looked a little bit into this and MSXML seems to be right, in the DTD svg11-flat-20110816.dtd there is a parameter entity reference %svg-prefw-redecl.mod; but the parameter entity is not defined anywhere. So it probably depends on how each XML parser handles this type of problem, probably Xerces ignores it completely.
I think Eliot Kimber is the one who added this DTD in the set of DITA OT DTDs in order to support inline SVGs.

Regards,
Radu

Hi Radu,

Thank you for your reply and investigation.
Yes, I will post this problem to dita-users as the common problem of DITA 1.3 DTD.
