we are using XMLMind Professional Edition 9.5.1 and I have a question regarding 
files that have no DTD but should have one.

I have to add a DTD to these files. Is it possible to write a command that 
saves the currently opened file, adds a dtd (maybe via xslt transformation?) 
and reloads it in XMLMind, so that the user works on the latest version of this 
file?

The answer is almost certainly YES, but it will not be easy becausethere is an awful lot of XXE techniques to master.

We won't help you writing or debugging such advanced macro-command(probably invoking a process command) as it is completely out of thescope of normal support.


Some pointers though...

1) The following command is found inXXE_install_dir/config/addon/docbook/docbook.xxe.

It converts the currently DocBook v4.x document to v5.0 or v5.1 by (A)invoking a XSLT stylesheet called "db4-upgrade.xsl" (part of the DocBookXSL stylesheet distribution) and then (B) opening in XXE the resultingDocBook v5 file using command "XXE.open":

  <macro>
    <sequence>

<set variable="converted" expression="uu:setExtension('%d','db5.xml')"

           xmlns:uu="java:com.xmlmind.util.URIComponent" />

      <get expression="$converted" />
      <command name="selectFile"
               parameter="[DocBook 5 Save File] saveFileURL %_" />
      <set variable="converted" expression="%_" plainString="true" />

      <choice>
        <sequence>
          <test expression="$converted = '%d'" />
          <command name="alert"

                   parameter="'Which DocBook version?'
                              false '&quot;5.0&quot;' '&quot;5.1&quot;'" />
          <set variable="params"

          <get expression="$params" />
          <command name="{docb}.convertToV5" parameter="%_" />

          <command name="XXE.open" parameter="[reopen]" />
        </sequence>
      </choice>
    </sequence>
  </macro>
</command>

<command name="{docb}.convertToV5">

  </process>
