As an alternative to using the iXML grammar to parse it, you could 
usehttps://johnlumley.github.io/jwiXML.xhtml

Load the grammar into the grammar panel and press *GO!* - you should get 
a display of the parsed grammar - just press '*select grammar*' to 
highlight it and then copy the selection. It gives, as Norm's does:

    <ixml>
        <rule name="numbers">
           <alt>
              <nonterminal mark="@" name="source"/>
              <repeat0>
                 <nonterminal name="n"/>
                 <sep>
                    <literal tmark="-" string=", "/>
                 </sep>
              </repeat0>
           </alt>
        </rule>
        <rule name="source">
           <alt>
              <insertion string="ixml"/>
           </alt>
        </rule>
        <rule name="n">
           <alt>
              <nonterminal name="neg"/>
           </alt>
           <alt>
              <nonterminal name="pos"/>
           </alt>
        </rule>
        <rule mark="-" name="neg">
           <alt>
              <literal tmark="-" string="("/>
              <insertion string="-"/>
              <repeat1>
                 <nonterminal name="d"/>
              </repeat1>
              <literal tmark="-" string=")"/>
           </alt>
        </rule>
        <rule mark="-" name="pos">
           <alt>
              <insertion string="+"/>
              <repeat1>
                 <nonterminal name="d"/>
              </repeat1>
           </alt>
        </rule>
        <rule mark="-" name="d">
           <alt>
              <inclusion>
                 <member from="0" to="9"/>
              </inclusion>
           </alt>
        </rule>
    </ixml>

You can experiment with various grammars....
