Words than are not this word

Hello --

I am coming to the opinion that the answer is "you can't do that with an
ixml grammar", but perhaps I'm missing something.

Given an input sentence:

delete the rest of the line and delete line 6 and insert “this; and that;
and the other thing”.

I want to have three results; two that start with delete and one that
starts with insert.

Using
whole = (delBlock|insBlock)+,last,NL.

delBlock = 'delete',space,(word,space)+.
insBlock = 'insert',space,(word,space)+.
last = word.

-space = [Zs],[Zs]*.
word = [L;P;Nd;Sc]+.

-NL = -#A.

I get
<whole ixml:state="ambiguous" xmlns:ixml="http://invisiblexml.org/NS">
  <delBlock>delete <word>the</word> <word>rest</word> <word>of</word>
<word>the</word>
    <word>line</word> <word>and</word> <word>delete</word>
<word>line</word> <word>6</word>
    <word>and</word> </delBlock>
  <insBlock>insert <word>“this;</word> <word>and</word> <word>that;</word>
<word>and</word>
    <word>the</word> <word>other</word> </insBlock>
  <last>
    <word>thing”.</word>
  </last>
</whole>


With the two deletes lumped together.

My reaction is to look for a way to make the matching non-greedy (I haven't
found one) or to define "word" as "anything but this specific string".
(Fairly sure that's impossible in ixml.)

Is there a way to disambiguate this and guarantee that each delete or
insert will start a block?

Thanks!
