Remove parent node for the specific child nodes

Using XSLT 1.0, MSXML

I have to transform the following xml file:

<sect>
<p>
  <moveFromRangeStart w:id="22"/>
  <moveFrom id="23">
		<r>
		  <t>want theparagraph to disappear</t>
		</r>
  </moveFrom>
<p>

<p>
  <r>
    <t>leave this</t>
  </r>
  <moveFromRangeStart w:id="24"/>
  <moveFrom id="25">
		<r>
		  <t>more text here</t>
		</r>
  </moveFrom>
<p>

<p>
  <r>
    <t>leave this too</t>
  </r>
  <moveFromRangeStart w:id="29"/>
  <moveFrom id="30">
		<r>
		  <t>more text to be removed here</t>
		</r>
  </moveFrom>
  <r>
    <t>and this</t>
  </r>
<p>
</sect>

into this:

<sect>
<p>
  <r>
    <t>leave this</t>
  </r>  
<p>

<p>
  <r>
    <t>leave this too</t>
  </r>  
  <r>
    <t>and this</t>
  </r>
<p>
</sect>

As you can see, I have to eliminate moveFrom and
moveFromRangeStart nodes and if there are no any other
siblings then remove the parent <p> node.

Thanks in advance
