Como excluir valores com critérios específicos do arquivo XML no NOTEPAD ++

Question

Eu tenho um arquivo XML muito grande, semelhante a uma árvore, com cerca de 1 GB.

Eu preciso excluir as linhas <Sample> ... </Sample> , incluindo sublines dentro de <Sample> ... </Sample> , que não contêm o valor <segmentation><![CDATA[0.11]]></segmentation> .

Por exemplo, existem linhas com as tags da seguinte forma:

<segmentation><![CDATA[0.11]]></segmentation>
<segmentation><![CDATA[0.25]]></segmentation>
<segmentation><![CDATA[0.61]]></segmentation>

No exemplo abaixo, é possível excluir todas as <Sample> linhas e sub-linhas mantendo apenas <Sample> incluindo sub-linhas com a tag <segmentation><![CDATA[0.11]]></segmentation> ?

Inicial:

  <Sample>
    <title><![CDATA[South Park]]></title>
    <date><![CDATA[Tue, 29 Nov 2016 00:00:00 EST]]></date>
    <referencenumber><![CDATA[20983990]]></referencenumber>
    <segmentation><![CDATA[0.11]]></segmentation>
    <description><![CDATA[Some text goes here]]></description>
  </Sample>
  <Sample>
    <title><![CDATA[South Park]]></title>

    <segmentation><![CDATA[0.25]]></segmentation>
    <description><![CDATA[Some text goes here]]></description>
  </Sample>
  <Sample>

    <date><![CDATA[Tue, 29 Nov 2016 00:00:00 EST]]></date>
    <referencenumber><![CDATA[20983990]]></referencenumber>
    <segmentation><![CDATA[0.61]]></segmentation>
    <description><![CDATA[Some text goes here]]></description>
  </Sample>

Resultado:

  <Sample>
    <title><![CDATA[South Park]]></title>
    <date><![CDATA[Tue, 29 Nov 2016 00:00:00 EST]]></date>
