I have been having trouble with this grouping problem:

Input:
<book>
<bodymatter>
<story>
<cluster_num>Cluster ONE</cluster_num>
<cluster_head>What Influences a Decision?</cluster_head>
<thinking_skill>Thinking Skill analyzing</thinking_skill>
</story>
<story>
<pagenum>13</pagenum>
</story>
<imggroup>
<img src="DecisionsDecisions3-web-images/Field%20boy%20final_fmt.jpeg" alt="missing image file"/>
<prodnote/></imggroup>
<story>
<pagenum>14</pagenum>
</story>
<story>
<story-title>Playing God</story-title>
<author>Ouida Sebestyen</author>
<p class="initial-paragraph">He was ...</p>
<p>So he wasnt going to get away without saying good-bye after all...</p>
<!--multiple story, image, and page elements edited out-->

    <story>
        <story-title>TLA</story-title>
        <author>Jane McFann</author>
        <p class="initial-paragraph">I trudged down the hallway of ...</p>
        <p ....</p>
        <!--etc-->

<story>
<cluster_num>Cluster TWO</cluster_num>
<cluster_head>Good Decision or Bad Decision?</cluster_head>
<thinking_skill>Thinking Skill evaluating</thinking_skill>
</story>
<story>
<pagenum>51</pagenum>
</story>
<imggroup>
<img src="DecisionsDecisions3-web-images/school%20final_fmt.jpeg" alt="missing image file"/>
<prodnote/></imggroup>
<story>
<pagenum>52</pagenum>
</story>
<story>
<story-title>A Kind of Murder</story-title>
<author>Hugh Pentecost</author>
<p class="initial-paragraph">...</p>
</bodymatter>
</book>

I would like to group each <cluster_num> inside <level1> elements and <story-title> inside <level2> elements
