I am very new with XSL.
I have one XHTML file and I want merely the <section id="ch01lev2sec01">
element and the first paragraph of that element to become one line that is separated by the UniCode codepoint  
.
The input is:
<section class="bodymatter" id="ch01body">
<section id="ch01lev1sec01">
<header>
<h1 class="title">Assumptions Underlying Content Teaching</h1>
</header>
<p>Most content area teachers assume it is their responsibility to cover their subject matter in a timely, accurate, and effective manner (<a class="biblioref" href="REF.xhtml#ch01bib033">Alvermann & Moore, 1991</a>; <a class="biblioref" href="REF.xhtml#ch01bib034">Moore, 1996</a>). They also assume, for the most part, that textbooks are necessary for teaching and learning content (<a class="biblioref" href="REF.xhtml#ch01bib035">Wade & Moje, 2000</a>). Finally, content area teachers tend to assume that by the time students enter middle and/or high school, they are strategic in their approach to reading and learning (<a class="biblioref" href="REF.xhtml#ch01bib036">Alvermann & Nealy, 2004</a>). These assumptions influence teachers’ instructional decision making, their use of textbooks, and their perceptions of active and independent readers.</p>
<section id="ch01lev2sec01">
<header>
<h1 class="title">Subject Matter</h1>
</header>
<p>The historical</p>
</section>
</section>
</section>
And the required output is:
<section class="bodymatter" id="ch01body">
<section id="ch01lev1sec01">
<header>
<h1 class="title">Assumptions Underlying Content Teaching</h1>
</header>
