applying templates to ancestor nodes without reprocess

I've been searching for a week or so and haven't found an answer to this
question, so I thought I'd try posting it. If it's already been
discussed in the past, please direct me to the proper archive.

I'm trying to write a stylesheet for some documents encoded with the TEI
dtd, and am running into a problem. Here is the xml:

<l n="1">There are two Ripenings
    <app>
      <rdg wit="A456 H47"> -</rdg>
      <rdg wit="ATr60a"></rdg>
    </app></l>
    <l n="2">
    <app>
      <rdg wit="A456">one -</rdg>
      <rdg wit="H47">One -</rdg>
      <rdg wit="ATr60a">one</rdg>
    </app> of
    <app>
      <rdg wit="A456">sight -</rdg>
      <rdg wit="H47">Sight - whose Forces</rdg>
      <rdg wit="ATr60a">sight</rdg>
    </app></l>

I want the stylesheet to process each <rdg> element and produce HTML
<div> elements that have corresponding "wit" attributes, but whose
content contains first the content of the xml <l> element (which should
appear in all the HTML <div>s), followed by the specific content of the
current <rdg> element. Here's where I've begun:

<xsl:template match="app" mode="parallel-segmentation">
<xsl:for-each select="rdg">
<div id="line">
<xsl:attribute name="wit"><xsl:value-of select="@wit"/></xsl:attribute>
<xsl:apply-templates/>
</div>
</xsl:for-each>
</xsl:template>

This obviously works for getting just the content of the <rdg> elements.
So here's my question. Before applying the templates to the children of
the <rdg> element (many will have children, though my example doesn't),
I want to process the ancestor <l> element and all of its children
(again, many will have them, though my example doesn't) EXCEPT <app>
(and hence decendant <rdg>) elements. Basically, I want the resultant
HTML to look like this:

<div id="line" wit="A456 H47">There are two Ripenings -</div>
<div id="line" wit="ATr60a">There are two Ripenings</div>
<div id="line" wit="A456">one -</div>
<div id="line" wit="H47">One -</div>
<div id="line" wit="ATr60a">one</div>
<div id="line" wit="A456">of sight -</div>
<div id="line" wit="H47">of Sight - whose Forces</div
<div id="line" wit="ATr60a">of sight</div>

I've tried putting this line into my <app> template:

<xsl:apply-templates select="node()[ancestor::l]" mode="noApps"/>

and then having a new template that looks like this:

<xsl:template name="l" mode="noApps">
<xsl:apply-templates select="node()[not(self::app)]"/>
</xsl:template>

But that, in actuality, re-processes the child <app> elements without
processing any of the other children.

Hope my question makes sense. Sorry the post is so long.
