## [xsl] grouping problem

 Subject: [xsl] grouping problem From: Terry Ofner Date: Thu, 15 Apr 2010 18:50:07 -0400
I am attempting to group items in a flat file. Here is a sample of the
input:

<testbody>
<p class="test">A</p>
selection. Then answer the questions that follow.</p>
<p class="head-selectiontitle">Jason and the Golden Fleece</p>
<p class="bodytext-selectionintro">In Greek mythology, ....</p>
<p class="bodytext-numbered">1 King Pelias of Greece, ....</p>

<p class="bodytext-question"><span class="x-qnumber-bold">1</
span>The word invincible in paragraph 14 means</p>
<p class="bodytext-choice"> A full of joy.</p>
<p class="bodytext-choice"> B not happy.</p>
<p class="bodytext-choice"> C having good judgment.</p>
<p class="bodytext-choice"> D unable to be defeated.</p>

<p class="bodytext-question"><span class="x-qnumber-bold">2</
span>This story can be described as an epic tale because</p>
<p class="bodytext-choice"> F someone with magical powers helps
the main character.</p>
<p class="bodytext-choice"> G an ordinary person finds courage. </p>
<p class="bodytext-choice"> H a hero travels to perform a
difficult task for his country. </p>
<p class="bodytext-choice"> J a good character confronts evil
forces.</p>

<p class="bodytext-
questions that follow.</p>
<p class="bodytext-selectionintro">This is an excerpt ....</p>
<p class="oldstyles-normal">ABBY, 13 years old</p>
<p class="oldstyles-normal">LABAN, a slave owner</p>
<p class="oldstyles-normal">TUCKER, his overseer</p>

<p class="bodytext-question"><span class="x-qnumber-bold">11</
span>Why are some .... parentheses?</p>
<p class="bodytext-choice"> A to tell the actors what to do</p>
<p class="bodytext-choice"> B to tell a narrator what to say</p>
<p class="bodytext-choice"> C to tell what sound effects to use</p>
<p class="bodytext-choice"> D to tell the audience what is going
on</p>

</testbody>

Here is the basic grouping 2.0 template (xsl:attribute elements have been removed) in which I am trying to group the @class='bodytext- question and @class=bodytext-choice elements:

<xsl:template match="testbody">
<testbody>
<xsl:for-each-group select="*" group-starting-with="p
[@class=('bodytext-question','bodytext-questionfirst')]">
<xsl:choose>
<xsl:when test="following-sibling::p
[@class='bodytext-choice'][4]">
<xsl:text>&#10;</
xsl:text><xsl:element name="question">

<xsl:apply-templates select="current-group()"/>

</
xsl:element><xsl:text>&#10;</xsl:text>
</xsl:when>
<xsl:otherwise>
<xsl:apply-templates select="current-
group()"/>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each-group>
</testbody>
</xsl:template>

This template works for bodytext-questions that are followed by other
bodytext-questions. But it also groups everything from the start of
<testbody> to the first bodytext-question as well as everything that
follows the last of a series of bodytext-questions.

<testbody>
<question>
<p class="test">A</p>
selection. Then answer the questions that follow.</p>
<p class="head-selectiontitle">Jason and the Golden Fleece</p>
<p class="bodytext-selectionintro">In Greek mythology, ....</p>
<p class="bodytext-numbered">1 King Pelias of Greece, ....</p>
</question>
<question>
<p class="bodytext-question"><span class="x-qnumber-bold">1</
span>The word invincible in paragraph 14 means</p>
<p class="bodytext-choice"> A full of joy.</p>
<p class="bodytext-choice"> B not happy.</p>
<p class="bodytext-choice"> C having good judgment.</p>
<p class="bodytext-choice"> D unable to be defeated.</p>
</question>
<question>
<p class="bodytext-question"><span class="x-qnumber-bold">2</
span>This story can be described as an epic tale because</p>
<p class="bodytext-choice"> F someone with magical powers helps
the main character.</p>
<p class="bodytext-choice"> G an ordinary person finds courage. </p>
<p class="bodytext-choice"> H a hero travels to perform a
difficult task for his country. </p>
<p class="bodytext-choice"> J a good character confronts evil
forces.</p>

<p class="bodytext-
questions that follow.</p>
<p class="bodytext-selectionintro">This is an excerpt ....</p>
<p class="oldstyles-normal">ABBY, 13 years old</p>
<p class="oldstyles-normal">LABAN, a slave owner</p>
<p class="oldstyles-normal">TUCKER, his overseer</p>
</question>
<question>
<p class="bodytext-question"><span class="x-qnumber-bold">11</
span>Why are some .... parentheses?</p>
<p class="bodytext-choice"> A to tell the actors what to do</p>
<p class="bodytext-choice"> B to tell a narrator what to say</p>
<p class="bodytext-choice"> C to tell what sound effects to use</p>
<p class="bodytext-choice"> D to tell the audience what is going
on</p>
</question>

</testbody>

I suspect that I should be using group-adjacent but am I unsure how to
go ahead with such grouping in this case.
