[xsl] XSLT 2.0 grouping and text nodes and mixed text

[Kenneth Reid Beesley <krbeesley@xxxxxxxxx>]

Relative newbie question:  XSLT 2.0, grouping with text nodes and  
mixed text

I'm trying to convert a non-XML dictionary into XML.  I've got it  
mostly done, but I want to input
elements that currently look like

<examples>
   <hop>source sentence 1</hop>
   translation of source sentence 1
   <hop>source sentence 2</hop>
   translation of source sentence 2
   <hop>source sentence 3</hop>
   a translation can be <emph>mixed</emph> text
</examples>

and transform them into this

<examples>
    <example-pair>
       <hop>source sentence 1</hop>
       <eng>translation of source sentence 1</eng>
   </example-pair>
   <example-pair>
      <hop>source sentence 2</hop>
      <eng>translation of source sentence 2</eng>
   </example-pair>
   <example-pair>
      <hop>source sentence 3</hop>
      <eng>a translation can be <emph>mixed</emph> text</eng>
   </example-pair>
</examples>

i.e. each original <hop> element in <examples> is followed by plain  
text or mixed text,
not containing <hop> or <examples> elements.  I want to group the  
nodes after each
<hop> element and wrap them in <eng>...</eng> tags.  I tried the  
following, and a few
other variations, but the desired <eng> element comes out an empty  
<eng/>


<?xml version="1.0" encoding="UTF-8"?>

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform 
">

	<xsl:output method="xml" indent="yes"/>

	<xsl:template match="examples">
		<examples>
		<xsl:for-each-group select="*" group-starting-with="hop">
			<example-pair>
				<!-- copy the hop element-->
				<xsl:copy-of select="."/>
				<!-- and then surround the mixed text following the hop element
					 with eng tags -->
				<eng>
					<xsl:apply-templates select="current-group() except ."/>
				</eng>
			</example-pair>
		</xsl:for-each-group>
		</examples>
	</xsl:template>

	<!-- default copying of the document -->
	<xsl:template match="@*|node()">
		<xsl:copy>
			<xsl:apply-templates select="@*|node()"/>
		</xsl:copy>
	</xsl:template>

</xsl:stylesheet>

Would some kind guru please tell me how I can do this?

Thanks,

Ken
