XSL pattern needed for begin/end elements

["Tracy Atteberry" <Tracy.Atteberry@xxxxxxxxxxxx>]

Hi all,

I'm looking for an XSL pattern to solve the problem of going from XML
that has separate begin and end elements to one that does not.

Please, please note that I do not control either the source or target
XML formats.  If I did, this would be much easier.

Source XML snip:

<doc>
  <hyperlink_begin id=3D"111" end=3D"222">
    <locator_url protocol=3D"http" host_name=3D"www.sf.net"/>
  </hyperlink_begin>
  <text_run>Click</text_run>
  <text_run emphasis=3D"bold">here.</text_run>
  <hyperlink_end id=3D"222" begin=3D"111"/>
</doc>

Target XML example:

<cod>
  <HyperLink xlink:href=3D"http://www.sf.net";>
    Click <b>here.</b>
  </HyperLink>
</cod>

In my case I can assume that associated begin and end hyperlink tags
will occur as siblings -- though generally this is not the case and in
fact, this is the reason the begin and end tags are unique elements.

I have a template that /almost/ works so feel free to let me know why it
fails OR suggest a completely different solution.

Current XSL template snip:

<xsl:template match=3D"//hyperlink_begin">
    <xsl:variable name=3D"linkUrl">
        <xsl:value-of select=3D"locator_url/@protocol"/>
        <xsl:text>://</xsl:text>
        <xsl:value-of select=3D"locator_url/@host_name"/>
    </xsl:variable>
    <xsl:variable name=3D"endID" select=3D"@end"/>
    <xsl:element name=3D"HyperLink">
        <xsl:attribute name=3D"xlink:href"><xsl:value-of
select=3D"$linkUrl"/></xsl:attribute>
        <xsl:apply-templates select=3D"(following-sibling::*) except
(following-sibling::hyperlink_end[@id=3D$endID]/following-sibling::*)"/>
    </xsl:element>
</xsl:template>

This produces the correct hyperlink but the template for text_run
elements gets called twice this way -- once inside the hyperlink, then
again as templates continue to be applied.

Any help would be greatly appreciated.  Thanks!
