Saving your sample data as `wtf.xml`, here's a quick JSP/JSTL snippet
to illustrate. This static approach is quick'n'dirty and obviously
doesn't give you the flexibility to, say, grab the top /three/ by just
changing a variable. That said,

<c:set var="doc"><c:import url="wtf.xml"/></c:set> <!-- load the data -->
<x:parse xml="${doc}" var="xml"/>                  <!-- parse the data -->

<table rules="all">                                <!-- output the data -->
<tr>
<td><x:out select="$xml/headline/furtherdetails/runner[1]/text()"/></td>
<td><x:out select="$xml/headline/furtherdetails/runner[1]/@id"/></td>
<td><x:out select="$xml/headline/furtherdetails/runner[1]/@handicap"/></td>
<td><x:out select="$xml/headline/furtherdetails/runner[1]/@currentprice"/></td>
<td><x:out select="$xml/headline/furtherdetails/runner[1]/@fractionprice"/></td>
</tr>
<tr>
<td><x:out select="$xml/headline/furtherdetails/runner[2]/text()"/></td>
<td><x:out select="$xml/headline/furtherdetails/runner[2]/@id"/></td>
<td><x:out select="$xml/headline/furtherdetails/runner[2]/@handicap"/></td>
<td><x:out select="$xml/headline/furtherdetails/runner[2]/@currentprice"/></td>
<td><x:out select="$xml/headline/furtherdetails/runner[2]/@fractionprice"/></td>
</table>

<c:set>,<c:import>,<x:parse>,<x:out> are JSP taglibs markup; you'll
have to adapt the XPath statements to your language of choice.

HTH!
