In XQuery you could do something like this:
<markets>
{
for $market in /markets/market
let $allRunners := $market/runner/@outcome-id
for $market1 in $market/following-sibling::market
let $allRunners1 := $market1/runner/@outcome-id
where deep-equal($allRunners,$allRunners1)
return
<market-ids>
{concat($market/@id, ',', $market1/@id)}
</market-ids>
}
</markets>

(you may have to change the use of fn:deep-equal() if your conditions require different semantics)

In XSLT you can do something like this:
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<xsl:for-each select="markets/market">
<xsl:variable name="marketID">
<xsl:value-of select="@id"/>
</xsl:variable>
<xsl:variable name="runners">
<xsl:for-each select="runner/@outcome-id">
<xsl:value-of select="."/>-</xsl:for-each>
</xsl:variable>
<xsl:for-each select="following-sibling::market">
<xsl:variable name="runners-1">
<xsl:for-each select="runner/@outcome-id">
<xsl:value-of select="."/>-</xsl:for-each>
</xsl:variable>
<xsl:if test="$runners = $runners-1">
<market-ids>
<xsl:value-of select="$marketID"/>,<xsl:value-of select="@id"/></market-ids>
</xsl:if>
</xsl:for-each>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>

(Again, you may have to play with the "$runners = $runners-1" condition)

Hope this helps,
Minollo
