I don't know whether this is too simple, but I think this could work (not tested)

<xsl:template match="answer" name="answer">
  <xsl:if test="@eval='correct'">
    <xsl:value-of select="position()"/>. <xsl:value-of select="@eval"/>
  </xsl:if>
</xsl:template>

This outputs the position of the answers which are correct like this:
3. correct

You can call it like this
<xsl:apply-templates select="//answer"/> 
from your main template.
