XSLT嵌套排序/for each

1. 选择节点集。

2. 按日期属性排序。

3. 执行position()以拉取4个节点。

现在,下一部分是我想弄清楚的。在第3步之后,我需要再次按Date属性排序,但这次是按升序排序…现在数据集缩小到4个节点。建议?谢谢你的帮助!!

XSLT:

  <xsl:template name="AdmissionsNewsList">
    <ul class="stories-list">
      <xsl:for-each select="AdmissionsSectionFront/TaxonomyNavigation[@Name='AdmissionsNewsList']/Category/Pages/Page">
        <xsl:sort select="@Date" order="descending" />
              <xsl:if test="position() &lt; 5">

                    <!-- NOW THAT THE NODES HAVE BEEN SELECTED, SORTED, AND POSTION LIMIT SET
                         I NEED TO PERFORM ANOTHER SORT BY DATE (ASCENDING ORDER) HERE ON THE NARROWED DOWN DATA SET -->

                            <li>
                              <xsl:choose>
                                  <xsl:when test="normalize-space(@ThumbnailImage)">
                                      <img alt="{@LocalAlternateText}" src="images/{@ThumbnailImage}" />
                                  </xsl:when>
                                  <xsl:otherwise>
                                      <img alt="{@LocalAlternateText}" src="images/News%20Photos/Default.jpg"/>
                                  </xsl:otherwise>
                              </xsl:choose>
                              <div>
                                <h5>
                                  <xsl:value-of select="@Title"/>
                                </h5>
                                <br/>
                                <xsl:apply-templates select="@Abstract"/>
                                <br/><br/>
                                <a href="{@URL}" class="full-story">
                                  <xsl:apply-templates select="Page[@Name='Link']/@Target"/>Full Story
                                </a>
                              </div>
                            </li>

              </xsl:if> 
      </xsl:for-each>
    </ul>
  </xsl:template>

注意:这必须在xslt1.0中,因为它使用的是msxml4.0解析器。提前谢谢!
