XML Atom分页

Question

我一直在互联网上努力寻找如何对XML atom提要进行分页的线索，但没有成功。如何在页面上显示用于导航的分页？即第1页和第2页..9

我没有太多使用XML的经验，所以请耐心等待。我见过这个：Pagination in feeds like ATOM and RSS?，但它没有回答我的问题。有什么想法吗伙计们。我真的很感激。

非常感谢各位。

因为你没有展示你尝试过的东西，所以很难准确地弄清楚你想要什么。如果您想要计算给定页面长度的Atom提要中的页面数量，那么可以使用简单的算法：

<xsl:variable name="page-length" select="10"/>

<xsl:template match="atom:feed">
   <xsl:variable name="total" select="count(atom:entry)"/>
   <xsl:choose>
      <xsl:when test="$total eq 0">
         <p>No entry.</p>
      </xsl:when>
      <xsl:otherwise>
         <p>
            <xsl:text>Pages: </xsl:text>
            <xsl:value-of select="(($total - 1) idiv $page-length) + 1"/>
         </p>
      </xsl:otherwise>
   </xsl:choose>
</xsl:template>
