java - XSL 多列切换

Question

我有一个 xml，其中列出了客户调用的电话，我需要将其显示在两列中。根据调用次数，列表可以是单页-单栏、单页-双栏或多页-双栏。

我必须使用基本的 apace fop，并且无法访问天线室或类似的库。

当我使用 for-each 时，我可以显示调用，但只能显示在单个列上。我这辈子都无法进入双栏。

我最接近的是下面@Eliot Kimber 的视频，但就是无法回避这样做

我尝试使用列模式，但这又只是在一列中列出所有调用

我的 XML 如下所示。

<CallsMade fromNumber="987654321">

XSL 可以进入多个页面，但下面是单列

<fo:block-container start-indent="0mm" left="5mm" width="48%" span="all">
        <fo:table table-layout="fixed" width="100%" font-size="5pt" text-align="center" display-align="center" span="all">
            <fo:table-column column-width="proportional-column-width(10)"/>
            <fo:table-column column-width="proportional-column-width(15)"/>
            <fo:table-column column-width="proportional-column-width(12)"/>
            <fo:table-column column-width="proportional-column-width(8)"/>
            <fo:table-body font-size="95%" >
                <xsl:for-each select="CallItem">
                    <fo:table-row height="4mm" text-align="center" display-align="center">

                                <xsl:value-of select="DateTime"/>
                            </fo:block>

                        </fo:table-cell>
                    </fo:table-row>

            </fo:table-body>
        </fo:table>
</fo:block-container>

我想知道是否有人可以帮我显示如下列表

Answer 1

看来您确实只需要知道您的 CallItem 是否少于 60 个。如果少于 60，则使表跨越两列，如果不是，则使其跨越一列。正常分页将负责跨列和页面拆分表格。

<xsl:template match="/">
  <fo:root xml:lang="en">
    <fo:layout-master-set>
      <fo:simple-page-master master-name="spm">
        <fo:region-body column-count="2" margin="36pt" />
      </fo:simple-page-master>
    </fo:layout-master-set>
    <fo:page-sequence master-reference="spm">
      <fo:flow flow-name="xsl-region-body">
        <xsl:apply-templates />
      </fo:flow>
    </fo:page-sequence>
  </fo:root>
</xsl:template>

<xsl:template match="CallsMade">
  <fo:block span="all">
    <xsl:value-of select="@fromNumber" />
  </fo:block>
  <fo:block-container>
    <xsl:if test="count(CallItem) &lt; 60">
      <xsl:attribute name="span">all</xsl:attribute>
    </xsl:if>
    <fo:table table-layout="fixed" width="100%" font-size="5pt" text-align="center" display-align="center" span="all">
      <fo:table-column column-width="proportional-column-width(10)"/>
      <fo:table-column column-width="proportional-column-width(15)"/>
      <fo:table-column column-width="proportional-column-width(12)"/>
      <fo:table-column column-width="proportional-column-width(8)"/>
      <fo:table-body font-size="95%" >
        <xsl:apply-templates select="CallItem" />
      </fo:table-body>
    </fo:table>
  </fo:block-container>
</xsl:template>

<xsl:template match="CallItem">
  <fo:table-row height="4mm" text-align="center" display-align="center">
    <fo:table-cell>
      <fo:block>
        <xsl:value-of select="DialledNumber"/>
      </fo:block>
    </fo:table-cell>
    <fo:table-cell>
      <fo:block>
        <xsl:value-of select="DateTime"/>
      </fo:block>
    </fo:table-cell>
    <fo:table-cell>
      <fo:block>
        <xsl:value-of select="Duration"/>
      </fo:block>
    </fo:table-cell>
    <fo:table-cell>
      <fo:block>
        <xsl:value-of select="Cost"/>
      </fo:block>
    </fo:table-cell>
  </fo:table-row>
</xsl:template>
