XSL-FO代码:
我的代码(XSL-FO)包含3列,其中每列包含'A','B','C'的内容
<fo:table-body>
<xfd:table-row-repeat xpath="Root/Data" font-family="Arial Narrow" font-size="10pt" padding-after="0.55cm">
<xsl:if test="Code='A'">
<fo:table-cell>
<fo:block height="12pt">Value
</fo:block>
</fo:table-cell>
<fo:table-cell>
<fo:block height="12pt" border="0.1pt solid black" text-align="center">
<xsl:value-of select="Value" />
</fo:block>
</fo:table-cell>
<fo:table-cell>
<fo:block height="12pt">Points</fo:block>
</fo:table-cell>
</xsl:if>
</xfd:table-row-repeat>
</fo:table-body>
每列的相同代码显示'B'和&amp;的值。 'C' 在表格页脚中,我要得到“A”,“B”,“C”
这些小计<fo:table-body>
<xfd:table-row-repeat xpath="Root/Data" font-family="Arial Narrow" font-size="10pt" padding-after="0.55cm">
<xsl:if test="Code='A'">
<fo:table-cell>
<fo:block height="12pt">SubTotal
</fo:block>
</fo:table-cell>
<fo:table-cell>
<fo:block height="12pt" border="0.1pt solid black" text-align="center">
<--Here Sum of first 15 A's. if the A's or B's or C's exceed by 15, then the table flows to 2nd Page. In that case, 1st Page table-footer shows individual subtotals of first 15 A's, 15 B's and C's. In 2nd Page, the subtotals should contain Subtotal of first 15 A's+ Succeeding A's, in the same way B's and C's -->
</fo:block>
</fo:table-cell>
<fo:table-cell>
<fo:block height="12pt">Points</fo:block>
</fo:table-cell>
</xsl:if>
</xfd:table-row-repeat>
</fo:table-body>
此处XSL-FO代码仅显示一列(For Root / Data / Code ='A'),其他2列('B'和'C')由相同的代码组成。
条件详情:
Condition 1): when Root/Data/Code = 'A' or 'B' or 'C'
i need individual totals of 'A', 'B' and 'C' in Table-Footer individual Column.
Condition 2): inturn if individual count(Root/Data/Code) of 'A', 'B' & 'C' crosses 15. Then Page flows to 2nd Page then Table-Footer in 2nd Page needs to contains subtotal of first 15 A's + the sum of succeeding A's in the same way for B's And C's
即,如果源XML中存在20个A,10个B和25个C.
In 1st Page, Table-Footer
SubtotalI(Value of 15 A's)=
SubtotalII(Value 10 B's)=
SubtotalIII(Value 15 C's)=
In 2nd Page, Table-Footer
SubtotalI(15 A's+ next 5 A's)=
SubtotalII(Value 10 B's)= <!--No Change as count of B's is less than 15 -->
SubtotalIII(15 C's + next 10 C's)=
我正在尝试使用xsl:key通过代码标记进行分组来评估“A”,“B”和“C”的总和。由于我是XSLT的新手,我发现使用xsl:key解决这个逻辑太难了。任何人都可以帮助解决这个逻辑吗?
先谢谢
答案 0 :(得分:0)
您尝试实现的目标存在一些困难。实际上,计算给定点的小计是最简单的。你只需要前面的轴和一个和来计算它:
sum(preceding::Value[../Code = 'A'])
要包含当前值,请使用union运算符,如下所示:
sum(Value[../Code = 'A'] | preceding::Value[../Code = 'A'])
更大的难点是在每个页面上显示不同的表格“页脚”。页眉和页脚会自动在页面上重复,但表格跨越的所有页面的内容都是相同的。我看到的唯一解决方案是自己打破桌面,每次都添加一个不同的表格页脚。
到目前为止,最简单的方法是一次只获取固定数量的数据元素,并将它们显示在单独的表中。您可以在一个for-each中循环遍历A,B和C类型,为每个值分别设置一行。这样,表总是具有相同的行数。您可以尝试使用可以包含的数字来确定一页上适合的数量。
以下代码返回包含前10个Data值的表。 A,B和C值彼此笔直地放置,但如果您愿意,可以分别将它们分别放置在左侧,中间和右侧。在表格的底部添加了三行,包括A,B和C的小计。

您仍然需要一些东西来确定您需要的n个数据项的表数,然后执行一些递归调用以输出所有这些表。希望这足以让你再次前进!
PS:我注意到你正在使用xfd前缀。看起来您正在使用Ecrion的XF Designer。我对它不太熟悉。上面的代码是一个简单的XSLT 1.0解决方案。不确定它是否适用于XF Designer,请告诉我..
