我的预期结果是看到下面的 table 形式...

6mm Black
EnL 1@ 300mm 400mm 1L
EnR 1@ 300mm 400mm 1L
Shelf 1@ 250mm 388mm 1L

6mm White
Back 1@ 300mm 400mm 1L
Bottom 1@ 294mm 388mm 1L
Shelf 2@ 250mm 388mm 1L
Top 1@ 294mm 388mm 1L

但我看到的是：

6mm Black
EnL 1@ 300mm 400mm 1L
EnR 1@ 300mm 400mm 1L
Shelf 1@ 250mm 388mm 1L

6mm White
Back 1@ 300mm 400mm 1L
Bottom 1@ 294mm 388mm 1L
Shelf 2@ 250mm 388mm 1L

问题是为什么它会重复任务，我似乎无法理解 <for-each> 循环比我预期的要多。

(这个转换的原始方法来自这个问题，)

Answer 1

这似乎是 Xalan 处理器中的错误。它由

触发

<xsl:sort select="Comment" />

第 86 行的说明。如果您删除它，重复项将消失。

我应该补充一点，我并没有试图理解您的代码，但在我看来它可以大大简化。也许这也可以防止 bug 出现。

Answer 2

已从内部来源向我提供了解决方法，但它仍然没有改变@Micahael.hor257k 的答案是正确的事实。

如果我们使用；

<xsl:key name="cMaterial" match="Component[DisplayName='Board'][Category='Carcass']" use="concat(generate-id(../../..),'+',Material,'+',Color,'+',DimCut3)" />
<xsl:key name="UcMaterial" match="Component[DisplayName='Board'][Category='Carcass']" use="concat(generate-id(../../..),'+',Material,'+',Color,'+',DimCut3,'+',DimCut2,'+',DimCut1,'+',Comment,'+',Edging,'+',Quantity)" />

然后我们需要做的是使用第一个key的另一个key()在循环中使用，以防止重复发生，就像这样。

<xsl:key name="cMaterial" match="Component[DisplayName='Board'][Category='Carcass']" use="concat(generate-id(../../..),'+',Material,'+',Color,'+',DimCut3)" />
<xsl:key name="cMaterial2" match="Component[DisplayName='Board'][Category='Carcass']" use="concat(generate-id(../../..),'+',Material,'+',Color,'+',DimCut3)" />
    <xsl:key name="UcMaterial" match="Component[DisplayName='Board'][Category='Carcass']" use="concat(generate-id(../../..),'+',Material,'+',Color,'+',DimCut3,'+',DimCut2,'+',DimCut1,'+',Comment,'+',Edging,'+',Quantity)" />

现在在 XSL 中我们可以稍微更改代码以阅读下面的片段；

<xsl:for-each select="VSection/HSection/Component[generate-id()=generate-id(key('cMaterial',concat(generate-id(../../..),'+',Material,'+',Color,'+',DimCut3))[1])]">
                                <xsl:variable name="this" select="." />
                                <fo:table-row>
                                    <!-- 1 --><fo:table-cell number-columns-spanned="4">
                                                        <fo:block>
                                                            <xsl:value-of select="Material" /><xsl:text>: </xsl:text>
                                                            <xsl:value-of select="Color" /><xsl:text>: </xsl:text>
                                                            <xsl:value-of select="DimCut3" />
                                                        </fo:block>
                                                    </fo:table-cell>
                                    <!-- 5 --><fo:table-cell><fo:block></fo:block></fo:table-cell>
                                    <!-- 6 --><fo:table-cell><fo:block></fo:block></fo:table-cell>
                                </fo:table-row>
                                    <xsl:for-each select="key('cMaterial2',concat(generate-id(../../..),'+',$this/Material,'+',$this/Color,'+',$this/DimCut3))">
                                        <xsl:sort select="Comment" />
                                        <xsl:variable name="similar" select="key('UcMaterial',concat(generate-id(../../..),'+',Material,'+',Color,'+',DimCut3,'+',DimCut2,'+',DimCut1,'+',Comment,'+',Edging,'+',Quantity))" />
                                        <xsl:for-each select="../Component[generate-id()=generate-id(key('UcMaterial',concat(generate-id(../../..),'+',Material,'+',Color,'+',DimCut3,'+',DimCut2,'+',DimCut1,'+',Comment,'+',Edging,'+',Quantity))[1])]">
                                            <fo:table-row>
                                                <!-- 1 --><fo:table-cell><fo:block><xsl:value-of select="Comment" /></fo:block></fo:table-cell>
                                                <!-- 2 --><fo:table-cell><fo:block><xsl:value-of select="sum($similar/Quantity)" />@</fo:block></fo:table-cell>
                                                <!-- 3 --><fo:table-cell><fo:block><xsl:value-of select="DimCut1" /></fo:block></fo:table-cell>
                                                <!-- 4 --><fo:table-cell><fo:block><xsl:value-of select="DimCut2" /></fo:block></fo:table-cell>
                                                <!-- 5 --><fo:table-cell><fo:block></fo:block></fo:table-cell>
                                                <!-- 6 --><fo:table-cell><fo:block></fo:block></fo:table-cell>
                                            </fo:table-row>
                                        </xsl:for-each>
                                    </xsl:for-each>
                            </xsl:for-each>

现在我们可以按预期循环并避免由于 Xalan 处理器导致的重复错误。

xsl:for-每个循环都在复制我不期望的东西

xsl:for-each Loop is duplicating things I am not expecting

xml

xslt

xsl-fo
