我可以在 excel 中显示 10 和 15，但添加部分不起作用。请帮我解决这个问题。
在 XSLT 中，变量是不可变的，不能更改。这意味着您增加 sum 的代码无法按预期工作
<xsl:variable name="sum" select="'0'" />
<xsl:for-each select="plm:PLMXML/plm:ProductView/plm:Occurrence/plm:UserData/plm:UserValue[@title='bl_quantity']">
<xsl:variable name="a" select="@value" />
<xsl:variable name="sum" select="$sum + $a" />
</xsl:for-each>
事实上，这甚至可能被认为是 XSLT 1.0 中的一个错误，因为根据 W3C specification "It is an error if a binding established by an xsl:variable or xsl:param element within a template shadows another binding established by an xsl:variable or xsl:param element also within the template". (It is not an error in XSLT 2.0, but the second sum is local to the xsl:for-each only, and different to the first sum. See http://www.w3.org/TR/xslt20/#scope-of-variables)
无论如何，要解决这个问题，您应该使用 sum 函数。而不是做
<xsl:value-of select="$sum"/>
这样做
<xsl:value-of
select="sum(plm:PLMXML/plm:ProductView/plm:Occurrence/plm:UserData/
plm:UserValue[@title='bl_quantity' and normalize-space(@value)]/@value)"/>
实际上，您可以通过在此处使用变量来简化事情。试试这个 XSLT 片段
<xsl:variable name="bl_quantity" select="plm:PLMXML/plm:ProductView/plm:Occurrence/plm:UserData/plm:UserValue[@title='bl_quantity']" />
<Row>
<xsl:for-each select="$bl_quantity">
<Cell ss:StyleID="s22">
<Data ss:Type="String">
<xsl:value-of select="@value"/>
</Data>
</Cell>
</xsl:for-each>

<xsl:value-of select="sum($bl_quantity[normalize-space(@value)]/@value)"/>
