我想编写一个XSLT来将XML文档转换为XML-FO文档，以生成PDF。
此图片显示current Output
所以我的表有3列。在前4行中，第二列和第三列合并。
我的XML文档如下所示：
<WS-Standards>
<tags>
<tag category = "parameters" > <!-- WS_Beer_Type -->
<tag_name>WS_Beer_TypeX</tag_name> <!-- browsename -->
<tag_number>30004</tag_number>
<datatype>Unsigned32</datatype>
<accessrights>RW</accessrights>
<names>
<name language="DE">Biersorte</name>
<name language="EN">Beer Type</name>
</names>
</tag>
</tags>
</WS-Standards>
我当前的XSLT文档：

我的问题是关于不同语言的名称元素。
因此，names元素表中的第一行如下所示：
-----------------------------
|Name | DE | Biersorte |
-----------------------------
但我错过了第二行：
-----------------------------
| | EN | beer type |
-----------------------------
xsl我做错了什么：choose-＆gt; when-＆gt;否则函数？
我很乐意提示。
答案 0 :(得分：1)
相关代码位于匹配names的模板中，但XSLT中只有一个这样的元素，因此只会调用一次。
此上下文中的表达式number(./name/position()) = 1只是询问＆＃34;对于此names元素，位置1和＃34;中是否有name元素，这是真的，并且所以xsl:when被执行了。
您的代码确实需要位于选中name的块中。试试这个XSLT（它也删除了代码重复）。
<xsl:template match="names">
<xsl:for-each select="name">
<fo:table-row>
<fo:table-cell column-number="1" border="1pt solid black">
<fo:block>
<xsl:if test="position() = 1">Name</xsl:if>
</fo:block>
</fo:table-cell>
<fo:table-cell column-number="2" border="1pt solid black">
<fo:block>
<xsl:value-of select="@language"/>
</fo:block>
</fo:table-cell>
<fo:table-cell column-number="3" border="1pt solid black">
<fo:block>
<xsl:value-of select="."/>
</fo:block>
</fo:table-cell>
</fo:table-row>
</xsl:for-each>
</xsl:template>
