xml - 使用XSL-FO表进行Muenchian分组

Question

我一直在使用RenderX XEP中的XSL-FO生成简单的PDF，但是对于XPath涉及更多的功能，我还是比较陌生。

我有一些看起来像这样的XML：

<?xml version="1.0" encoding="UTF-8"?>
<report>
    <ticket>
        <size>A</size>
        <department>Dept 1</department>
        <category>Cat 1</category>
        <product>Product 1</product>
    </ticket>
    <ticket>
        <size>A</size>
        <department>Dept 1</department>
        <category>Cat 2</category>
        <product>Product 2</product>
    </ticket>
    <ticket>
        <size>B</size>
        <department>Dept 1</department>
        <category>Cat 2</category>
        <product>Product 3</product>
    </ticket>
    <ticket>
        <size>B</size>
        <department>Dept 1</department>
        <category>Cat 1</category>
        <product>Product 1</product>
    </ticket>
    <ticket>
        <size>C</size>
        <department>Dept 1</department>
        <category>Cat 2</category>
        <product>Product 2</product>
    </ticket>
    <ticket>
        <size>D</size>
        <department>Dept 3</department>
        <category>Cat 1</category>
        <product>Product 4</product>
    </ticket>
    <ticket>
        <size>D</size>
        <department>Dept 1</department>
        <category>Cat 1</category>
        <product>Product 1</product>
    </ticket>
</report>

我需要能够使用XSLT1.0格式设置对象将这些数据排序成PDF表格。所需的格式如下：

所有大小相同的票证都位于单独的表中（在页面中按字母顺序排序），每个表都列出了其产品，包含在其相关类别和部门中。
例：



我可以实施Muenchian分组，但是使用大的XML提取时，错误的类别属于部门，并且我无法在每个类别下列出相关产品。

我可能不太整洁的XSL：

    <xsl:key name="keySize" match="ticket" use="size" />
    <xsl:key name="keyDepartment" match="ticket" use="concat(size, ' ', department)" />
    <xsl:key name="keyCategory" match="ticket" use="concat(size, ' ', department, ' ', category)" />

    <xsl:template match="/report">

我认为问题出在这条线上，在这里您尝试遍历部门的所有类别

<xsl:for-each select="$sizes[generate-id() = generate-id(key('keyCategory', concat(size, ' ', department, ' ', category))[1])]">

问题在于变量大小包含不同部门的详细信息，而不仅仅是您感兴趣的部门的详细信息，从而导致重复。

尝试此操作，以将其限制为当前部门

<xsl:variable name="depts" select="key('keyDepartment', concat(size, ' ', department))" />
<xsl:for-each select="$depts[generate-id() = generate-id(key('keyCategory', concat(size, ' ', department, ' ', category))[1])]">
