使用XSL-FO表進行Muenchian分組

Question

我一直在使用RenderX XEP中的XSL-FO生成簡單的PDF，但是對於涉及更多XPath的功能我還是比較陌生。

我有一些看起來像這樣的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>

我需要能夠使用XSLT1.0格式設置對象將這些數據排序成PDF表格。 所需的格式如下：

所有大小相同的票證都位於單獨的表中（按字母順序在頁面上排序），每個表都列出了其產品，包含在其相關類別和部門中。 例：

我可以實施Muenchian分組，但是使用大的XML提取時，錯誤的類別屬於部門，並且我無法在每個類別下列出相關產品。

我可能不太整潔的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">

我認為問題出在這條線上，在這里您嘗試遍歷部門的所有類別

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

問題在於變量大小包含不同部門的詳細信息，而不僅僅是您感興趣的部門的詳細信息，從而導致重復。

請嘗試使用此方法，以將其限制為當前部門

<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])]">
