Question

我一直在使用RenderX XEP中的XSL-FO生成简单的PDF，但我对XPath中涉及的功能相对较新。

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格式化对象将这些数据排序到PDF中。所需的格式如下：

所有相同尺寸的门票都在单独的表格中（按字母顺序排列在页面上），每张门票都列出了相关类别和部门。例如：

Desired Output

我已经开始实施Muenchian分组，但是当使用大型XML提取时，错误的类别属于部门之下，而且我还没有能够列出每个类别下面的相关产品。

我可能比较不整洁的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">

我认为问题在于这一行，您尝试迭代某个部门的所有类别

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

问题是变量尺寸包含不同部门的详细信息，而不仅仅是您感兴趣的部门，导致重复。

请尝试此操作，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])]">

Muenchian使用XSL-FO表进行分组
