Question

我确信之前已经问过这个问题，我只是没有按照正确的标准进行搜索，或者我一直在寻找这个问题太长时间了，看不到木头的树木。

基本上不是XML / XSL转换的新手，它不是我角色的重要部分，我有一个XSL转换，将XML从Microsoft SSRS报告转换为格式化文本文件，以及我正在尝试做什么计算linenumbering以在正确的位置强制分页：

以下是SSRS的XML输出示例：

<?xml version="1.0" encoding="utf-8"?>
<Report  Name="GR_ItemSample.srdl" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="GR_ItemSample.srdl">

    <Item Detail_ItemCode="6407" Detail_Description="SOLU-CORTEF INJ.SOL.250MG ACT-" Detail_UnitOfSale="AOV" Detail_Quantity="1" Detail_UnitPrice="0,00" Detail_Gross="0,00" Detail_Discount1Percentage="0,00" Detail_Discount1Amount="0,00" Detail_Discount2Percentage="0,00" Detail_Discount2Amount="0,00" Detail_Discount3Percentage="0,00" Detail_Discount3Amount="0,00" Detail_Net="0,00" Detail_Lot="TEST123" Detail_VatPercentage="0,0" Detail_MiscDesc2="*** This is a second line description test *******" valueOnlyIdentifier="1" />
</Report>

这是我的示例xsl文件：

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:rpt="GR_ItemSample.srdl">
<xsl:output method="text" omit-xml-declaration="yes" encoding="utf-8" media-type="text/plain"/> 
<xsl:template match="rpt:Report">
    <xsl:variable name="CrLf1" select="'&#13;&#10;'"/>
    <xsl:for-each select="rpt:Item">
        <xsl:value-of select="concat(position(),' - ',@Detail_ItemCode,@Detail_Description,@Detail_UnitOfSale,@Detail_Quantity,@Detail_UnitPrice,@Detail_Gross,@Detail_Discount1Percentage,@Detail_Discount1Amount,@Detail_Discount2Percentage,@Detail_Discount2Amount,@Detail_Discount3Percentage,@Detail_Discount3Amount,@Detail_Net,@Detail_Lot,@Detail_VatPercentage,$CrLf1)"/> 
        <xsl:if test="string-length(@Detail_MiscDesc2) > 0">
            <xsl:value-of select="concat(position(),' - ',@Detail_MiscDesc2,$CrLf1)"/>              
        </xsl:if>
    </xsl:for-each> 
</xsl:template>
</xsl:stylesheet>

现在当我运行转换时，我得到以下输出，这接近我想要的结果：

1 - 6407SOLU-CORTEF INJ.SOL.250MG ACT-AOV10,000,000,000,000,000,000,000,000,00TEST1230,0

我正在使用position（）在我的for-each循环中显示“行号”，现在当我只有一行在文本文件中打印每行时这是完美的，但是添加了一个新的要求已经请求了第二个描述行，第二个描述行出现在与@ Detail_MiscDesc2相同的项目行中，但它必须出现在Text文件输出的下一行，我的xsl有条件地基于字符串长度@ Detail_MiscDesc2，但是我需要知道此时的累计行数，所以我的示例输出实际上应该是这样的：

1 - 6407SOLU-CORTEF INJ.SOL.250MG ACT-AOV10,000,000,000,000,000,000,000,000,00TEST1230,0

8 - *** This is a second line description test *******

我需要这个，因为我还必须计算分页符和页眉和页脚，我知道对于我的文件我总共每页只能有22条细节线。我实际上并不需要打印行号（仅适用于此示例）我只需要知道何时达到22行，这样我就可以处理页脚和分页。我更习惯于程序编程语言，这很容易。我知道我不能使用position（），并且需要使用递归模板，但我无法理解如何做到这一点。任何帮助或指示将不胜感激。我试图尽可能多地提供详细信息而不会太啰嗦（是的，我知道在那里失败了！）但是如果有什么不清楚请告诉我。

Answer 1

您可以打印position()之前的项目，而不是打印先前项目的计数，而不是打印count()，其中包含强制第二行的描述。类似的东西：

count(preceding-sibling::*) + count(preceding-sibling::*[string-length(@Detail_Misc2) &gt; 0])

XSL上的LineNumbering或Incrementing Counter
