Xml XSL-总金额

我已经构建了下面的XSL（v2.0）来将CSV文件转换为XML文件。这个钻头很好用！我被卡住的部分是：

汇总所有“收据”元素中“金额”属性中的所有值

然后在“导入\u头”的“记录\u总计”属性中填充总和

运行XSLT后生成的XML如下所示，除了记录之外，没有计算总值（我无法工作的位）

以下是我目前基于包含3行的测试CSV文件的XSL：

    <xsl:stylesheet version="2.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema" >
<xsl:output method="xml" indent="yes"/>

<!-- Parameter used to specify the file location and name of the CSV file -->
<xsl:param name="pathToCSV" select="'file:///c:/csv.csv'" />

<xsl:template match="/">

    <xsl:choose>
    <xsl:when test="unparsed-text-available($pathToCSV)">

        <!-- Read the CSV file and return its contents as a string -->
        <xsl:variable name="csv" select="unparsed-text($pathToCSV)" />

        <!-- Split the csv string into individual rows -->
        <xsl:variable name="rows" select="tokenize($csv, '\r?\n')" /> 

        <!-- Create the root element node and namespace declarations -->        
        <IMPORT_HEADER>

        <!-- Creates the attributes within the root element node -->
        <xsl:attribute name="record_count" select="count($rows)-1"/>
        <xsl:attribute name="record_total" select="'636.13'"/>  

        <!-- Process each row in the CSV file, skip row 1 which contains the column headers -->
        <xsl:for-each select="$rows[position() !=1]">               

            <!-- Split each row into a comma separated list of columns -->
            <xsl:variable name="cols" select="tokenize(., ',')" />

            <!-- Create the child receipt node and populate the attributes -->                          
            <receipt>
                <xsl:attribute name="account_code" select="'12345678'" />
                <xsl:attribute name="amount" select="$cols[12]"/>
            </receipt>      

        </xsl:for-each> 

        </IMPORT_HEADER>

    </xsl:when>
    <xsl:otherwise>
        <xsl:text>Cannot locate : </xsl:text><xsl:value-of select="$pathToCSV" />
    </xsl:otherwise>
    </xsl:choose>   

</xsl:template>

签署了一个XSL新手变得危险了！：）

您需要首先创建

收据

元素并将其存储在变量中，然后您可以对金额求和：

    <xsl:variable name="receipts" as="element(receipt)*">
     <!-- Process each row in the CSV file, skip row 1 which contains the column headers -->
     <xsl:for-each select="$rows[position() !=1]">               

        <!-- Split each row into a comma separated list of columns -->
        <xsl:variable name="cols" select="tokenize(., ',')" />

        <!-- Create the child receipt node and populate the attributes -->                          
        <receipt>
            <xsl:attribute name="account_code" select="'12345678'" />
            <xsl:attribute name="amount" select="$cols[12]"/>
        </receipt>      

     </xsl:for-each> 
    </xsl:variable>

    <IMPORT_HEADER record_count="{count($receipts)}" record_total="sum($receipts/@amount)}">

       <xsl:copy-of select="$receipts"/>  

    </IMPORT_HEADER>

如果您确实想在一个表达式中执行，您可以执行

，但这样做效率不高，因为您会将每行标记两次，因此Martin的优秀答案确实是一种方法。您是一个明星！谢谢你，马丁！那真是太棒了！这让我咯咯地笑了，这个解决方案是多么简单，当你知道怎么做的时候，它是多么简单！安东尼

    <xsl:variable name="receipts" as="element(receipt)*">
     <!-- Process each row in the CSV file, skip row 1 which contains the column headers -->
     <xsl:for-each select="$rows[position() !=1]">               

        <!-- Split each row into a comma separated list of columns -->
        <xsl:variable name="cols" select="tokenize(., ',')" />

        <!-- Create the child receipt node and populate the attributes -->                          
        <receipt>
            <xsl:attribute name="account_code" select="'12345678'" />
