Question

我是XML和XSL（T）的新手，我被要求采用以下XML文件，其中包含教授的出版物信息及其所有出版物和数据。我被要求计算教授每年的出版物数量，并将结果制成CSV格式。

我知道如何使用XPath来获取DTY_PUB（发布日期年份）标记，并将其添加到CSV中，但我很难在多年内不再重复列中的年份。我来自C / C ++背景，我会用一个简单的hashmap来解决这个问题，我不确定如何在XSLT中解决这个问题。以下是XML文件的缩短版本，下面是我开始使用的XSLT：

</Data>

这是XSLT

<xsl:output method="text" encoding="utf-8"/>
<xsl:variable name="delimiter" select="','"/>
<!-- xmlns:dm is the xmlns attribute in Data.-->


<xsl:key name="Year-Published" match="dm:INTELLCONT" use="dm:DTY_PUB"/>
<xsl:template match="/dm:Data">


 <xsl:text>Year,</xsl:text>
    <xsl:for-each select="dm:Record/dm:INTELLCONT">
        <xsl:value-of select="dm:DTY_PUB"/> <xsl:text>,</xsl:text>
    </xsl:for-each> 

    <!-- output newline -->
    <xsl:text>&#xa;</xsl:text>

</xsl:template>

到目前为止的输出是：

Year,2017,2017,2017,2017,2017,2017,2016,2016,2016,2016,2016,2016,2016,2016,2016

但是，我希望它是：

Year,2017,2016

这需要是版本1，我知道V2有for-each-groups可以相当容易地处理这个问题，而且我无法找出Muenchian分组，如果有人可以解释如何这样做我会这样做永远感激。提前致谢

Answer 1

让它工作，我在正确地将名称插入我的密钥时没有使用单引号：

＆＃13;

<xsl:output method="text" encoding="utf-8"/>
<xsl:variable name="delimiter" select="','"/>
<!-- xmlns:dm is the xmlns attribute in Data.-->


<xsl:key name="Year-Published" match="dm:INTELLCONT" use="dm:DTY_PUB"/>
<xsl:template match="/dm:Data">


  <xsl:text>Year,</xsl:text>
		<xsl:for-each select="dm:Record/dm:INTELLCONT[generate-id()=generate-id(key('Year-Published', dm:DTY_PUB)[1])]">
			<xsl:sort select="(dm:DTY_PUB)" order="ascending"/> 
			<xsl:value-of select="(dm:DTY_PUB)"/> <xsl:text>,</xsl:text>
		</xsl:for-each> 
 <xsl:text>&#xa;</xsl:text>

</xsl:template>
