计算特定标记的和

Question

我有一个例子，比如：

<AgentInfo>
      <NumberOfAgent>
         <NUMBER_OF_AGENTS>24</NUMBER_OF_AGENTS>
         <DAY>2018-10-10T00:00:00+01:00</DAY>
         <SKILLSET_NAME>SOA</SKILLSET_NAME>
      </NumberOfAgent>
      <NumberOfAgent>
         <NUMBER_OF_AGENTS>3</NUMBER_OF_AGENTS>
         <DAY>2018-10-10T00:00:00+01:00</DAY>
         <SKILLSET_NAME>C#</SKILLSET_NAME>
      </NumberOfAgent>
      <NumberOfAgent>
         <NUMBER_OF_AGENTS>8</NUMBER_OF_AGENTS>
         <DAY>2018-10-10T00:00:00+01:00</DAY>
         <SKILLSET_NAME>Skillset2</SKILLSET_NAME>
      </NumberOfAgent>
      <NumberOfAgent>
         <NUMBER_OF_AGENTS>1</NUMBER_OF_AGENTS>
         <DAY>2018-10-11T00:00:00+01:00</DAY>
         <SKILLSET_NAME>Uninstalling Windows</SKILLSET_NAME>
      </NumberOfAgent>
   </AgentInfo>

当日期匹配时，我想要计算值的总和(同一天的值)，例如: 2018-10-10天的和将是35。我试了很多但没有运气。

Answer 1

诀窍是先将条目按日分组，然后在组内进行和。尝试以下几点：

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="xml" indent="yes" />
<xsl:template match="AgentInfo">
    <AllUsers>
        <xsl:for-each-group select="NumberOfAgent" group-by="./DAY">
<group>
<count><xsl:value-of select="sum(current-group()/NUMBER_OF_AGENTS)"/></count> 
<day><xsl:value-of select="DAY"/></day>
</group>
        </xsl:for-each-group>
    </AllUsers>
</xsl:template>

</xsl:stylesheet>

Answer 2

?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" encoding="UTF-8" />
<xsl:template match="/">
<xsl:value-of select="sum(/AgentInfo/NumberOfAgent[DAY='2018-10-10T00:00:00+01:00']/NUMBER_OF_AGENTS)"/>
</xsl:template>
</xsl:stylesheet>
