使用第二个xml文档进行xslt转换

标签: xslt-1.0

我有一个xml数据文件,其中包含大量重复字段,每个字段与大约10个唯一设施名称相关联,如下所示:

<Dailyreport>
<msg>
<msgdate>05/27/2015</msgdate>
<facility>North</facility>
<ispass>0</ispass>
</msg>
<msg>
<msgdate>05/27/2015</msgdata>
<facility>South</facility>
<ispass>1</ispass>
</msg>
</Dailyreport>

我有一个XSL样式表版本1.0正在工作,我可以按设施获取出现次数,如下所示:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html"/>
<xsl:template match="/">
<html>
<table style="margin-left:auto;margin-right:auto" rules="all" border="1">

<xsl:if test="Dailyreport//msg[facility='North']">
<tr><td>North Building:</td></tr>
<tr><td>Total:<xsl:value-of select="count(Dailyreport/msg[facility='North'])"/></td></tr>
<tr><td>Pass:<xsl:value-of select="count(Dailyreport/msg[facility='North' and ispass='1'])"/></td></tr>
<tr><td>Fail:<xsl:value-of select="count(DailyELRreport/msg[facility='North' and ispass='0'])"/></td></tr>
<tr><td>-------------------</td></tr>
<tr><td> 
</td></tr>
</xsl:if>
</table>
</html>
</xsl:template>
</xsl:stylesheet>

但是,为了获得所有可能设施的计数,我必须使用每个设施名称重复(xsl:if test)部分。

我想看看我是否可以在第二个xml数据文件中找到设施名称,并使用document()函数通过将它们加载到全局参数中来迭代它们,然后使用调用模板函数来反复调用一个单独的(xsl:if test)部分。并让它使用参数值而不是固定的设施名称......如下所示:

<xsl:if test="Dailyreport//msg[facility=$sender]">

我尝试的一切都失败了。 想知道是否有人可以提供帮助! 谢谢!

鉴于这两个XML文档:

<强> facilities.xml

<facilities>
    <facility code="North">North Building</facility>
    <facility code="South">South Building</facility>
</facilities>

XML(这是由XSLT处理的文档)

<Dailyreport>
   <msg>
    <msgdate>05/27/2015</msgdate>
    <facility>North</facility>
    <ispass>1</ispass>
  </msg>
  <msg>
    <msgdate>05/27/2015</msgdate>
    <facility>North</facility>
    <ispass>1</ispass>
  </msg>
 <msg>
    <msgdate>05/27/2015</msgdate>
    <facility>North</facility>
    <ispass>0</ispass>
  </msg>
  <msg>
    <msgdate>05/27/2015</msgdate>
    <facility>South</facility>
    <ispass>0</ispass>
  </msg>
  <msg>
    <msgdate>05/27/2015</msgdate>
    <facility>South</facility>
    <ispass>0</ispass>
  </msg>
</Dailyreport>

下面的样式表:

XSLT 1.0

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>

<xsl:key name="msg" match="msg" use="facility" />

<xsl:template match="/">
    <xsl:variable name="report" select="." />
    <table border="1">
        <xsl:for-each select="document('facilities.xml')/facilities/facility">
            <tr>
                <th><xsl:value-of select="."/></th>
            </tr>
            <xsl:variable name="code" select="@code" />
            <!-- switch context back to XML document -->
            <xsl:for-each select="$report">
                <xsl:variable name="messages" select="key('msg', $code)" />
                <tr>
                    <td>Total:<xsl:value-of select="count($messages)"/></td>
                </tr>
                <tr>
                    <td>Pass:<xsl:value-of select="count($messages[ispass='1'])"/></td>
                </tr>
                <tr>
                    <td>Fail:<xsl:value-of select="count($messages[ispass='0'])"/></td>
                </tr>
            </xsl:for-each>
        </xsl:for-each>
    </table>
</xsl:template>

</xsl:stylesheet>

将返回:

<?xml version="1.0" encoding="UTF-8"?>
<table border="1">
   <tr>
      <th>North Building</th>
   </tr>
   <tr>
      <td>Total:3</td>
   </tr>
   <tr>
      <td>Pass:2</td>
   </tr>
   <tr>
      <td>Fail:1</td>
   </tr>
   <tr>
      <th>South Building</th>
   </tr>
   <tr>
      <td>Total:2</td>
   </tr>
   <tr>
      <td>Pass:0</td>
   </tr>
   <tr>
      <td>Fail:2</td>
   </tr>
</table>

呈现为:
