How to query all descendant nodes using single xpath expression with multiple conditions

Question

The image shows the nodes in the xml file. I need to find the no of failed testgroups. If any one testcase fails the corresponding testgroup is assumed failed. In the image, failed testgroup count = 2.

The main issue i face here is that in XSLT i cannot have a counter variable in the for-each loop neither can i break out of a for-each loop. I am totally new to functional languages. I dont know how such simple thing are done in XSLT or is it possible to do it in a functional language like XSLT.

The given XSLT manages to show the position of the failed test groups. However what is requied is the count of failed testgroups.

In XSLT, the way to count something is to use the count() function:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

  <xsl:template match="/">
    <html>
      <body>
        <xsl:variable name="allTestGroups" 
                      select="testmodule/testgroup/testgroup" />
        <xsl:variable name="allTestCases" 
                      select="$allTestGroups/testcase" />
        <xsl:variable name="failedTestCases" 
                      select="$allTestCases[verdict/@result = 'fail']" />

        <!-- List names of failed test cases -->           
        <xsl:apply-templates select="$failedTestCases" />

        <xsl:variable name="failedCaseCount" select="count($failedTestCases)" />
        <xsl:variable 
                 name="failedGroupCount" 
                 select="count($allTestGroups[testcase/verdict/@result = 'fail'])" />

        <p>
          <xsl:value-of select="concat('There were ', 
                                       $failedCaseCount, 
                                       ' failed test cases.')"/>
        </p>
        <p>
          <xsl:value-of select="concat('There were ', 
                                       $failedGroupCount, 
                                       ' failed test groups.')"/>
        </p>
      </body>
    </html>
  </xsl:template>

  <xsl:template match="testcase[verdict/@result = 'fail']">
    <p>
      <xsl:value-of select="concat('Test case &quot;', title, '&quot; failed.')"/>
    </p>
  </xsl:template>

</xsl:stylesheet>

When run on your sample input, this produces the output:

<html>
  <body>
    <p>Test case "Test Confirmation(Verify Radio Main - AM source page displayed with 940 kHz frequency tuned)" failed.</p>
    <p>Test case "Test Info(User Action, Connect USB HDD with some audio media )" failed.</p>
    <p>There were 2 failed test cases.</p>
    <p>There were 2 failed test groups.</p>
  </body>
</html>
