Question

I have several XML elements like this:

  <testcase starttime="2012-09-03 10:41:29" timestamp=" 622.922000">
    <testlogfile file="" />
    <teststep timestamp=" 622.944000" level="0" type="user" ident="1" result="pass">Do something</teststep>
    <teststep timestamp=" 622.965000" level="0" type="user" ident="2" result="pass">Do something</teststep>
    <teststep timestamp=" 622.986000" level="0" type="user" ident="3" result="pass">Do something</teststep>
    <verdict time="2012-09-03 10:41:30" timestamp=" 623.428000" endtime="2012-09-03 10:41:30" endtimestamp=" 623.428000" result="pass" />
    <title>Title goes here</title>
    <ident>TC100_06</ident>
    <description>description goes here</description>
    <extendedinfo type="test case status">Approved</extendedinfo>
    <extendedinfo type="traceability">some requirement</extendedinfo>
    <extendedinfo type="vehicle mode">Hibernate, Parked, Living, Accessory</extendedinfo>
    <extendedinfo type="environment">Station with ATB</extendedinfo>
    <extendedinfo type="variants">veh variants</extendedinfo>
  </testcase>

I would like to make a xsl:variable select query to count testcases by “ident” and “test case status”. I am able to implement 2 separate queries, but I dont know how to join them both:

<xsl:variable name="totalTc" select="count(//testcase[./ident!='text' and ./ident!='obsolete' and ./ident!='rtm' and ./ident!='status overview' and ./ident!='statistics'])"/>
<xsl:variable name="approvedTc" select="count(//extendedinfo[@type='test case status' and text()='Approved'])"/>

I expect joined query should look something like this, but I am unable to query attribute:

<xsl:variable name="totalTc" select="count(//testcase[./ident!='text' and ./ident!='obsolete' and ./ident!='rtm' and ./ident!='status overview' and ./ident!='statistics' and ./extendedinfo=='Approved'])"/>

Answer 1

How about…

<xsl:variable name="totalTc" select="count(
  //testcase[
     ident!='text' and
     ident!='obsolete' and
     ident!='rtm' and
     ident!='status overview' and
     ident!='statistics' and
     extendedinfo[
         @type='test case status' and
         .='Approved']
   ])"/>

Options

Note in XSLT 2.0, you could instead use:

<xsl:variable name="totalTc" select="count(
  //testcase[
     not (ident in ('text','obsolete','rtm','status overview','statistics')) and
     extendedinfo[@type='test case status' and .='Approved']
   ])"/>

Also, instead of an expression of the form …

testcase[ A and B]

… one could instead write….

testcase[A][B]

The former case may be ever so slightly more efficient, but I think personal style should also factor in, in relation to your choice of expression. So for example, one could also put…

<xsl:variable name="totalTc" select="count(//testcase
   [not (ident in ('text','obsolete','rtm','status overview','statistics'))]
   [extendedinfo[@type='test case status'][.='Approved']])"/>
