Re: [xsl] xslt 2 when test multiple conditions

Hi Phil,

The <xsl:value-of> inside your bwhenb conditions do not consider whatever
test might have preceded them; they are simply evaluated as-is when their
bwhenb branch is followed.

In your case, I suggest separating the selection of the record and the
acquisition of the data from that record:

      <!-- get all records, with most preferred response first -->
      <xsl:variable name="sorted-records" as="element(records)*">
        <xsl:perform-sort select="//records">
          <xsl:sort
select="contains(QuestionnaireQuestion/Questionnaire/QuestionnaireIdentifier,
'Safety_MedicalAE')" order="descending"/>
        </xsl:perform-sort>
      </xsl:variable>

      <!-- return first response (or empty value if no match) -->
      <xsl:value-of select="$sorted-records[1]/Response"/>

The sort is a descending Boolean sort, which puts the true() evaluations
first.

Also, you are using <records> for the root element and for your data records.
In my testing, I changed the root element to <root>.

Depending on the granularity of your full data, you might change obtain and
sort on a different element than <records>, adjusting the tests accordingly.

Simple as I can get it
<?xml version="1.0" encoding="UTF-8"?>
<records>
    <Case_Responses>
        <records>
            <QuestionnaireQuestion>
                <DSMapping>Indication</DSMapping_GCC__c>
                <Questionnaire>
                    <QuestionnaireIdentifier>Safety_MedicalAE
Questionnaire</QuestionnaireIdentifier>
                </Questionnaire_GCC__r>
            </QuestionnaireQuestion>
            <Response>rash</Response>
        </records>
        <records>
            <QuestionnaireQuestion>
                <DSMapping>Indication</DSMapping>
                <Questionnaire>
                    <QuestionnaireIdentifier>Safety_Medical_FULL
Questionnaire</QuestionnaireIdentifier>
                </Questionnaire>
            </QuestionnaireQuestion>
            <Response>cough</Response>
        </records>
    </Case_Responses>
</records>

expected output:  rash

Hi Phil,

What is the simplest input XML and expected output XML that describes your
question, without using domain-specific elements (or at least not long
complicated ones)?
