Issue/Introduction
I am using an Apply XSLT Transformation assertion in my policy and I have set the XSLT Messages Prefix in the assertion to "attributeStatement".
When I run the policy, the policy is succeeding but the CVs "${attributeStatement.messages.first}" and "${attributeStatement.messages.last}" are both empty!!
Environment
Release : 10.1
Resolution
These values key in on messages.
Input of X
<?xml version = "1.0"?>
<?xml-stylesheet type = "text/xsl" href = "students.xsl"?>
<class>
<student rollno = "393">
<firstname>FFFFF</firstname>
<lastname>XXXX</lastname>
<nickname>Dinkar</nickname>
<marks>85</marks>
</student>
<student rollno = "493">
<firstname>FFFFFF</firstname>
<lastname>YYYYYY</lastname>
<nickname>Vinni</nickname>
<marks>95</marks>
</student>
<student rollno = "593">
<firstname>FFFFF</firstname>
<lastname>ZZZZZZZ</lastname>
<nickname>Jazz</nickname>
<marks>90</marks>
</student>
</class>
You will note Student 493 Firstname is blank.
XSLT Assertion
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<html>
<body>
<h2>Students</h2>
<table border="1">
<tr bgcolor="#9acd32">
<th>Roll No</th>
<th>First Name</th>
<th>Last Name</th>
<th>Nick Name</th>
<th>Marks</th>
</tr>
<xsl:for-each select="class/student">
<xsl:if test="firstname = ''">
<xsl:message terminate="no">A first name field is empty.
</xsl:message>
</xsl:if>
<tr>
<td><xsl:value-of select="@rollno"/></td>
<td><xsl:value-of select="firstname"/></td>
<td><xsl:value-of select="lastname"/></td>
<td><xsl:value-of select="nickname"/></td>
<td><xsl:value-of select="marks"/></td>
</tr>
</xsl:for-each>
</table>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
I get 1 and only 1 message here about firstname being empty.
Thats because there is 1 defined message in xslt only for that item in an if when the value is empty.
If I add more xsl:message beyond the end if to produce a message like,
<xsl:message terminate="no">A first name field is NOT empty.
</xsl:message>
Then I see additional messages regarding the Not empty firstnames and I see a first and last. in the multivalue context variable.
So the messages (including first and last) are programmed based on your xslt having message attributes
