Description

Processing the following XML:

   <testDetailSummary>
      <testReference>Test</testReference>
      <testSummary>
      </testSummary>
      <softwareBuild warning="no">BUILD</softwareBuild>
      <startTime>Wed Jul  8 16:14:55 IST 2015</startTime>
      <endTime>Wed Jul  8 16:16:51 IST 2015</endTime>
   </testDetailSummary>

with the following XSLT:

	<xsl:for-each select="owr/testDetailSummary/*">
						    <xsl:message>Processing test summary</xsl:message>
					
					<li>
						<b>
							<xsl:choose>
							
							<xsl:when test="local-name() = 'testReference'">
							<xsl:message>Processing test ref</xsl:message>
							  <xsl:text>Test Reference: </xsl:text>
							</xsl:when>
							<xsl:when test="local-name() = 'testSummary'">
							<xsl:message>Processing test summary</xsl:message>
							  <xsl:text>Test Summary: </xsl:text>
							</xsl:when>
							<xsl:when test="local-name() = 'startTime'">
							<xsl:message>Processing start time</xsl:message>
							  <xsl:text>Test Start Time: </xsl:text>
							</xsl:when>
							<xsl:when test="local-name() = 'endTime'">
							<xsl:message>Processing end time</xsl:message>
							  <xsl:text>Test End Time: </xsl:text>
							</xsl:when>
							<xsl:when test="local-name() = 'softwareBuild'">
							<xsl:message>Processing software build</xsl:message>
							  <xsl:text>Software Build: </xsl:text>
							</xsl:when>
							<xsl:otherwise>
							  <xsl:value-of select="local-name()"/>
							  <xsl:message>Processing none of testDetailSummary</xsl:message>
							  <xsl:text>:  </xsl:text>
							</xsl:otherwise>
							</xsl:choose>
							
							
						</b>
						<xsl:value-of select="."/>
					</li>
					</xsl:for-each>

With the following output:

Processing test summary
Processing test ref
Processing test summary
Processing test summary

Produces the following exception:
