Hi, I have the following xslt <Secondary> <Body DocumentURI="" IdURI="" NumberOfProvisions="" RestrictStartDate=""> <xsl:for-each select="html:html/html:body/html:div/html:div[@class='page css-gen1']"> <SectionPage> <xsl:value-of select="@id"/> </SectionPage> <Sectionheader> <xsl:value-of select="html:div[1]/html:div/html:span/html:span"/> </Sectionheader> <xsl:when test="html:div[2]/html:div/html:span[@class='css-gen3'] and html:div[2]/html:div[2]/html:span[@class='css-gen5']"> <xsl:call-template name="createStandardHead"/> </xsl:when> </xsl:for-each> Which seems to be fine when running it through the debugger, however when I attempt to run a transformation scenario with the xslt I get the following error: System ID: /media/PENDRIVE/xmlcalabash/xslt/transform_sections.xsl Scenario: STS_Transform XML file: /media/PENDRIVE/xmlcalabash/input/0.1.xhtml XSL file: /media/PENDRIVE/xmlcalabash/xslt/transform_sections.xsl Engine name: Saxon6.5.5 Severity: error Description: xsl:when must be immediately within xsl:choose Start location: 129:0 Is it known that the debugger fails to pick this up?
