Although they do have the virtue of giving me my desired output, can the
following sequence of statements be replaced by a more generalized (shorter
and simpler) XPath statement without the repetitive "when" tests shown
below?
<xsl:choose> <xsl:when test="@souvenir-sheet"> <xsl:copy-of select="if (../Location/@souvenir-sheet) then ../Location/@souvenir-sheet else if (../Location/@denomination) then ../Location/@denomination else '0' "/> </xsl:when> <xsl:when test="@minisheet"> <xsl:copy-of select="if(../Location/@minisheet) then ../Location/@minisheet else if(../Location/@denomination) then ../Location/@denomination else '0'"/> </xsl:when> <xsl:when test="@booklet"> <xsl:copy-of select="if(../Location/@booklet) then ../Location/@booklet else if(../Location/@denomination) then ../Location/@denomination else '0'"/> </xsl:when> <xsl:when test="@se-tenant"> <xsl:copy-of select="if (../Location/@se-tenant) then ../Location/@se-tenant else if(../Location/@denomination) then ../Location/@denomination else '0'"/> </xsl:when> <xsl:when test="@coupon"> <xsl:copy-of select=" if (../Location/@coupon) then ../Location/@coupon else if(../Location/@denomination) then ../Location/@denomination else '0'"/> </xsl:when> </xsl:choose> My XPath is very weak. I tried: <xsl:copy-of select="if (../Location[name(@*)=name(@*)]) then ../Location/@* else if(../Location/@denomination) then ../Location/@denomination else '0'"></xsl:copy-of> but it does not restrict the first "then" to returning the value of only locations with an attribute of the same name (as shown in the series of <when> statements). The current context is a <Formats> element with a single attribute (@minisheet, etc.). <Location> elements, if they exist, have a one-to-one relationship with respect to their attribute with their sibling <Formats> elements, i.e, a <Formats @minisheet> element is paired with exactly one <Location @minisheet> sibling, or with no <Location> element at all. In that case substitute value of the single <Locations @denomination> element if it exists, or provide a value of '0' if it does not. If there is not enough info here to correct my faulty try at a simpler XPath statement or to tell me its not going to work no matter what, then I can provide a brief input and desired output selection. Thanks, Mark
