You use the xsl:choose dialog box to
test=
xsl:choose
xsl:otherwise
Changes you make here are reflected in the mapper (and the XSLT source), and vice versa.
xsl:when Conditions
List box that displays existing test= attributes of xsl:when conditions).
xsl:when
To add a new xsl:when condition, click the Add button and type a valid test= attribute in the entry field.
Just type the attribute's value. For example, if you want this xsl:when expression, <xsl:when test="books/book/authors/author">, you would just type books/book/authors/author in the entry field. Note the absence of the quotation marks.
<xsl:when test="books/book/authors/author">
Include xsl:otherwise
A check box used to indicate whether or not you want to include the xsl:otherwise element in the xsl:choose instruction. The xsl:otherwise element is included in the xsl:choose instruction by default when you create xsl:choose in the XSLT mapper. If you deselect this check box, the xsl:otherwise port (the square port) is removed from the xsl:choose block (and from the XSLT source).
