Description

Simple choose statement (which does not exist in XPath 1.0). Allows less verbose XSL as it can be used instead of xsl:choose. It is also more flexible than xsl:choose because it returns an object (xsl:choose forces the conversion of objects to strings).

Arguments

• cond-1, cond-n: test conditions
• object-1, object-n: objects (string, node-set, etc) to return when their respective condition is true.
• object-other: the object (string, node-set, etc) to return if a respective condition is false. The default value for this parameter is the empty string, '""'.

Returns

• object-i if cond-i is verified and none of cond-1,..., cond-(i-1) is verified.
• object-other if none of the conditions is verified.

Example

    <xsl:value-of select="viv:choose(@score = 1, 'top', @score >  0.5, 'middle', 'bottom')" />
