<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template name="test"> <xsl:choose> <xsl:when test="@test='1'"> ... </xsl:when> <xsl:when test="@test='2'"> ... </xsl:when> <xsl:otherwise> ... </xsl:otherwise> </choose> </xsl:template> </xsl:stylesheet>
The test attribute value always expects a boolean result, the value is converted to a boolean as if by a call to the XPath boolean function.
