Declare a variable named "color". Set its value to the color attribute of the current element. If the current element has no color attribute, the value of "color" will be "green":

<xsl:variable name="color"> <xsl:choose> <xsl:when test="@color"> <xsl:value-of select="@color"/> </xsl:when> <xsl:otherwise>green</xsl:otherwise> </xsl:choose> </xsl:variable> |
