Subject: [xsl] Choose Test for Emtpy element From: "Karl Stubsjoen" <karl@xxxxxxxxxxxxx> Date: Fri, 14 Mar 2003 10:51:22 -0700 |
Hello, I am performing a CHOOSE | WHERE | OTHERWISE ... the test for this choose is to see whether or not my @AvailableInventory is '' (empty). It doesn't seem to work, but indeed there is no real value in this attribute. I'm thinking it is padded with spaces. So how would I perform my test, but trim all the spaces... or is there another test for "Empty"? Here what I have so far: <xsl:when test="@availableInventory=''"> <xsl:text>-</xsl:text><!-- returning a dash here --> </xsl:when> <xsl:otherwise> <xsl:text>$ </xsl:text> <xsl:value-of select="format-number(@AvailableInventory,'###,###')"/> </xsl:otherwise> </xsl:choose> Thanks!
