Subject: Re: [xsl] how do you determine if a property exists? From: David Carlisle <davidc@xxxxxxxxx> Date: Fri, 16 Apr 2004 09:43:28 +0100 |
thanks everyone. The solution I settled on was: <xsl:when test="@duration=''">1</xsl:when> <xsl:when test="not(@duration)">1</xsl:when> This second when clause will never be used, as someone has already commented, if there is no duration attribute, the first test will already be true. You don't need to use xsl:element either as you know the names statically: <xsl:element name="myelement"> <xsl:attribute name="time"> <xsl:choose> <xsl:when test="@duration=''">1</xsl:when> <xsl:when test="not(@duration)">1</xsl:when> <xsl:otherwise><xsl:value-of select="@duration"/></xsl:otherwise> </xsl:choose> </xsl:attribute> </xsl:element> Could rather more consisely be written as <myelement time="1"> <xsl:attribute name="time"> <xsl:value-of select="@duration"/> </xsl:attribute> </myelement> David -- http://www.dcarlisle.demon.co.uk/matthew ________________________________________________________________________ This e-mail has been scanned for all viruses by Star Internet.
