For some reason, this doesn't seem to work for me.  I
am using saxon as my xslt processor.

I have the following data:

<?xml version="1.0" encoding="iso-8859-1"?>
<info>
        <mytag duration="3 days" />
        <mytag />
        <mytag duration="6 hours" />
        <mytag duration="33 hours" />
        <mytag duration="" />
        <mytag duration="13 hours" />
        <mytag duration="5 days" />
        <mytag duration="" />
        <mytag duration="3 hours" />
        <mytag duration="23 hours" />
</info>


Here is my template:

<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
        <xsl:template match="/">
                <myoutput>
                        <xsl:apply-templates/>
                </myoutput>
        </xsl:template>
        <xsl:template match="mytag">
                <xsl:element name="myelement">
                        <xsl:attribute name="time">
                                <xsl:choose>
                                        <xsl:when 
test="@duration=''">1</xsl:when>
                                        <xsl:when test="@duration">1</xsl:when>
                                        <xsl:otherwise><xsl:value-of
select="@duration"/></xsl:otherwise>
                                </xsl:choose>
                        </xsl:attribute>
                </xsl:element>
        </xsl:template>
</xsl:stylesheet>


And here is the output that I get - note that the
second element has an empty attribute, where it
*should* take the value of 1, given that the second
element in the source data has no duration
attribute...

<?xml version="1.0" encoding="UTF-8"?><myoutput>
        <myelement time="1"/>
        <myelement time=""/>
        <myelement time="1"/>
        <myelement time="1"/>
        <myelement time="1"/>
        <myelement time="1"/>
        <myelement time="1"/>
        <myelement time="1"/>
        <myelement time="1"/>
        <myelement time="1"/>
</myoutput>

Does anyone know what might be wrong here?

thanks heaps guys
