Mike Kay would accuse you of guessing at syntax... The syntax of
xsl:choose is:
<xsl:choose>
<xsl:when test="...">
...
</xsl:when>
... more xsl:when elements ...
<xsl:otherwise>
...
</xsl:otherwise>
</xsl:choose>
If you want to check whether the contents element has a string value
then use the test "string(contents)". So your xsl:choose should be:
<xsl:choose>
<xsl:when test="string(contents)">
<xsl:value-of select="contents" />
</xsl:when>
<xsl:otherwise>default.jpg</xsl:otherwise>
</xsl:choose>
Cheers,
Jeni
