In 2.0 you simply do:
<xsl:value-of select="(region[(_at_)name='VA'], '0.0')[1]"/>
In 1.0 it's a bit more long-winded:
<xsl:choose>
<xsl:when test="region[(_at_)name='VA']">
<xsl:value-of select="region[(_at_)name='VA']"/>
</xsl:when>
<xsl:otherwise>0.0</xsl:otherwise>
</xsl:choose>

Subject: [xsl] Printing a value if an attribute does not exist
How do you check for the existence of an attribute?
<TIER>
<REGION NAME="CT">89</REGION>
<REGION NAME="MD">135</REGION>
</TIER>
What I want to say is:
If region[(_at_)name="VA"] exists
print value of region[(_at_)name="VA"]
else
print "0.0"
It is also possible that there will be no REGION elements
<TIER>
</TIER>
I would still want to say:
If region[(_at_)name="VA"] exists
print value of region[(_at_)name="VA"]
else
print "0.0"
Thanks
Mike
