[xsl] Re: sum() over attributes is 0

[Andreas Kemkes <a5sk4s@xxxxxxxxx>]

I'm only subscribed to the digest, so I'm responding to my own message and
hope it will end in the same thread.

Ken:

I'm using Java1.4.2 and according
to the release notes that entails "... xalan-j 2.4.1+ (Xalan version 2.4.1
with controlled 
bug fixes)."

<xsl:comment>
  <xsl:text>count: </xsl:text>
<xsl:value-of select="count(//lc:container[lc:item]/@select)"/>
</xsl:comment>
<!--count: 0-->

but both count(lc:container[lc:item]/@select) and
count(.//lc:container[lc:item]/@select) work.

What would be the issue with
using count(//lc:container[lc:item]/@select)?

Thanks,

Andreas

Subject: sum() over attributes is 0

I'm not having much success using the
sum() function over a node set.

The following two expressions

<xsl:comment>
<xsl:text>sum: </xsl:text>
  <xsl:value-of
select="sum(//lc:container[lc:item]/@select)"/>
</xsl:comment>
<xsl:comment>
<xsl:text>list of select attributes: </xsl:text>
  <xsl:for-each
select="//lc:container[lc:item]">
    <xsl:value-of select="@select"/>
<xsl:text> </xsl:text>
  </xsl:for-each>
</xsl:comment>

result in the
following output:

    <!--sum: 0-->
    <!--list of select attributes: 2 3 1
-->

I'm not clear why the result of sum() is 0.  Are there any other
prerequisites that I'm missing?

Thanks again.
