I have a question..
What should be the output of?
<xsl:template match="/">
<xsl:value-of
select="count(preceding-sibling::node()[1])" />
</xsl:template>
Should it be 0 or 'NaN' .. Or something else?
This is a very easy, straightforward to answer question.
How many preceding-sibling nodes does the document node have?
Exactly zero.
Therefore, the expression in the brackets is the empty node-set.
How many elements does the empty node-set have?
Exactly zero.
Therefore the answer is: 0
