Sorry I had shortened the variable name for the post but clearly not
in the error message which should have read
Description: An empty sequence is not allowed as the value of variable
$averageLineLength

I can get the average like so including the last line
<xsl:variable name="averageLineLength"
select="round(avg($lines/@length))" as="xs:double"/>
I can get the last line length without error
<xsl:variable name="averageLineLength"
select="round(avg($lines[last()]/@length))" as="xs:double"/>
However in the case where my number lines is greater than 2 <xsl:when
test="$numberLines ge 2"> I don't want to include the last line as
part of my count and was trying the following
<xsl:variable name="averageLineLength"
select="round(avg($lines[last()]/preceding-sibling::node()/@length))"
as="xs:double"/>
Which gives me the error:
Description: An empty sequence is not allowed as the value of variable
$averageSpaceNormalizedLineLength
I don't see any code with a variable named
"averageSpaceNormalizedLineLength" in your snippets above so it seems as if
you have not posted the relevant code.
