I don't think you want to use `index-of` for the check, nor do you need
to use a nested variable and the if, you can write a predicate

 B B B  <xsl:for-each select="//doc[some $a in $abbr satisifies contains(.,
$a)]">

> B B  B B B  B B B  B B B  B B B  B <doc>
> B B  B B B  B B B  B B B  B B B  B B B  B <xsl:attribute
name="no"><xsl:value-of
> select="@no"/></xsl:attribute>
> B B  B B B  B B B  B B B  B B B  B B B  B <xsl:value-of select="$actdoc"/>

If you want to output the found abbreviation then use

 B B B B B B B B B B B B B B B B B B B B B B B B B B B  <xsl:value-of
select="$abbr[contains(current(), .)]"/>
