Re: Building select-clause dynamically with parameter

Probably you think that the following applies the appropriate templates
to ***all*** of the set of the a "chapter" node and its descendents,
the string value of which contains the value of $query?

>     <xsl:template match="/">
>       <xsl:apply-templates 
> select="chapter[contains(descendant-or-self::*,$query)]"/>
>     </xsl:template>

This is wrong. The above code will apply a template only to every
"chapter" node, the text of which contains that of $query -- not to any
descendent of a "chapter", even if the descendent contains the text of
$query.

At first it may seem that a "chapter" will be selected if one of its
descendents contains $query -- this may not be the case. A "chapter"
may be selected even if none of its descendents (including its own
children text nodes) contains $query. This will be the case, when
$query is "made up" by the concatenation of the text of several
descendents.

It seems to me that the code above does not express at all what you
wanted.
