just as you had it (although your posted input only had one book, so the
sequence is of length 1)

select="current-group()/title" is the sequence of title elements so you
could for example do

<xsl:value-of select="current-group()/title" separator=", "/>

to put out a comma separated list of them.

that selects tile attributes of the book elements but you don't have
title attributes, you have title elements.

 <xsl:variable name="selectedBooks" select="/books/book[@title = $titles]"/>

selects all books wose title is in the current list, or at least it
would if the markup was 	<book title="TitleA">
as you posted it with title elements you want to check an element not an
attribute, so

 <xsl:variable name="selectedBooks" select="/books/book[title =
