Re: block selection question (XSLT 1.0)

You could frame it as follows:

For each <line> containing "A", output the line and following siblings
having the same number of following siblings containing "B".

<xsl:for-each select="/lines/line[contains(., 'A')]">
	<xsl:variable name="b-count"
select="count(following-sibling::*[contains(., 'B')])"/>
	<xsl:copy-of select="."/>
	<xsl:copy-of
select="following-sibling::*[count(following-sibling::*[contains(.,
'B')]) = $b-count]"/>
</xsl:for-each>
