This looks like a sibling recursion problem.

The following seems to work.

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">

       <xsl:output method="xml" indent="yes" />

       <xsl:template match="lines">
	    <result>
                <xsl:apply-templates select="line[contains(., 'A')]"/>
	    </result>
       </xsl:template>

	<xsl:template match="line">
	     <xsl:if test="not(contains(., 'B'))">
		  <xsl:copy-of select="."/>
		  <xsl:apply-templates select="following-sibling::*[1]"/>
	     </xsl:if>
	</xsl:template>

</xsl:stylesheet>
