RE: XSL QUERY

The following is one possible solution:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
  <xsl:output method="xml" indent="yes"/>
  <xsl:template match="/Books">
    <books>
      <xsl:apply-templates select="Author"/>
    </books>
  </xsl:template>

  <xsl:template match="Author">
    <xsl:variable name="auth" select="@name"/>
    <xsl:variable name="spec" select="@Specialist"/>
    <author name="{$auth}" specialist="{$spec}">
      <xsl:apply-templates select="../BookName[contains(@name,$auth) and
@Type = $spec]"/>
    </author>
  </xsl:template>

  <xsl:template match="BookName">
    <bookname name="{@name}" type="{@Type}">

    </bookname>
  </xsl:template>
</xsl:stylesheet>

This generates the following output:

<?xml version="1.0" encoding="utf-8"?>
<books>
   <author name="Author1" specialist="Fiction">
      <bookname name="Author1Book1" type="Fiction"/>
      <bookname name="Author1Book4" type="Fiction"/>
   </author>
   <author name="Author2" specialist="General">
      <bookname name="Author2Book4" type="General"/>
   </author>
</books>
