Dear Experts!! As we all know that XML is the single solution for multiple problems in the field of publishing. We can generate multiple formats from single source and XSL is right choice to develop them. International Digital Publishing Forum (formerly Open eBook Forum) has introduced a new format i.e. ePub. In order to generate TOC, we have certain rules which are shown in the required output. I have started to writing a template with the help of my previous post but it seems that xslt is letting me down in some areas like sequence generation, extracting inner level sections etc. I am clueless as I am already very weak to handling feature like key, collection, regex etc. Any help in this direction is highly appreciable!!!

Rules
ABC (folder)
  a.xml
  b.xml
  n.xml

1. Read the file folder ABC
2. Process each each XML one by one
   A. Process a.xml
      i. Extract article head
      ii. Extract first level head
   B. Process b.xml
      i. Extract article head
      ii. Extract first level head
   N. Process nth.xml
      i. Extract article head
      ii. Extract first level head
3. Generate order sequence

XSL <xsl:variable name="file-collection" select="collection(concat(abc,'abc/?select=*.xml;recurse=yes'))" /> <xsl:template match="/"> <navMap> <navLabel><text>Table of Contents</text></navLabel> <xsl:for-each select="$file-collection"> <navPoint class="chapter" id="" playOrder=""> <navLabel><text><xsl:value-of select="./doc//ti[@t='d']"/></text></navLabel> <content> <xsl:call-template name="source"> <xsl:with-param name="filename"><xsl:value-of select="tokenize(document-uri(.), '/')[last()]"/></xsl:with-param> </xsl:call-template> </content> <navPoint class="section1" id="" playOrder=""> <navLabel><text><xsl:value-of select="./doc//sc1"/></text></navLabel> <content> <xsl:call-template name="source"> <xsl:with-param name="filename"><xsl:value-of select="tokenize(document-uri(.), '/')[last()]"/></xsl:with-param> </xsl:call-template> </content> </navPoint> </navPoint> </xsl:for-each> </navMap> </xsl:template>

OUTPUT REQUIRED <navMap>  <navPoint class="chapter" id="id1" playOrder="1"> <navLabel><text>Article head of A.xml</text></navLabel> <content src="a.htm"/> <navPoint class="section1" id="id2" playOrder="2"> <navLabel><text>Head 1: First level heading of A.xml (first head)</text></navLabel> <content src="a.htm#sec1"/> </navPoint> <navPoint class="section1" id="id3" playOrder="3"> <navLabel><text>Head 1: First level heading of A.xml (second head)</text></navLabel> <content src="a.htm#sec2"/> </navPoint> </navPoint> <navPoint class="chapter" id="id4" playOrder="4"> <navLabel><text>Article head of B.xml</text></navLabel> <content src="B.htm"/> <navPoint class="section1" id="id5" playOrder="5"> <navLabel><text>Head 1: First level heading of B.xml (first head)</text></navLabel> <content src="b.htm#sec1"/> </navPoint> <navPoint class="section1" id="id6" playOrder="6"> <navLabel><text>Head 1: First level heading of A.xml (second head)</text></navLabel> <content src="b.htm#sec2"/> </navPoint> </navPoint> ... </navMap>

Thanks in advance !!!
