Select and compare number node

lydiapiglet · December 12th, 2016, 12:21 AM

I would like to target the topicref > topic > topic and change the title with numbering.

I have the following dita map

Code:

<map>
   <chapter>
      <topicref href="ditafile1#topic1">
      <topicref href="ditafile1#topic2">
      <topicref href="ditafile1#topic3">
      and so forth
   </chapter>

   <chapter>
     <topicref href="ditafile2#topic2-1>
     <topicref href="ditafile2#topic2-2>
     and so forth
   </chapter>
</map>

Dita file 1:

Code:

<topic>
  <topic>
      <title>Introduction</title>
  </topic>
  <topic id="topic1>
      <title>Number 1</title>
  </topic>
  <topic id="topic2>
      <title>Number 2</title>
  </topic>
</topic>

Dita file 2

Code:

<topic>
  <topic id="topic2-1">
      <title>Number 2-1</title>
  </topic>
  <topic>
      <title></title>
  </topic>
  <topic id="topic2-2">
      <title>Number 2-2</title>
  </topic>
</topic>

By default,

Code:

<xsl:template match="topic/topic/title">
    <h2>
          <xsl:value-of select="text()"/>
    </h2>
</xsl:template>

If topicref id in href and topic topic id match, change the title, add a numbering 1.1.
Someone suggested this solution, but <xsl:template match="topicref[@href]"> causes some issue that stop all my other html files from generating.

Code:

<xsl:template match="/">
        <xsl:apply-templates select="//topicref"/>
    </xsl:template>

    <xsl:template match="topicref[@href]">
        <xsl:variable name="href" as="xs:string" select="string(@href)"/>
        <xsl:variable name="topicFile" as="xs:string" select="substring-before($href,'#')"/>
        <xsl:variable name="id" as="xs:string" select="substring-after($href,'#')"/>
        <xsl:variable name="levelStr" as="xs:string">
            <xsl:number level="multiple" count="chapter|topicref" format="1.1"/>
        </xsl:variable>
        <xsl:variable name="title" as="text()*">
            <xsl:apply-templates select="document(concat(string(resolve-uri('.', static-base-uri())),$topicFile))//topic[string(@id) eq $id]/title"/>
        </xsl:variable>
        <xsl:value-of select="$levelStr"/>
        <xsl:text> </xsl:text>
        <xsl:value-of select="$title"/>
        <xsl:text>&#x0A;</xsl:text>
    </xsl:template>

Expected output (for the title):
<h2'>1.1 Number 1</h2> // ignore the ' <br/>
<h2'>1.2 Number 2</h2> // ignore the ' <br/>
<h2'>2.1 Number 2-1</h2> // ignore the ' <br/>
<h2'>2.2 Number 2-2</h2> // ignore the ' <br/>

Questions:
How to target for each topicref , the topic topic title change it add numbering infront.
