[xsl] Re: Re: AW: AW: global variable and position() once mo

Hi Lizet,

The reason for all problems with this source.xml is its very insufficient
structure.

Therefore, it makes sense to apply a two-step solution, the first step of
which produces a new xml document (actually an RTF, which is converted to a
document using the ext:node-set() extension function).

This new document contains all nodes between two "hr" elements as children
of a "section" element.

The second pass applies the previous solution and produces the final result.
The xsl:key instructions are re-defined to match only text nodes that are
children of a "section" with @name having value of "Claims".

The complete code now is:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
 xmlns:ext="http://exslt.org/common";
  exclude-result-prefixes="ext">

 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 <xsl:strip-space elements="*"/>

 <xsl:key name="kSection"
  match="node()[not(self::hr)]"
  use="generate-id(preceding-sibling::hr[1])"/>

 <xsl:key name="kStart"
  match="section[@name='Claims']/text()
                [preceding-sibling::*[1][self::br]]"
  use="contains(., '.')
     and
       number(substring-before(., '.'))
      =
       number(substring-before(., '.'))"/>

  <xsl:key name="kTrail"
  match="section[@name='Claims']/text()
                [preceding-sibling::*[1][self::br]]"
   use="generate-id(
            preceding-sibling::text()
            [
             contains(., '.')
           and
             number(substring-before(., '.'))
            =
             number(substring-before(., '.'))
            ]
            [1]
                   )"/>

  <xsl:template match="/">
     <xsl:variable name="vrtfStructured">
      <xsl:for-each select="*/hr">
        <section name="{normalize-space(following-sibling::node()[1])}">
         <xsl:copy-of select="key('kSection', generate-id())"/>
        </section>
      </xsl:for-each>
     </xsl:variable>

     <xsl:variable name="vStructured"
select="ext:node-set($vrtfStructured)"/>

     <xsl:for-each select="$vStructured">
      <xsl:for-each select="key('kStart', 'true')">
       <Claim>
        <xsl:copy-of select="normalize-space()"/>
        <xsl:variable name="vLastNumbered" select="position() = last()"/>
        <xsl:for-each select="key('kTrail', generate-id())">
          <xsl:if test="$vLastNumbered or not(position() = last())">
            <xsl:copy-of
             select="concat(substring(.,1,1),
                            normalize-space(substring(.,2))
                            )"/>
          </xsl:if>
        </xsl:for-each>
       </Claim>
      </xsl:for-each>
    </xsl:for-each>
  </xsl:template>
</xsl:stylesheet>


When applied on your source.xml:

<html>
  <hr/>   Claims
  <br/>
  <br/>   I claim:
  <br/>
  <br/>   1. blah blah
  <br/>
  <br/>   more blah blah
  <br/>
  <br/>   2. blah blah blah
  <br/>
  <br/>   more blah blah
  <br/>
  <br/>   3. blah blah
  <br/>
  <br/>   more blah blah
  <br/>
  <br/>   4. blah blah blah
  <br/>
  <br/>   more blah blah
  <br/>
  <hr/>   Description
  <br/>   This is the introduction to the description
  <br/>   1. blah blah
  <br/>
  <br/>   more blah blah
  <br/>
  <br/>   2. blah blah blah

</html>

the wanted result is produced:

<Claim>1. blah blah more blah blah</Claim>
<Claim>2. blah blah blah more blah blah</Claim>
<Claim>3. blah blah more blah blah</Claim>
<Claim>4. blah blah blah more blah blah</Claim>
