Hello once more,
I downloaded the exsl.zip package to import the exsl.xsl file in the 
stylesheet, but I'm 
currently having problems with it:
The exsl.xsl file is this one:
<?xml version="1.0" encoding="utf-8"?>
<stylesheet xmlns="http://www.w3.org/1999/XSL/Transform"; 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; 
xmlns:exsl="http://exslt.org/exsl"; 
version="1.1" extension-element-prefixes="exsl" 
exsl:doc="http://www.exslt.org/exsl";>
        <import href="node-set/exsl.node-set.xsl"/>
        <import href="object-type/exsl.object-type.xsl"/>
</stylesheet>
and the real paths and names of the used files are these ones:
<import href="functions/node-set/exsl.node-set.xml"/>
<import href="functions/object-type/exsl.object-type.xml"/>
I did that change in the exsl.xsl stylesheet but now I get a different error it 
says 
function not defined in the namespace when I tru to use the node-set function...

thanks again, 
Lizet

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[(_at_)name='Claims']/text()
                [preceding-sibling::*[1][self::br]]"
  use="contains(., '.')
     and
       number(substring-before(., '.'))
      =
       number(substring-before(., '.'))"/>

  <xsl:key name="kTrail"
  match="section[(_at_)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>

Hello Dimitre and all,
The algorithm works very well except for what I mentioned in the previous

email and it

was definetely my fault. I have contiguous text nodes with the description

that have the

same list structure, so the xhtml looks like this:

<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/>
  <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>

So far what I have on the xslt is:
<xsl:key name="kStart"
                     match="text()[preceding-sibling::*[1][self::br]]"
                     use="contains(., '.')
                     and
                     number(substring-before(., '.'))
                     =
                     number(substring-before(., '.'))"/>

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

select="node()[preceding-sibling::text()[starts-with

(normalize-space(.), 'Claims')] and

following::text()[starts-with(normalize-space

(.), 'Description')]] " mode="claims"/>
  </xsl:element>
</xsl:template>

<xsl:template

match="node()[preceding-sibling::text()[starts-with(normalize-space

(.), 'Claims')] and following::text()[starts-with(normalize-space(.),

'Description')]] "

mode="claims">
                   <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:template>


But in the xml output I'm getting the claims alraight except that in the

last claim I

get the fisrt text node of the description included and then starts the

description

list. I know it has to do with:
node()[preceding-sibling::text()[starts-with(normalize-space(.),

'Claims')] and

following::text()[starts-with(normalize-space(.), 'Description')]]
I thought this expression would select the text nodes between 'Claims' and

'Description'

only so I'm still puzzled why it selects nodes after the 'Description'

text node...

Thanks a lot for looking at this,
Lizet

Here's the corrected code (the key definitions are omitted as they are

the

same:

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

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

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

  <xsl:key name="kTrail"
  match="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: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:template>
</xsl:stylesheet>

I believe that two very good books on XSLT are the following:

  "Beginning XSLT" by Jeni Tennison

  "XSLT Programmer's Reference" by Michael Kay.
