Hi Sébastien,
problem is, that tag in XSL should be opened and closed within same parent node.
to fix this you can rewrite XSL in following order:
        <rx:outline>
            <xsl:for-each select="//compte">
                <xsl:variable name="type">
                    <xsl:value-of
                            select="ResourceBundle:getString($libelles, concat('docimgchq.pdf.contenu.libelle.cpt',@serco))"/>
                    <xsl:if test="@serco = '05'">
                        <xsl:value-of select="@serno"/>
                    </xsl:if>
                </xsl:variable>
                <rx:bookmark internal-destination="{$type}">
                    <rx:bookmark-label>
                        <xsl:value-of select="$type"/>
                    </rx:bookmark-label>
                    <xsl:for-each select="cheque[(position() mod 20 = 0) or (position()=1)]">
                        <xsl:variable name="followingGroupId">
                            <xsl:if test="following-sibling::cheque[(count(preceding-sibling::cheque)+1) mod 20 = 0][1]">
                                <xsl:value-of
                                        select="generate-id(following-sibling::cheque[(count(preceding-sibling::cheque)+1) mod 20 = 0][1])"/>
                            </xsl:if>
                        </xsl:variable>
                        <!-- open group of 20 -->
                        <xsl:variable name="cle" select="concat(@datecomptable, @noref)"/>
                        <rx:bookmark internal-destination="{$cle}">
                            <rx:bookmark-label>
                                <xsl:value-of select="@nocheque"/>
                            </rx:bookmark-label>
                        </rx:bookmark>
                        <xsl:for-each select="following-sibling::cheque[not((preceding-sibling::cheque | self::cheque)[generate-id() = $followingGroupId])]">
                            <xsl:variable name="cle1" select="concat(@datecomptable, @noref)"/>
                            <rx:bookmark internal-destination="{$cle1}">
                                <rx:bookmark-label>
                                    <xsl:value-of select="@nocheque"/>
                                </rx:bookmark-label>
                            </rx:bookmark>
                        </xsl:for-each>
                        <!-- close group of 20 -->
                    </xsl:for-each>
                </rx:bookmark>
            </xsl:for-each>
        </rx:outline>

BTW, this source will be more readeble when you rewrite it in apply-templates/mode style.

I know that your example is not correct because your are closing a before closing b.  I am not new to XML syntax.  The problem is that my XML structure is not static.  I am using a loop to generate it.  I did javascript before and it would be possible to open a tag and close it after 20 iterations of the loop and then reopen it and close it again until I am done.

Let me explain my problem a little more.  I have two levels of bookmarks like this:
<group1>
    <item1 />
    <item2 />
    <item3 />
    < .... />
    <item25 />
</group1>
<group2>
    <item26 />
    <item27 />
</group2>

What I would like to do is to add a level of bookmark within group 1 and group 2 which would give me that:
<group1>
    <subgroup1.1>
       <item1 />
       < ... />
       <item20 />
    </subgroup1.1>
    <subgroup1.2>
       <item21 />
       <... />
       <item25>
    </subgroup1.2>
</group1>
<group2>
    <subgroup2.1>
        <item26 />
        <item27 />
    </subgroup2.1>
</group2>

If you look at my code, I am trying to open the "subgroup" bookmark tag before opening the bookmark tag for my "items".  And I try to close the "subgroup" bookmark tag after I have processed 20 items.  I understand that what I am trying to do is not possible because the XML is validated before the processing of the XSL.  If only the result would be validated, everything would be fine.

I would like to know of an alternate way to get what I want.

Thanks for your help!

Sebastien,

 

It is quite obvious what is wrong is that you cannot jump out of a <xsl:if> element.

That is basic XML syntax.

The following is not correct XML:

  <a>

      <b>

  </a>

  </b>

 

Check the W3C xml pages for information on wellformed-ness

Subject: [xep-support] Grouping bookmarks

I am trying to form groups of 20 bookmarks in my document.  I have a document that can have from 1 to 1000 bookmarks and I want them to be grouped by 20.  I tried the "<for-each-group>" tag but xep tells me that I can't use that tag in this part of the xsl.

My rx:outline works fine but when I am trying to place <xsl:if> tags and put <xsl:bookmark> within those if tags, I get an XML validation exception because the bookmark tags are not closed (they are but in an other if).

If I replace "<!-- open group of 20 -->" by "<rx:bookmark ...>" and "<!-- close group of 20 -->" by "</rx:bookmark>" in my code below, I get the validation errors.  What can I do?

<rx:outline>

               <xsl:value-of select="ResourceBundle:getString($libelles, concat('docimgchq.pdf.contenu.libelle.cpt',@serco))"/>
               <xsl:if test="@serco = '05'">
                  <xsl:value-of select="@serno"/>
               </xsl:if>
            </xsl:variable>
            <rx:bookmark internal-destination="{$type}">

            <xsl:for-each select="cheque">
               <xsl:variable name="cle" select="concat(@datecomptable, @noref)"/>
                    <xsl:if test="(count(preceding::cheque)+1) mod 20 = 0">

            </xsl:for-each>
