When I encounter the tag I create a new page-sequence but FOP give me an
error because the page-sequence must be in the fo:root and not in a
fo:block. I'am able to change page-sequence, but only if the tag I'm looking
for is at the root. If this tag ("graphic" in my example) is a child of
another tag I didn't find a way to control it.

Exemple:
<?xml version="1.0" encoding="UTF-8"?>
<wp>
  <para>para 1
    <para>para 1.1</para>
  </para>
  <para>para 2</para>
  <para>para 3</para>
  <graphic>graphic 1</graphic>
  <para>para 4</para>
  <graphic>graphic 2</graphic>
  <graphic>graphic 3</graphic>
  <para>para 5
    <para>para 5.1
      <graphic>graphic 4</graphic>
    </para>
  </para>
</wp>

Can anyone help me?

You need to look into grouping techniques in order to
sort of "pull the special tag to the top level". It's
somewhat hairrising though.

Hi

Some friendly advice to start:
Would you be so kind the next time, to post in plain-text? Not a problem for
me specifically, but some would find it a reason to ignore your question if
you don't... Just imagine for a moment what all that HTML looks like in
plain text view.

Now as to your question:

I think you're going to need three XSL templates for this:
(more of a Mulberry-question, come to think of it)

- one for the plain <para .../> elements (sans graphiques ;) )
- one for the <graphic .../> elements that are children of the root
- one to handle <graphic /> elements with <para .../> ancestors

Example stylesheet:

<?xml version="1.0" encoding="iso-8859-1" ?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" />

<xsl:template match="wp">
  <foroot>
    <xsl:apply-templates select="para[not(descendant::graphic)]
                                 | //graphic" />
  </foroot>
</xsl:template>

<xsl:template match="para[not(descendant::graphic)]">
  <xsl:choose>
  <xsl:when test="parent::wp">
    <fopageseq ref="a">
      <foblock>
        <xsl:apply-templates />
      </foblock>
    </fopageseq>
  </xsl:when>
  <xsl:otherwise>
    <foblock>
      <xsl:apply-templates />
    </foblock>
  </xsl:otherwise>
  </xsl:choose>
</xsl:template>

<xsl:template match="graphic[parent::wp]">
  <fopageseq ref="b">
    <foextgraph src="{.}" />
  </fopageseq>
</xsl:template>

<xsl:template match="graphic[ancestor::para]">
  <fopageseq ref="a">
    <xsl:for-each select="ancestor::para">
      <xsl:sort select="position()" order="ascending" />
        <foblock>
          <xsl:value-of select="text()" />
        </foblock>
    </xsl:for-each>
  </fopageseq>
  <fopageseq ref="b">
    <foextgraph src="{.}" />
  </fopageseq>

</xsl:template>

</xsl:stylesheet>

Modify this to use real fo's, and use it to transform your example XML. Only
case not handled by the above template is: a <para> that would be following
'graphic 4' in your example, but would still be a child of the 'para 5'
node... Just to give you an idea.


Cheers,

Andreas
