Re: Problem with grouping sibling tags

Go to http://xsl.markmail.org/ and search for "group adjacent bullets".

Subject:  Problem with grouping sibling tags

Hey everyone,

I have a problem within an xslt i'm writing that i just can't
figure out how to solve. I think i have to use either some
kind of grouping or work with preceding-sibling or
following-sibling, maybe even both combined together. It has
to be done in xslt version 1.0 which (for as much as i have
read on it) seems to be more complicated on itself as far as
groupings and such go.

Here is a small description together with some samples.

The XML follows a structure like the following ( i have
replaced the original text for 'textcontent' and 'bullet'
otherwise it would get too long a mail):

<?xml version="1.0" encoding="UTF-8"?>
<ArticleContent>
    <Frame Label="BroodTekst">
        <Paragraph Pstyle="Tussenkop">
            <Text Cstyle="[No character style]">textcontent</Text>
            <Text Cstyle="[No character style]"/>
        </Paragraph>
        <Paragraph Pstyle="PlattetekstInitiaal">
            <Text Cstyle="[No character style]">textcontent</Text>
        </Paragraph>
        <Paragraph Pstyle="PlattetekstBullet">
            <Text Cstyle="[No character style]">bullet1</Text>
        </Paragraph>
        <Paragraph Pstyle="PlattetekstBullet">
            <Text Cstyle="[No character style]">bullet2</Text>
        </Paragraph>
        <Paragraph Pstyle="Plattetekst">
            <Text Cstyle="[No character style]">textcontent</Text>
        </Paragraph>
        <Paragraph Pstyle="Plattetekst">
            <Text Cstyle="[No character style]">textcontent</Text>
        </Paragraph>
        <Paragraph Pstyle="PlattetekstBullet">
            <Text Cstyle="[No character style]">bullet3</Text>
        </Paragraph>
    </Frame>
</ArticleContent>

This needs to be converted to another XML file that has the following
structure:

<?xml version="1.0" encoding="utf-8"?>
<section role="broodtekst">
<title role="tussenkop">textcontent</title>
<para role="plattetekstinitiaal">textcontent</para>
<itemizedlist>
	<listitem>
	   <para role="plattetekstbullet">bullet1</para>
	</listitem>
	<listitem>
	   <para role="plattetekstbullet">bullet2</para>
	</listitem>
</itemizedlist>
<para role="plattetekst">textcontent</para>
<para role="plattetekst">textcontent</para>
<itemizedlist>
	<listitem>
	   <para role="plattetekstbullet">bullet3</para>
	</listitem>
</itemizedlist>
</frame>

Now my problem is with the original tags <Paragraph
Pstyle="PlattetekstBullet"> these need to be grouped together
in the new tag <itemizedlist>, but the structure within the
story needs to stay intact. So when another <Paragraph
Pstyle="PlattetekstBullet"> appears that is not preceded or
followed by the same <Paragraph Pstyle="PlattetekstBullet">
tag they need to be grouped as well separately.

I can provide the XSLT i have sofar if needed, but it's a
fairly long one and it might clutter the issue.

Any help would be greatly appreciated and would make my x-mas.

Casper Voortman
