What I didn't mention earlier is that the quote's can't have text
nodes right underneath themselves. All-in-all I have found this to
solve my problem (the last one mentioned anyway, not the one that
started the thread - but inspired by it):
<xsl:template match="p">
<xsl:for-each-group select="./node()" group-starting-with="p | quote
| illustration">
<xsl:choose>
<xsl:when test="(name(current-group()[1])='p') or
(name(current-group()[1])='quote'))">
<xsl:apply-templates select="current-group()[1]"/>
<p>
<xsl:apply-templates select="current-group()[position()>1]"/>
</p>
</xsl:when>
<xsl:otherwise>
<p>
<xsl:apply-templates select="current-group()"/>
</p>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each-group>
</xsl:template>
<xsl:template match="quote">
<quote>
<xsl:for-each-group select="./node()" group-starting-with="p">
<xsl:choose>
<xsl:when test="name(current-group()[1])='p'">
<xsl:apply-templates select="current-group()[1]"/>
<p>
<xsl:apply-templates select="current-group()[position()>1]"/>
</p>
</xsl:when>
<xsl:otherwise>
<p>
<xsl:apply-templates select="current-group()"/>
</p>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each-group>
</quote>
</xsl:template>
Which on the previously stated input gives:
<body>
<!-- case 1 -->
<p>text</p>
<!-- case 2 -->
<quote>
<p>
text
</p>
<p>text</p>
<p>
text
<span>text</span>
</p>
</quote>
<!-- case 3 -->
<quote>
<p>
text
</p>
</quote>
<p/>
<!-- case 4 -->
<p>
text
</p>
<quote>
<p>text</p>
</quote>
<p>
text
<span>text</span>
text
</p>
</body>
Thanks for the help folks.
