Re: text indent problem

you don't want to generate a new fo:block on each text node, you just
want a single block for each group of nodes between absatz, so this is a
grouping question, google for
 xslt muenchian grouping
which should lead you to a solution something like this.

<x>
<sec>
Some text, no indent, first paragraph, <b>bold text</b> and <i>italicized</i> text
<absatz />
some other text, with indent
<absatz />
yet other text with <b>bold text</b> and <i>italicized</i> text and <b><i>bold italic</i></b> text
</sec>
<sec>

in addition that the following combination should also be possible:
</sec>
<sec>
Some text, no indent, first paragraph, <b>bold text</b> and <i>italicized</i> text
<absatz />
<i>some</i> other text, with indent
<absatz />
<b>yet</b> other text with <b>bold text</b> and <i>italicized</i> text and <b><i>bold italic</i></b> text
<absatz />
again other text
</sec>
</x>


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

<xsl:key name="a"
	 match="node()" 
	 use="generate-id((preceding-sibling::absatz[1]|.)[1])"
	 />

   <xsl:template match="sec">
     ========= section <xsl:number/> ===
     <xsl:for-each select="node()[1]|absatz">
       <xsl:text>&#10;</xsl:text>
       <block>
	 <xsl:if test="self::absatz">
	   <xsl:attribute name="indent">2em</xsl:attribute>
	 </xsl:if>
	 <xsl:apply-templates select="key('a',generate-id())"/>
       </block>
     </xsl:for-each>
   </xsl:template>

   <xsl:template match="b">
     <bold><xsl:apply-templates/></bold>
   </xsl:template>

   <xsl:template match="italic">
     <italic><xsl:apply-templates/></italic>
   </xsl:template>

   <xsl:template match="absatz"/>

</xsl:stylesheet>


$ saxon indent.xml indent.xsl 
<?xml version="1.0" encoding="utf-8"?>

     ========= section 1 ===
     
<block>
Some text, no indent, first paragraph, </block>
<block indent="2em">
some other text, with indent
</block>
<block indent="2em">
yet other text with <bold>bold text</bold> and italicized text and <bold>bold italic</bold> text
</block>

     ========= section 2 ===
     
<block>

in addition that the following combination should also be possible:
</block>

     ========= section 3 ===
     
<block>
Some text, no indent, first paragraph, </block>
<block indent="2em">
some other text, with indent
</block>
<block indent="2em">
<bold>yet</bold> other text with <bold>bold text</bold> and italicized text and <bold>bold italic</bold> text
</block>
<block indent="2em">
again other text
</block>
