i new when comes xslt. how pick context, 3 words before , after, content tagged element ? have been trying whit string-before , string-after whit no success @ all.

the result should this:

word: end  context: dyb bedrøvelse, men end dybere rolighed, læsde 

we not know whether xslt processor supports xslt 2.0, since wrote answer before realizing that:

the reason version important solution below uses function available in xslt 2.0, namely tokenize(). saying things "selecting 3 words before , after" make sense if tokenize strings want process in fashion. before tokenization, concept of "words" unknown xslt processor.

stylesheet

edit: response comment, have adapted code work several seg elements. of course, introduces other difficulties need deal with.

<?xml version="1.0" encoding="utf-8" ?> <xsl:transform xmlns:xsl="http://www.w3.org/1999/xsl/transform" version="2.0">     <xsl:output method="text"/>      <xsl:template match="seg">       <xsl:text>word: </xsl:text>       <xsl:value-of select="."/>       <xsl:text>&#x0a;context: </xsl:text>        <xsl:variable name="tok-before" select="tokenize(normalize-space(string-join(preceding::text(),'')),' ')"/>       <xsl:variable name="tok-after" select="tokenize(normalize-space(string-join(following::text(),'')),' ')"/>        <xsl:value-of select="subsequence($tok-before,count($tok-before) -2)"/>       <xsl:value-of select="concat(' ',.,' ')"/>       <xsl:value-of select="subsequence($tok-after,1,3)"/>       <xsl:text>&#x0a;</xsl:text>     </xsl:template>      <xsl:template match="text()"/>  </xsl:transform>
