I guess you made an error in your input file (besides the typo s/valeur/value/), and there should be only 2 As and only 3 Ds. So you want to walk from words to words starting at the first word, in the document order. For each, either you use its @value or apply each of its suggest, in the document order. For suggest, you want to use its @value and then apply the next word. Doing so, you construct the string from step to step. Where there is no more 'next word', you output the string and you backtrack: (drkm)[4] ~/xslt/tests$ cat spell-check.xml <spellchecker date="Wed Jun 27 17:13:12 CEST 2007"> <word value="a" exist="false"> <suggest value="a1"/> <suggest value="a2"/> </word> <word value="b" exist="true"></word> <word value="c" exist="false"> <suggest value="c1"/> <suggest value="c2"/> <suggest value="c3"/> </word> <word value="d" exist="false"> <suggest value="d1"/> <suggest value="d2"/> <suggest value="d3"/> </word> </spellchecker> (drkm)[5] ~/xslt/tests$ cat spell-check.xsl <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0"> <xsl:output method="text"/> <xsl:template match="spellchecker"> <xsl:apply-templates select="word[1]"/> </xsl:template> <xsl:template match="word"> <xsl:param name="line" select="''"/> <xsl:apply-templates select="suggest"> <xsl:with-param name="line" select="$line"/> </xsl:apply-templates> </xsl:template> <xsl:template match="suggest | word[empty(*)]"> <xsl:param name="line" select="''"/> <xsl:variable name="next-word" select=" ../following-sibling::word[1] | following-sibling::word[1]"/> <xsl:variable name="new-line" select=" concat($line, ' ', @value)"/> <xsl:choose> <xsl:when test="empty($next-word)"> <xsl:value-of select="$new-line"/> <xsl:text> </xsl:text> </xsl:when> <xsl:otherwise> <xsl:apply-templates select="$next-word"> <xsl:with-param name="line" select="$new-line"/> </xsl:apply-templates> </xsl:otherwise> </xsl:choose> </xsl:template> </xsl:stylesheet> (drkm)[6] ~/xslt/tests$ saxon spell-check.xml spell-check.xsl a1 b c1 d1 a1 b c1 d2 a1 b c1 d3 a1 b c2 d1 a1 b c2 d2 a1 b c2 d3 a1 b c3 d1 a1 b c3 d2 a1 b c3 d3 a2 b c1 d1 a2 b c1 d2 a2 b c1 d3 a2 b c2 d1 a2 b c2 d2 a2 b c2 d3 a2 b c3 d1 a2 b c3 d2 a2 b c3 d3 (drkm)[7] ~/xslt/tests$ I think that would help you, if I understood corectly your problem.
