Using the following "dictionary" <?xml version="1.0" encoding="UTF-8"?> <lexikon> <begriff> <synonyme> <synonym>a</synonym> <synonym>b c</synonym> </synonyme> <beschreibung> Tolle Buchstaben. </beschreibung> </begriff> </lexikon> and the following XML input <?xml version="1.0" encoding="UTF-8"?> <text>Da ist ein b c und da ein a</text> the following XSLT 2.0 stylesheet <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="2.0" xmlns:xsl="[URL]http://www.w3.org/1999/XSL/Transform[/URL]"> <xsl:output method="xml" encoding="UTF-8" /> <xsl:variable name="lexwordstring"> <xsl:text>(</xsl:text> <xsl:for-each select="document('test2004121801.xml')/lexikon/begriff/synonyme/*"> <xsl:value-of select="normalize-space(.)"/> <xsl:if test="position() != last()"> <xsl:text>|</xsl:text> </xsl:if> </xsl:for-each> <xsl:text>)</xsl:text> </xsl:variable> <xsl:template match="text()"> <xsl:analyze-string select="." regex="{$lexwordstring}"> <xsl:matching-substring> <a href="" class="lexikon"> <xsl:value-of select="regex-group(1)"/> <xsl:value-of select="document('test2004121801.xml')/lexikon/begriff[synonyme/synonym = regex-group(1)]/beschreibung" /> </a> </xsl:matching-substring> <xsl:non-matching-substring> <xsl:value-of select="."/> </xsl:non-matching-substring> </xsl:analyze-string> </xsl:template> <xsl:template match="*"> <xsl:copy> <xsl:apply-templates /> </xsl:copy> </xsl:template> </xsl:stylesheet> outputs <?xml version="1.0" encoding="UTF-8"?><text>D<a href="" class="lexikon">a Tolle Buchstaben. </a> ist ein <a href="" class="lexikon">b c Tolle Buchstaben. </a> und d<a href="" class="lexikon">a Tolle Buchstaben. </a> ein <a href="" class="lexikon">a Tolle Buchstaben. </a></text> with Saxon 8.1.1, maybe that helps you to find a solution. I realize that more characters are matched than you are looking for (e.g. the 'a' in 'Da'), I have tried to remedy that with using \b in the regular expression but unfortunately it seems the regular expression syntax in XSLT 2.0/XPath 2.0 doesn't know \b (word boundary).
