Hi Max, Unless I'm missing a subtle point here, the flattening can be much simpler than your approach. Something like this would work: <xsl:template match="procind | timedate | group | THEKEY"> <xsl:apply-templates select="*" /> </xsl:template> <xsl:template match="FROMDATE"> <ROW num="{count(preceding::FROMDATE)+1}"> <xsl:for-each select="ancestor::THEKEY"> <THEKEY> <xsl:value-of select="normalize-space(text()[1])" /> </THEKEY> </xsl:for-each> <FROMDATE> <xsl:value-of select="normalize-space(text()[1])" /> </FROMDATE> <xsl:for-each select="descendant::*"> <xsl:element name="{local-name()}"> <xsl:value-of select="normalize-space(text()[1])" /> </xsl:element> </xsl:for-each> </ROW> </xsl:template> Bryan -----Original Message----- From: Syrnev, Max [mailto:Max_Syrnev@xxxxxxxxxxxxxxxxxxxx] Sent: Tuesday, February 10, 2004 10:10 AM To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx Subject: [xsl] Flatten XML to load into Oracle DB Hello.
