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>

Subject: [xsl] Flatten XML to load into Oracle DB
Hello.
I have an XML file like this
<?xml version="1.0" encoding="ISO-8859-1"?>
<procind>F
<timedate>20021119-08:26:59
<group>group3
<THEKEY>001001
<FROMDATE>19851231
<type>L
<SOMEGROUP>2530</SOMEGROUP>
<GIND>253010</GIND>
<SECTOR>25</SECTOR>
<SUBIND>25301040</SUBIND>
<TODATE>19860731</TODATE>
</type>
</FROMDATE>
</THEKEY>
<THEKEY>001003
<FROMDATE>19860131
<type>L
<SOMEGROUP>2520</SOMEGROUP>
<GIND>252010</GIND>
<SECTOR>25</SECTOR>
<SUBIND>25201020</SUBIND>
<TODATE>19870130</TODATE>
</type>
</FROMDATE>
<FROMDATE>19870131
<type>L
<SOMEGROUP>2550</SOMEGROUP>
<GIND>255030</GIND>
<SECTOR>25</SECTOR>
<SUBIND>25503020</SUBIND>
<TODATE>19880130</TODATE>
</type>
</FROMDATE>
</THEKEY>
</group>
</timedate>
</procind>
, which I need to load into Oracle DB. It is very easy if I have following
XML:
<ROWSET>
<ROW num="1">
<THEKEY>001001</THEKEY>
<FROMDATE>19851231</FROMDATE>
<type>L</type>
<SOMEGROUP>2530</SOMEGROUP>
<GIND>253010</GIND>
<SECTOR>25</SECTOR>
<SUBIND>25301040</SUBIND>
<TODATE>19860731</TODATE>
</ROW>
<ROW num="2">
<THEKEY>001003</THEKEY>
<FROMDATE>19860131</FROMDATE>
<type>L</type>
<SOMEGROUP>2520</SOMEGROUP>
<GIND>252010</GIND>
<SECTOR>25</SECTOR>
<SUBIND>25201020</SUBIND>
<TODATE>19870130</TODATE>
</ROW>
<ROW num="3">
<THEKEY>001003</THEKEY>
<FROMDATE>19870131</FROMDATE>
<type>L</type>
<SOMEGROUP>2550</SOMEGROUP>
<GIND>255030</GIND>
<SECTOR>25</SECTOR>
<SUBIND>25503020</SUBIND>
<TODATE>19880130</TODATE>
</ROW>
</ROWSET>
With XSL
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0">
<!--xsl:import href="copy.xsl"/-->
<xsl:output method="xml" version="1.0" encoding="UTF-8"
omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="/">
<ROWSET>
<xsl:apply-templates select="//THEKEY"/>
</ROWSET>
</xsl:template>
<xsl:template match="*" mode="flatten">
<xsl:choose>
<xsl:when test="*">
<xsl:element name="ROW">
<xsl:if test="name()='FROMDATE'">
<xsl:attribute name="num"><xsl:number
level="any"/></xsl:attribute>
</xsl:if>
<xsl:apply-templates mode="flatten"/>
</xsl:element>
</xsl:when>
<xsl:otherwise>
<xsl:copy-of select="."/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<xsl:template match="text()" mode="flatten">
<xsl:if test="normalize-space(.) != ''">
<xsl:element name="{name(..)}">
<xsl:value-of select="normalize-space(.)"/>
</xsl:element>
</xsl:if>
</xsl:template>
<xsl:template match="THEKEY">
<xsl:apply-templates mode="flatten"/>
</xsl:template>
</xsl:stylesheet>
I got
<ROWSET>
<THEKEY>001001</THEKEY>
<ROW num="1">
<FROMDATE>19851231</FROMDATE>
<ROW>
<type>I</type>
<SOMEGROUP>2530</SOMEGROUP>
<GIND>253010</GIND>
<SECTOR>25</SECTOR>
<SUBIND>25301040</SUBIND>
<TODATE>19860731</TODATE>
</ROW>
</ROW>
<THEKEY>001003</THEKEY>
<ROW num="2">
<FROMDATE>19860131</FROMDATE>
<ROW>
<type>I</type>
<SOMEGROUP>2520</SOMEGROUP>
<GIND>252010</GIND>
<SECTOR>25</SECTOR>
<SUBIND>25201020</SUBIND>
<TODATE>19870130</TODATE>
</ROW>
</ROW>
<ROW num="3">
<FROMDATE>19870131</FROMDATE>
<ROW>
<type>I</type>
<SOMEGROUP>2550</SOMEGROUP>
<GIND>255030</GIND>
<SECTOR>25</SECTOR>
<SUBIND>25503020</SUBIND>
<TODATE>19880130</TODATE>
</ROW>
</ROW>
</ROWSET>
Can anyone give me a hand with this?
Thank you,
Maxim.
