s gSubject: Transform Name Value pairs into Table Structure.
Author: s g
Date: 23 Feb 2008 04:45 PM
I have an XML dumped out of a webservice call. Basically it just returns a bunch of name value pairs. Based on the Field Names i know which pairs are elements of which table ... but i am not able to figure out if it is possible in XQUERY/XPATH - ultimately i need to produce a report from this information. I hope the Example makes a little more sense. I am a newbie so any help would be greatly appriciated. I hope i have clearly explained the structure...
Basically
Main# is the TableName,
Sub# is the Row denominator
ColName# is the columns and values in the rows...

Please Help.

SouceXML:

<Fields>
<MAIN1_SUB1_COLNAME1>1</MAIN1_SUB1_COLNAME1>
<MAIN1_SUB1_COLNAME2>2</MAIN1_SUB1_COLNAME2>
<MAIN1_SUB1_COLNAME3>3</MAIN1_SUB1_COLNAME3>

<MAIN1_SUB2_COLNAME1>4</MAIN1_SUB2_COLNAME1>
<MAIN1_SUB2_COLNAME2>5</MAIN1_SUB2_COLNAME2>
<MAIN1_SUB2_COLNAME3>6</MAIN1_SUB2_COLNAME3>

<MAIN2_SUB1_COLNAME1>7</MAIN2_SUB1_COLNAME1>
<MAIN2_SUB1_COLNAME2>8</MAIN2_SUB1_COLNAME2>
<MAIN2_SUB1_COLNAME3>9</MAIN2_SUB1_COLNAME3>
</fields>


Target XML:
<fields>
<Main1>
<Sub>
<colname1> 1 </colname1>
<colname2> 2 </colname2>
<colname3> 3 </colname3>
</Sub>
<Sub>
<colname1> 4 </colname1>
<colname2> 5 </colname2>
<colname3> 6 </colname3>
</Sub>
</Main1>
<Main2>
<Sub>
<colname1> 7 </colname1>
<colname2> 8 </colname2>
<colname3> 9 </colname3>
</Sub>
</Main2>
</fields>

Hi,
the most efficient solution would involve using xsl:key, but it could be too hard to understand: try something simpler, like this

<?xml version='1.0'?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="/">
<fields>
<xsl:for-each select="Fields/*">
<xsl:if test="substring(name(),1,5)!=substring(name(preceding-sibling::*[1]),1,5)">
<xsl:variable name="table" select="substring(name(),1,5)"/>
<xsl:element name="{$table}">
<xsl:for-each select=". | following-sibling::*[substring(name(),1,5)=$table]">
<xsl:if test="substring(name(),1,11)!=substring(name(preceding-sibling::*[1]),1,11)">
<xsl:variable name="row" select="substring(name(),7,4)"/>
<xsl:element name="{$row}">
<xsl:for-each select=". | following-sibling::*[substring(name(),1,10)=concat($table,'_', $row)]">
<xsl:element name="{substring(name(),12)}">
<xsl:value-of select="."/>
</xsl:element>
</xsl:for-each>
</xsl:element>
</xsl:if>
</xsl:for-each>
</xsl:element>
</xsl:if>
</xsl:for-each>
</fields>
</xsl:template>

</xsl:stylesheet>

Hope this helps,
Alberto
