I have the following XSLT which I need to convert records to a specific XML format:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" indent="yes"/>
<xsl:template match="QUERY">
<xsl:for-each select="REC">
<xsl:call-template name="Questions"/>
</xsl:for-each>
</xsl:template>
<xsl:template name="Questions" match="REC">
<xsl:comment><xsl:value-of select="@PARTREF_"/> | <xsl:value-of select="@PATH_"/></xsl:comment>
<Question>
<xsl:attribute name="PartType"><xsl:value-of select="@PARTREF_"/></xsl:attribute>
<xsl:attribute name="Ref"><xsl:value-of select="@REF_"/></xsl:attribute>
<xsl:attribute name="DataType"><xsl:value-of select="@TYPE_"/></xsl:attribute>
<xsl:attribute name="Text">
<xsl:if test="@AVAILABILITY_">[<xsl:value-of select="@AVAILABILITY_"/>]</xsl:if>
<xsl:value-of select="@TEXT_"/>
</xsl:attribute>
</Question>
</xsl:template>
</xsl:stylesheet>


Running the XSLT on:

<REC N="135" PATH_="Property Owners/Core Premises Cover Sections" PARTREF_="20846" REF_="301969" TEXT_="Hidden construction code qualifier wall 1" AVAILABILITY_="Hidden" TYPE_="SingleSelect" FOLLOWS_="143801"/>
<REC N="136" PATH_="Property Owners/Core Premises Cover Sections" PARTREF_="20846" REF_="301970" TEXT_="Hidden construction code qualifier roof 1" AVAILABILITY_="Hidden" TYPE_="SingleSelect" FOLLOWS_="143801"/>
<REC N="137" PATH_="Property Owners/Core Premises Cover Sections/Buildings" PARTREF_="20847" REF_="143834" TEXT_="Excess (£)" TYPE_="Currency2"/>
<REC N="138" PATH_="Property Owners/Core Premises Cover Sections/Buildings" PARTREF_="20847" REF_="143835" TEXT_="Contingencies" TYPE_="MultiSelect"/>

Will yield:

<!--20846 | Property Owners/Core Premises Cover Sections-->
<Question PartType="20846" Ref="301969" DataType="SingleSelect" Text="[Hidden]Hidden construction code qualifier wall 1"/>
<!--20846 | Property Owners/Core Premises Cover Sections-->
<Question PartType="20846" Ref="301970" DataType="SingleSelect" Text="[Hidden]Hidden construction code qualifier roof 1"/>
<!--20847 | Property Owners/Core Premises Cover Sections/Buildings-->
<Question PartType="20847" Ref="143834" DataType="Currency2" Text="Excess (£)"/>
<!--20847 | Property Owners/Core Premises Cover Sections/Buildings-->
<Question PartType="20847" Ref="143835" DataType="MultiSelect" Text="Contingencies"/>

I would like to get it to yield the following:

<!--20846 | Property Owners/Core Premises Cover Sections-->
<Question PartType="20846" Ref="301969" DataType="SingleSelect" Text="[Hidden]Hidden construction code qualifier wall 1"/>
<Question PartType="20846" Ref="301970" DataType="SingleSelect" Text="[Hidden]Hidden construction code qualifier roof 1"/>
<!--20847 | Property Owners/Core Premises Cover Sections/Buildings-->
<Question PartType="20847" Ref="143834" DataType="Currency2" Text="Excess (£)"/>
<Question PartType="20847" Ref="143835" DataType="MultiSelect" Text="Contingencies"/>

How could I go about doing it? Apologise am new to XSLT!

Any help would greatly be appreciated! :)

Hi David,
you could perform a grouping on the PARTREF_ attribute; have a look at http://www.jenitennison.com/xslt/grouping/ for a list of common algorithms.

Hope this helps,
Alberto

I kind of got it working, but I am now having a problem with mutliple instances showing.

Please see the attached file... I want the <UpdatePart> node only to appear once per REF_.

Output with current XSL:

<!--20742 | Property Owners-->
<Question PartType="20742" Ref="143775" DataType="SingleSelect" Text="Status of entity">
<Actions>
<UpdatePart PartType="20742"/>
</Actions>
<Actions>
<UpdatePart PartType="20742"/>
</Actions>
<Actions>
<UpdatePart PartType="20742"/>
</Actions>
</Question>
<Question PartType="20742" Ref="143776" DataType="Text" Text="Company name"/>
<Question PartType="20742" Ref="143777" DataType="SingleSelect" Text="Title"/>
<Question PartType="20742" Ref="143778" DataType="Text" Text="First name"/>
<Question PartType="20742" Ref="143779" DataType="Text" Text="Surname"/>

Hi David,
your code actually selects three nodes, the ones having TEXT_ equal to "Title", "First name" and "Surname". If what you really want to output is just a single part type for each 'follow' identifier, you should change the key to be

<xsl:key name="following-question-generators" match="*[@PARTREF_]" use="@FOLLOWS_"/>

and the Action template to just select one item from it

<xsl:for-each select="key('following-question-generators', @REF_)[1]">

Hope this helps,
Alberto
