Hi Mukul
Many thanks for taking the time to covert the stylesheet to pure XSLT
1.0, it is appreciated.
Regards.

Hi Kevin,
A pure XSLT 1.0 solution struck to me(i.e. without
extension functions), and I thought of sharing it with
you.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="xml" indent="yes"/>
<xsl:variable name="filea"
select="document('filea.xml')" />
<xsl:variable name="fileb"
select="document('fileb.xml')" />
<xsl:template match="/">
<supplements>
<!--finding supp-desc tags common to both files
-->
<xsl:for-each select="supplements/supp">
<xsl:variable name="desc-a" select="supp-desc"
/>
<xsl:variable name="price-a" select="supp-price"
/>
<xsl:for-each select="$fileb/supplements/supp">
<xsl:if test="supp-desc = $desc-a">
<supp>
<supp-desc><xsl:value-of
select="supp-desc" /></supp-desc>
<supp-price source="filea"><xsl:value-of
select="$price-a" /></supp-price>
<supp-price source="fileb"><xsl:value-of
select="supp-price" /></supp-price>
</supp>
</xsl:if>
</xsl:for-each>
</xsl:for-each>
<!--finding supp-desc tags existing only in
filea.xml -->
<xsl:for-each select="supplements/supp">
<xsl:variable name="desc-a" select="supp-desc"
/>
<xsl:variable name="price-a" select="supp-price"
/>
<xsl:variable name="temp">
<xsl:for-each
select="$fileb/supplements/supp">
<xsl:if test="supp-desc = $desc-a">
1
</xsl:if>
</xsl:for-each>
</xsl:variable>
<xsl:if test="not(contains($temp, '1'))">
<supp>
<supp-desc><xsl:value-of select="$desc-a"
/></supp-desc>
<supp-price source="filea"><xsl:value-of
select="$price-a" /></supp-price>
<supp-price source="fileb">-</supp-price>
</supp>
</xsl:if>
</xsl:for-each>
<!--finding supp-desc tags existing only in
fileb.xml -->
<xsl:for-each select="$fileb/supplements/supp">
<xsl:variable name="desc-b" select="supp-desc"
/>
<xsl:variable name="price-b" select="supp-price"
/>
<xsl:variable name="temp">
<xsl:for-each

<xsl:if test="supp-desc = $desc-b">
1
</xsl:if>
</xsl:for-each>
</xsl:variable>
<xsl:if test="not(contains($temp, '1'))">
<supp>
<supp-desc><xsl:value-of select="$desc-b"

<supp-price source="filea">-</supp-price>
<supp-price source="fileb"><xsl:value-of
select="$price-b" /></supp-price>
</supp>
</xsl:if>
</xsl:for-each>
</supplements>
</xsl:template>
</xsl:stylesheet>

Hi Mukul
Many thanks for taking the time to supply the
version 1.0 solution. I
changed the extension calls to Saxon (my preference)
and it works fine.
Regards.

Hi Kevin,
Please try this stylesheet. This is a XSLT 1.0
solution and uses a nodeset extension function.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"

<xsl:variable name="filea"
select="document('filea.xml')" />
<xsl:variable name="fileb"
select="document('fileb.xml')" />
<xsl:template match="/">
<supplements>
<!--finding supp-desc tags common to both files
-->
<xsl:for-each select="supplements/supp">
<xsl:variable name="desc-a" select="supp-desc"
/>
<xsl:variable name="price-a" select="supp-price"
/>
<xsl:for-each select="$fileb/supplements/supp">
<xsl:if test="supp-desc = $desc-a">

Hi Everyone
I need to combine two sets of data (File A and
File
B). The structure is as follows (snippet):
FILE A:
<supplements>
<supp>
<supp-desc>Half Board</supp-desc>
<supp-price>£10</supp-price>
</supp>
<supp>
<supp-desc>All Inclusive</supp-desc>
<supp-price>£20</supp-price>
</supp>
<supp>
<supp-desc>Sea View</supp-desc>
<supp-price>£3</supp-price>
</supp>
...
</supplements>
FILE B:
<supplements>
<supp>
<supp-desc>Half Board</supp-desc>
<supp-price>£20</supp-price>
</supp>
<supp>
<supp-desc>All Inclusive</supp-desc>
<supp-price>£40</supp-price>
</supp>
<supp>
<supp-desc>Balcony</supp-desc>
<supp-price>£5</supp-price>
</supp>
...
</supplements>
REQUIRED OUTPUT:
<supplements>
<supp>
<supp-desc>Half Board</supp-desc>
<supp-price source="filea">£10</supp-price>
<supp-price source="fileb">£20</supp-price>
</supp>
<supp>
<supp-desc>All Inclusive</supp-desc>
<supp-price source="filea">£20</supp-price>
<supp-price source="fileb">£40</supp-price>
</supp>
<supp>
<supp-desc>Sea View</supp-desc>
<supp-price source="filea">£3</supp-price>
<supp-price source="fileb">-</supp-price></supp>
<supp>
<supp-desc>Balcony</supp-desc>
<supp-price source="filea">-</supp-price>
<supp-price source="fileb">£5</supp-price></supp>
...
</supplements>
DESCRIPTION:
I need to compare <supp> nodes based on the text
value of <supp-desc>. If the <supp> exists in both
files then the <supp-price> node from File B is
added underneath the <supp-price> node from File A
(a "source" attribute is also added). If the
<supp>
exists in one file but not the other, a
<supp-price>
node with the text value of "-" is added. "Sea
View"
and "Balcony" are examples of <supp> being present
in one file only.
Any suggestions on how best to achieve the desired
result will be greatly appreciated.
