XSLT - Best practice for moving specific attributes around - xslt

Question

I was looking for some guidance on how best to approach my issue.
I have an XML document like the following but on a larger scale.
<NewDataSet>
<Table Attri1="Attri1Val" Attri2="Attri2Val" Attri3="Attri3Val" Attri4="Attri4Val" Attri5="Attri5Val" Attri6="Attri6Val" Attri7="Attri7" />
</NewDataSet>
I need to move certain attributes from the Table node, for example Attri2 and Attri5 into elements within the Table node, however I need to leave the rest of the attributes as they are.
What would be the best way to approach this? The data scale is about 3-4 times that shown.
EDIT:
Expected output:
<NewDataSet>
<Table Attri1="Attri1Val" Attri3="Attri3Val" Attri4="Attri4Val" Attri6="Attri6Val" Attri7="Attri7">
<Attri2>Attri2Val</Attri2>
<Attri5>Attri5Val</Attri5>
</Table>
</NewDataSet>
The complexity is not really the issue, more the scale of the data and what is the best way to deal with it.

Answer 1

Use
<xsl:template match="#* | node()">
<xsl:copy>
<xsl:apply-templates select="#* | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="Table">
<xsl:copy>
<xsl:apply-templates select="#*[not(name() = 'Attri2') and not(name() = 'Attri5')]"/>
<xsl:apply-templates select="#Attri2 | #Attri5 | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="Table/#Attri2 | Table/#Attri5">
<xsl:element name="{name()}">
<xsl:value-of select="."/>
</xsl:element>
</xsl:template>
[edit]
The name comparison of the attributes is a bit ugly but will probably do for your sample. What we really need is #* execpt (#Attri2, #Attri5), only that is XPath 2.0. With XPath 1.0 the equivalent is
<xsl:template match="Table">
<xsl:copy>
<xsl:variable name="all-attributes" select="#*"/>
<xsl:variable name="to-be-transformed" select="#Attri2 | #Attri5"/>
<xsl:apply-templates select="$all-attributes[count(. | $to-be-transformed) != count($to-be-transformed)]"/>
<xsl:apply-templates select="$to-be-transformed | node()"/>
</xsl:copy>
</xsl:template>

Answer 2

This generic transformation can handle any set of attributes, with any length, whose names can be specified externally to the transformation:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:param name="pToTransform" select="'|Attri2|Attri5|'"/>
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="Table">
<xsl:copy>
<xsl:apply-templates select=
"#*[not(contains($pToTransform, concat('|',name(),'|')))] | node()"/>
<xsl:apply-templates mode="makeElement"
select="#*[contains($pToTransform, concat('|',name(),'|'))]"/>
</xsl:copy>
</xsl:template>
<xsl:template match="#*" mode="makeElement">
<xsl:element name="{name()}" namespace="{namespace-uri()}">
<xsl:value-of select="."/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
When this transformation is applied to the provided XML document:
<NewDataSet>
<Table Attri1="Attri1Val" Attri2="Attri2Val"
Attri3="Attri3Val" Attri4="Attri4Val"
Attri5="Attri5Val" Attri6="Attri6Val"
Attri7="Attri7" />
</NewDataSet>
the wanted, correct result is produced:
<NewDataSet>
<Table Attri1="Attri1Val" Attri3="Attri3Val" Attri4="Attri4Val" Attri6="Attri6Val" Attri7="Attri7">
<Attri2>Attri2Val</Attri2>
<Attri5>Attri5Val</Attri5>
</Table>
</NewDataSet>
