I have a union of two node sets which orders the elements in document
order. However, I had expected to see the first set in the union first,
followed by the second set, for example :
<?xml version="1.0" encoding="ISO-8859-1" ?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform" >
<xsl:template match="/">
<dummy>
<xsl:variable name="P" select="//Purchase"/>
<xsl:variable name="Q" select="//Quantity"/>
<xsl:variable name="values" select="$P | $Q"/>
<xsl:for-each select="$values">
<xsl:value-of select="name()"/>
</xsl:for-each>
</dummy>
</xsl:template>
</xsl:stylesheet>
with :
<?xml version="1.0" encoding="ISO-8859-1" ?>
<Root>
<Range Number="1" Total="15.00">
<Purchase>3.00</Purchase>
<Quantity>5</Quantity>
</Range>
<Range Number="2" Total="17.50">
<Purchase>2.50</Purchase>
<Quantity>7</Quantity>
</Range>
<Range Number="3" Total="13.50">
<Purchase>4.50</Purchase>
<Quantity>3</Quantity>
</Range>
</Root>
This displayed :
'PurchaseQuantityPurchaseQuantityPurchaseQuantity'
whereas I had expected to see the 3 Purchase elements followed by the 3
Quantity elements.
Is this normal behaviour for the union operator, I couldn't see anything
in the spec that indicated what ordering should be used ? This was run
on Oracle v2.0.2.8.
