Given an XML file that contains a list of Items each having an attribute
Colour with its value,
is it possible to obtain a list of all unique colours of Items.
In this case, you have a number of options:
- use <xsl:key ...>
- use generate-id()
- use an XPath expression like:
<xsl:apply-templates select="Item/Field/Value[not(. = preceding::Value)]"
/>
On big XMLs with a lot of nesting, the first definitely deserves preference.
Please check the FAQ for further help on the usage of the above approaches:
for <xsl:key ...> http://www.dpawson.co.uk/xsl/sect2/N4852.html
for generate-id() http://www.dpawson.co.uk/xsl/sect2/N4416.html
