Hi Ian,

It would be easier if you gave an example of what the $services look like.
I will Assume that it will be a group of elements called foo
<foo>value1</foo>
<foo>value2</foo>
<foo>value1</foo>
<foo>value3</foo>
<foo>value2</foo>
Then you can find them the usual way (relying on implicit conversion to
string):
<xsl:for-each select="$services[.!=preceding-sibling::foo]">
Do something
</xsl:for-each>
