Thank you Martin. I used <xsl:iterate> because I was going to just return the
first match. But I see that I could have just used a [1] predicate.

I am not sure if I can ask this without giving more context, but I have a
function that loops through some regular expressions in a lookup file and
finds matches against a description element. When there is a match, I want to
return an element from my lookup file. I want to return a sequence because
there may be more than one regular expression match. In my function below, it
seems like it is returning a flattened sequence instead of a sequence of
distinct elements. If this isnbt enough context, I can try to mock up a more
complete example. Thank you.

<xsl:function name="rq:get-key-codes">

        <xsl:param name="description" as="xs:string"/>

        <xsl:param name="report-type" as="xs:string"/>

        <xsl:iterate
select="$key-codes/key-codes/record[report[.=$report-type]]">

            <xsl:param name="keyword-codes" as="empty-sequence()"/>

            <xsl:on-completion>{$keyword-codes}</xsl:on-completion>



Here you don't want a text value template but

  <xsl:on-completion select="$keyword-codes"/>



Of course I wonder whether you need the `xsl:iterate` and can't just use

   <xsl:sequence
select="$key-codes/key-codes/record[report[.=$report-type]][matches($descript
ion, key-word,'i')]/key-code"/>
