Bas ReteraSubject: Question XPath expression (distinct function)

Within my XSL I have to loop through all child elements of a node. That's no problem with xsl:for-each select="*". But I have to exclude some nodes. Some child nodes appear more than 1 times and I only want the first one. In my example you see two bankaccounts and two telephone numbers. I only want to get back the first one of them and all of the rest. A kind of distinct function.

Input XML:
<person>
<name>Jefferson</name>
<forename>Steve</forename>
<bankaccount>987654321</bankaccount>
<bankaccount>123456789</bankaccount>
<telephone>0987654321</telephone>
<telephone>1234567890</telephone>
etc.
</person>

I've found the solution myself.

<xsl:for-each select="*[name()!=name(preceding-sibling::*[position()=1])]">
