I have an element with the value /123/23/22/23/123. I am able to break the string into separate components 123 23 22 23 and 123, but is there a way to remove the duplicates from this element and display them as the output shown below? I am adding both the xml and xslt that I used for it. Please give me some direction on this.

Required Output:

<resource>
<name>123</name>
</resource>
<resource>
<name>23</name>
</resource>
<resource>
<name>22</name>
</resource>

but output that I am getting is:

<resource>
<name>123</name>
</resource>
<resource>
<name>23</name>
</resource>
<resource>
<name>22</name>
</resource>
<resource>
<name>23</name>
</resource>
<resource>
<name>123</name>
</resource>

Here are the programs. Any help on this will be greatly appreciated. Thank you

Very easy in 2.0: call tokenize() to split the string into parts, and then distinct-values() to remove the duplicates.

In 1.0, all problems involving elimination of duplicates essentially boil down into grouping problems - see Muenchian grouping and other techniques at http://www.jenitennison.com/xslt/grouping
